Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Speed up fetching of class entries for self:: parent:: and static:: This is generalized solution for Bob's idea of speed up self::method() calls without ZEND_FETCH_CLASS. At first, it adds few new opcodes to separate class related behaviour: FETCH_STATIC_PROP_R FETCH_STATIC_PROP_W FETCH_STATIC_PROP_RW FETCH_STATIC_PROP_FUNC_ARG FETCH_STATIC_PROP_UNSET FETCH_STATIC_PROP_IS UNSET_STATIC_PROP ISSET_ISEMPTY_STATIC_PROP FETCH_CLASS_CONSTANT At seconds, it enables IS_UNUSED operand to fetch (self, parent or static without separate FETCH_CLASS) for new opcodes and the following ones: INIT_STATIC_METHOD_CALL NEW END_INSTANCEOF Finaly, opcache optimizer had to be fixed to support new opcodes.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode.

Merge zend_execute_data->called_scope into zend_execute_data->This. "called_scope" made sense only for static method calls, for dynamic calls it was always equal to the class of $this. Now EG(This) may store IS_OBJECT + $this or IS_UNUSED + "called_scope" (of course, "called_scope" may be NULL). Some code might need to be adopted to support this change. Checks (Z_OBJ(EX(This))) might need to be converted into (Z_TYPE(EX(This)) == IS_OBJECT).

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Reduced size of zend_op on 64-bit systems. the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%. The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets. In run-time constant now should be accessed as: RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv EX_CONSTANT(opline->op1) instead of opline->op1.zv Jump targets: OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode.

Reduced size of zend_op on 64-bit systems. the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%. The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets. In run-time constant now should be accessed as: RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv EX_CONSTANT(opline->op1) instead of opline->op1.zv Jump targets: OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

It just locks it incrementing reference counter. If the original array is modified by some code, the copy on write is performed and "foreach" still work with the old copy. - it makes no difference if array given to "foreach by value" is reference itself - "foreach by reference" still use internal array/object pointer and should work similar to PHP-5. (This id not completely implemented)

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Reduced size of zend_op on 64-bit systems. the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%. The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets. In run-time constant now should be accessed as: RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv EX_CONSTANT(opline->op1) instead of opline->op1.zv Jump targets: OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

Refactored parameter passing mechanism. In PHP-5.6 and below each argument passed to user function was copies on VM stack twice. Now we always have ZEND_INIT_FCALL (or simular) opcode that pushes "call frame" on top of VM stack. "Call frame" is actually the same zend_execute_data structure. All the following ZEND_SEND instructions push arguments on top of the stack in a way that they directly comes into corresponding CV variables of the called frame. Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance. There are two minor incompatibilities: 1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}". 2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Merge zend_execute_data->called_scope into zend_execute_data->This. "called_scope" made sense only for static method calls, for dynamic calls it was always equal to the class of $this. Now EG(This) may store IS_OBJECT + $this or IS_UNUSED + "called_scope" (of course, "called_scope" may be NULL). Some code might need to be adopted to support this change. Checks (Z_OBJ(EX(This))) might need to be converted into (Z_TYPE(EX(This)) == IS_OBJECT).

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

USE_OPLINE
Refactored parameter passing mechanism. In PHP-5.6 and below each argument passed to user function was copies on VM stack twice. Now we always have ZEND_INIT_FCALL (or simular) opcode that pushes "call frame" on top of VM stack. "Call frame" is actually the same zend_execute_data structure. All the following ZEND_SEND instructions push arguments on top of the stack in a way that they directly comes into corresponding CV variables of the called frame. Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance. There are two minor incompatibilities: 1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}". 2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Moved zend_literal->cache_slot right into zval. It should be accessed using Z_CACHE_SLOT() macro. zend_literal structure is removed. API functions that accepted pointer to zend_literal now accept pointer to zval or cache_slot directly. Calls of such functiond that now accept cache_slot need to be changed to pass -1 instead of NULL.

