* README: Remove note about gcc warnings on alpha, these should be
gone now.
* c-exp.y, ch-exp.y, core.c, corelow.c, eval.c, fork-child.c,
m2-exp.y, minsyms.c, nlmread.c, parse.c, putenv.c, regex.c
remote-utils.c, stabsread.c: Include <string.h>.
* regex.c: Include "defs.h", change re_comp argument to const char *.
* infptrace.c (fetch_register, store_inferior_registers): Change
regaddr to type CORE_ADDR.
* config/alpha/alpha-nw.mt, config/alpha/alpha-osf1.mt (MT_CFLAGS):
Remove, no longer necessary now that we use bfd_vma for a CORE_ADDR.

/* Parse a C expression from text in a string,
|
|
|
|
|
and return the result as a struct expression pointer.
|
|
|
|
|
That structure contains arithmetic operations in reverse polish,
|
|
|
|
|
with constants represented by operations that are followed by special data.
|
|
|
|
|
See expression.h for the details of the format.
|
|
|
|
|
What is important here is that it can be built up sequentially
|
|
|
|
|
during the process of parsing; the lower levels of the tree always
|
1992-10-31 08:35:08 +08:00
|
|
|
|
come first in the result.
|
|
|
|
|
|
|
|
|
|
Note that malloc's and realloc's in this file are transformed to
|
|
|
|
|
xmalloc and xrealloc respectively by the same sed command in the
|
|
|
|
|
makefile that remaps any other malloc/realloc inserted by the parser
|
|
|
|
|
generator. Doing this with #defines and trying to control the interaction
|
|
|
|
|
with include files (<malloc.h> and <stdlib.h> for example) just became
|
|
|
|
|
too messy, particularly when such includes can be inserted at random
|
|
|
|
|
times by the parser generator. */

* Add native support for long double data type.
* c-exp.y (%union): Change dval to typed_val_float. Use DOUBLEST
to store actual data. Change types of INT and FLOAT tokens to
typed_val_int and typed_val_float respectively. Create new token
DOUBLE_KEYWORD to specify the string `double'. Make production
for FLOAT use type determined by parse_number. Add production for
"long double" data type.
* (parse_number): Use sscanf to parse numbers as float, double or
long double depending upon the type of typed_val_float.dval. Also
allow user to specify `f' or `l' suffix to explicitly specify
float or long double constants. Change typed_val to
typed_val_int.
* (yylex): Change typed_val to typed_val_int. Also, scan for
"double" keyword.
* coffread.c (decode_base_type): Add support for T_LNGDBL basic
type.
* configure, configure.in: Add check for long double support in
the host compiler.
* defs.h: Define DOUBLEST appropriatly depending on whether
HAVE_LONG_DOUBLE (from autoconf) is defined. Also, fix prototypes
for functions that handle this type.
* expression.h (union exp_element): doubleconst is now type
DOUBLEST.
* m2-exp.y f-exp.y (%union): dval becomes type DOUBLEST.
* findvar.c (extract_floating): Make return value be DOUBLEST.
Also, add support for numbers with size of long double.
* (store_floating): Arg `val' is now type DOUBLEST. Handle all
floating types.
* parser-defs.h parse.c (write_exp_elt_dblcst): Arg expelt is now
DOUBLEST.

* Add native support for long double data type.
* c-exp.y (%union): Change dval to typed_val_float. Use DOUBLEST
to store actual data. Change types of INT and FLOAT tokens to
typed_val_int and typed_val_float respectively. Create new token
DOUBLE_KEYWORD to specify the string `double'. Make production
for FLOAT use type determined by parse_number. Add production for
"long double" data type.
* (parse_number): Use sscanf to parse numbers as float, double or
long double depending upon the type of typed_val_float.dval. Also
allow user to specify `f' or `l' suffix to explicitly specify
float or long double constants. Change typed_val to
typed_val_int.
* (yylex): Change typed_val to typed_val_int. Also, scan for
"double" keyword.
* coffread.c (decode_base_type): Add support for T_LNGDBL basic
type.
* configure, configure.in: Add check for long double support in
the host compiler.
* defs.h: Define DOUBLEST appropriatly depending on whether
HAVE_LONG_DOUBLE (from autoconf) is defined. Also, fix prototypes
for functions that handle this type.
* expression.h (union exp_element): doubleconst is now type
DOUBLEST.
* m2-exp.y f-exp.y (%union): dval becomes type DOUBLEST.
* findvar.c (extract_floating): Make return value be DOUBLEST.
Also, add support for numbers with size of long double.
* (store_floating): Arg `val' is now type DOUBLEST. Handle all
floating types.
* parser-defs.h parse.c (write_exp_elt_dblcst): Arg expelt is now
DOUBLEST.
* valarith.c (value_binop): Change temp variables v1, v2 and v to
type DOUBLEST. Coerce type of result to long double if either op
was of that type.
* valops.c (value_arg_coerce): If argument type is bigger than
double, coerce to long double.
* (call_function_by_hand): If REG_STRUCT_HAS_ADDR is defined, and
arg type is float and > 8 bytes, then use pointer-to-object
calling conventions.
* valprint.c (print_floating): Arg doub is now type DOUBLEST.
Use appropriate format and precision to print out floating point
values.
* value.h: Fixup prototypes for value_as_double,
value_from_double, and unpack_double to use DOUBLEST.
* values.c (record_latest_value): Remove check for invalid
floats. Allow history to store them so that people may examine
them in hex if they want.
* (value_as_double unpack_double): Change return value to DOUBLEST.
* (value_from_double): Arg `num' is now DOUBLEST.
* (using_struct_return): Use RETURN_VALUE_ON_STACK macro (target
specific) to expect certain types to always be returned on the stack.

