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.

Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance.

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.

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.

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.

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.

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).

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.

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.

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.

. 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.

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.

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.

Fix class constant fetching If a class is extended after the constant fetch has been cached the cached value will be turned into a reference. On the next fetch the polymorphic cache will return this reference, which will be directly returned. The object assignment code then dereferences this result and performs a shallow copy, which is invalid for references. This subsequently leads to the constant value being prematurely freed. This is fixed by dereferencing the value returned from the polymorphic cache. Furthermore the incorrect dereference from in the object assignment code is replaced with an assertion that we're dealing with a non-reference, so ensure that this kind of problem cannot go unnoticed in the future.

. 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.

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.

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.

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.

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.

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.

SAVE_OPLINE();
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.

Add support for yielding keys Keys are yielded using the yield $key => $value syntax. Currently this is implemented as a statement only and not as an expression, because conflicts arise considering nesting and use in arrays: yield yield $a => $b; // could be either yield (yield $a) => $b; // or yield (yield $a => $b); Once I find some way to resolve these conflicts this should be available as an expression too. 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).

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.

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.