Refactored parameter passing mechanism. In PHP-5.6 and below each argument passed to user function was copies on VM stack twice. Now we always have ZEND_INIT_FCALL (or simular) opcode that pushes "call frame" on top of VM stack. "Call frame" is actually the same zend_execute_data structure. All the following ZEND_SEND instructions push arguments on top of the stack in a way that they directly comes into corresponding CV variables of the called frame. Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance. There are two minor incompatibilities: 1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}". 2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Reduced size of zend_op on 64-bit systems. the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%. The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets. In run-time constant now should be accessed as: RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv EX_CONSTANT(opline->op1) instead of opline->op1.zv Jump targets: OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

Refactored parameter passing mechanism. In PHP-5.6 and below each argument passed to user function was copies on VM stack twice. Now we always have ZEND_INIT_FCALL (or simular) opcode that pushes "call frame" on top of VM stack. "Call frame" is actually the same zend_execute_data structure. All the following ZEND_SEND instructions push arguments on top of the stack in a way that they directly comes into corresponding CV variables of the called frame. Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance. There are two minor incompatibilities: 1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}". 2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

2012-05-13 13:12:48 +08:00
Reduced size of zend_op on 64-bit systems. the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%. The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets. In run-time constant now should be accessed as: RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv EX_CONSTANT(opline->op1) instead of opline->op1.zv Jump targets: OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance. There are two minor incompatibilities: 1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}". 2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance. There are two minor incompatibilities: 1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}". 2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

FREE_OP1();
Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Refactored parameter passing mechanism. In PHP-5.6 and below each argument passed to user function was copies on VM stack twice. Now we always have ZEND_INIT_FCALL (or simular) opcode that pushes "call frame" on top of VM stack. "Call frame" is actually the same zend_execute_data structure. All the following ZEND_SEND instructions push arguments on top of the stack in a way that they directly comes into corresponding CV variables of the called frame. Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance. There are two minor incompatibilities: 1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}". 2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Reduced size of zend_op on 64-bit systems. the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%. The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets. In run-time constant now should be accessed as: RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv EX_CONSTANT(opline->op1) instead of opline->op1.zv Jump targets: OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

Speed up fetching of class entries for self:: parent:: and static:: This is generalized solution for Bob's idea of speed up self::method() calls without ZEND_FETCH_CLASS.

Refactored parameter passing mechanism. In PHP-5.6 and below each argument passed to user function was copies on VM stack twice. Now we always have ZEND_INIT_FCALL (or simular) opcode that pushes "call frame" on top of VM stack. "Call frame" is actually the same zend_execute_data structure. All the following ZEND_SEND instructions push arguments on top of the stack in a way that they directly comes into corresponding CV variables of the called frame. Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance. There are two minor incompatibilities: 1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}". 2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

. The VM stacks for passing function arguments and syntaticaly nested calls were merged into a single stack. The stack size needed for op_array execution is calculated at compile time and preallocated at once. As result all the stack push operatins don't require checks for stack overflow any more. . Generators implementation was improved using the new VM stack. Now it's a bit more clear and faster.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode.

ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed iter leak on by-ref foreach over const/tmp array FE_FREE does not unregister the iter for plain arrays. So always wrap into a REF wrapper, even if not strictly necessary, in RESET_RW. Alternatively we could use a flag to distinguish plain positions and interators. Also added a check for leaked iterators in shutdown_executor.

FREE_OP1_VAR_PTR();
Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

It just locks it incrementing reference counter. If the original array is modified by some code, the copy on write is performed and "foreach" still work with the old copy. - it makes no difference if array given to "foreach by value" is reference itself - "foreach by reference" still use internal array/object pointer and should work similar to PHP-5.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Changed HashTable layout: Removed HashTable->arHash (reduced memory consumption). Now hash slots may be accessed using HT_HASH() macro. Hash slotas are allocated together with Buckets (before them) and lay in reverse order from HashTable->arData base address (see comments in Zend/zend_types.h) Indexes in hash table and conflict resolution chains (Z_NEXT) may be stored as indeces or offsets in bytes, depending on system (32 or 64-bit). HashTable data filelds are reordered to keep the most useful for zend_hash_find() data in the same CPU cache line.

Changed HashTable layout: Removed HashTable->arHash (reduced memory consumption). Now hash slots may be accessed using HT_HASH() macro. Hash slotas are allocated together with Buckets (before them) and lay in reverse order from HashTable->arData base address (see comments in Zend/zend_types.h) Indexes in hash table and conflict resolution chains (Z_NEXT) may be stored as indeces or offsets in bytes, depending on system (32 or 64-bit). HashTable data filelds are reordered to keep the most useful for zend_hash_find() data in the same CPU cache line.

Changed HashTable layout: Removed HashTable->arHash (reduced memory consumption). Now hash slots may be accessed using HT_HASH() macro. Hash slotas are allocated together with Buckets (before them) and lay in reverse order from HashTable->arData base address (see comments in Zend/zend_types.h) Indexes in hash table and conflict resolution chains (Z_NEXT) may be stored as indeces or offsets in bytes, depending on system (32 or 64-bit). HashTable data filelds are reordered to keep the most useful for zend_hash_find() data in the same CPU cache line.

Speed up fetching of class entries for self:: parent:: and static:: This is generalized solution for Bob's idea of speed up self::method() calls without ZEND_FETCH_CLASS. At first, it adds few new opcodes to separate class related behaviour: FETCH_STATIC_PROP_R FETCH_STATIC_PROP_W FETCH_STATIC_PROP_RW FETCH_STATIC_PROP_FUNC_ARG FETCH_STATIC_PROP_UNSET FETCH_STATIC_PROP_IS UNSET_STATIC_PROP ISSET_ISEMPTY_STATIC_PROP FETCH_CLASS_CONSTANT At seconds, it enables IS_UNUSED operand to fetch (self, parent or static without separate FETCH_CLASS) for new opcodes and the following ones: INIT_STATIC_METHOD_CALL NEW END_INSTANCEOF Finaly, opcache optimizer had to be fixed to support new opcodes.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE().

Improved ternary operator performance when returning arrays

}
Reduced size of zend_op on 64-bit systems. the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%. The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets. In run-time constant now should be accessed as: RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv EX_CONSTANT(opline->op1) instead of opline->op1.zv Jump targets: OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE().

Remove uses of VARs in extended_value The DECLARE_(ANON_)INHERITED_CLASS(_DELAYED) opcodes were referencing the parent ce VAR through extended_value. This is hacky and we can't track the def-use chain in SSA. To avoid this, the layout of declaration opcodes is changed as follows: op1 points to the lcname and rtd_key literals, in that order. (For anon/lambda declarations only one of lcname or rtd_key is present.) This frees up op2, which is now used to reference the parent ce VAR in inheriting declarations.

Reduced size of zend_op on 64-bit systems. the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%. The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets. In run-time constant now should be accessed as: RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv EX_CONSTANT(opline->op1) instead of opline->op1.zv Jump targets: OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

Speed up fetching of class entries for self:: parent:: and static:: This is generalized solution for Bob's idea of speed up self::method() calls without ZEND_FETCH_CLASS. At first, it adds few new opcodes to separate class related behaviour: FETCH_STATIC_PROP_R FETCH_STATIC_PROP_W FETCH_STATIC_PROP_RW FETCH_STATIC_PROP_FUNC_ARG FETCH_STATIC_PROP_UNSET FETCH_STATIC_PROP_IS UNSET_STATIC_PROP ISSET_ISEMPTY_STATIC_PROP FETCH_CLASS_CONSTANT At seconds, it enables IS_UNUSED operand to fetch (self, parent or static without separate FETCH_CLASS) for new opcodes and the following ones: INIT_STATIC_METHOD_CALL NEW END_INSTANCEOF Finaly, opcache optimizer had to be fixed to support new opcodes.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE(). As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

Also the key yielding code is rather copy-and-past-y for the value yielding code, so that should be factored out.

Remove asterix modifier (*) for generators Generators are now automatically detected by the presence of a `yield` expression in their body. This removes the ZEND_SUSPEND_AND_RETURN_GENERATOR opcode. Instead additional checks for ZEND_ACC_GENERATOR are added to the fcall_common helper and zend_call_function. This also adds a new function zend_generator_create_zval, which handles the actual creation of the generator zval from an op array. I feel like I should deglobalize the zend_create_execute_data_from_op_array code a bit. It currently changes EG(current_execute_data) and EG(opline_ptr) which is somewhat confusing (given the name).

Reduced size of zend_op on 64-bit systems. the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%. The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets. In run-time constant now should be accessed as: RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv EX_CONSTANT(opline->op1) instead of opline->op1.zv Jump targets: OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

Reduced size of zend_op on 64-bit systems. the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%. The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets. In run-time constant now should be accessed as: RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv EX_CONSTANT(opline->op1) instead of opline->op1.zv Jump targets: OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

Remove EXT_TYPE_UNUSED in favor of IS_UNUSED This means we no longer allocate an unused VAR for the retval of instructions that support unused results. Nearly all instructions already used the result variable only if it was used. The only exception to this was the return value variable for internal function call results. I've adjusted the code to use a stack zval for the unused return case now. As we have retval specialization now, we know that it doesn't matter.

Properly define ZEND_OP_DATA in zend_vm_def.h This allows zend_vm_gen.php to define them in zend_vm_opcodes.{c,h} without further hacks.
2015-04-20 05:21:57 +08:00
Introduce BIND_LEXICAL This opcodes inserts a local CV into the closure static variable table. This replaces the previous mechanism of having static variables marked as LEXICAL, which perform a symtable lookup during copying. This means a) functions which contain closures no longer have to rebuild their symtable (better performance) and b) we can now track used variables in SSA.