* Add native support for long double data type.
* c-exp.y (%union): Change dval to typed_val_float. Use DOUBLEST
to store actual data. Change types of INT and FLOAT tokens to
typed_val_int and typed_val_float respectively. Create new token
DOUBLE_KEYWORD to specify the string `double'. Make production
for FLOAT use type determined by parse_number. Add production for
"long double" data type.
* (parse_number): Use sscanf to parse numbers as float, double or
long double depending upon the type of typed_val_float.dval. Also
allow user to specify `f' or `l' suffix to explicitly specify
float or long double constants. Change typed_val to
typed_val_int.
* (yylex): Change typed_val to typed_val_int. Also, scan for
"double" keyword.
* coffread.c (decode_base_type): Add support for T_LNGDBL basic
type.
* configure, configure.in: Add check for long double support in
the host compiler.
* defs.h: Define DOUBLEST appropriatly depending on whether
HAVE_LONG_DOUBLE (from autoconf) is defined. Also, fix prototypes
for functions that handle this type.
* expression.h (union exp_element): doubleconst is now type
DOUBLEST.
* m2-exp.y f-exp.y (%union): dval becomes type DOUBLEST.
* findvar.c (extract_floating): Make return value be DOUBLEST.
Also, add support for numbers with size of long double.
* (store_floating): Arg `val' is now type DOUBLEST. Handle all
floating types.
* parser-defs.h parse.c (write_exp_elt_dblcst): Arg expelt is now
DOUBLEST.
* valarith.c (value_binop): Change temp variables v1, v2 and v to
type DOUBLEST. Coerce type of result to long double if either op
was of that type.
* valops.c (value_arg_coerce): If argument type is bigger than
double, coerce to long double.
* (call_function_by_hand): If REG_STRUCT_HAS_ADDR is defined, and
arg type is float and > 8 bytes, then use pointer-to-object
calling conventions.
* valprint.c (print_floating): Arg doub is now type DOUBLEST.
Use appropriate format and precision to print out floating point
values.
* value.h: Fixup prototypes for value_as_double,
value_from_double, and unpack_double to use DOUBLEST.
* values.c (record_latest_value): Remove check for invalid
floats. Allow history to store them so that people may examine
them in hex if they want.
* (value_as_double unpack_double): Change return value to DOUBLEST.
* (value_from_double): Arg `num' is now DOUBLEST.
* (using_struct_return): Use RETURN_VALUE_ON_STACK macro (target
specific) to expect certain types to always be returned on the stack.

to store actual data. Change types of INT and FLOAT tokens to
typed_val_int and typed_val_float respectively. Create new token
DOUBLE_KEYWORD to specify the string `double'. Make production
for FLOAT use type determined by parse_number. Add production for
"long double" data type.
* (parse_number): Use sscanf to parse numbers as float, double or
long double depending upon the type of typed_val_float.dval. Also
allow user to specify `f' or `l' suffix to explicitly specify
float or long double constants. Change typed_val to
typed_val_int.
* (yylex): Change typed_val to typed_val_int. Also, scan for
"double" keyword.
* coffread.c (decode_base_type): Add support for T_LNGDBL basic
type.
* configure, configure.in: Add check for long double support in
the host compiler.
* defs.h: Define DOUBLEST appropriatly depending on whether
HAVE_LONG_DOUBLE (from autoconf) is defined. Also, fix prototypes
for functions that handle this type.
* expression.h (union exp_element): doubleconst is now type
DOUBLEST.
* m2-exp.y f-exp.y (%union): dval becomes type DOUBLEST.
* findvar.c (extract_floating): Make return value be DOUBLEST.
Also, add support for numbers with size of long double.
* (store_floating): Arg `val' is now type DOUBLEST. Handle all
floating types.
* parser-defs.h parse.c (write_exp_elt_dblcst): Arg expelt is now
DOUBLEST.
* valarith.c (value_binop): Change temp variables v1, v2 and v to
type DOUBLEST. Coerce type of result to long double if either op
was of that type.
* valops.c (value_arg_coerce): If argument type is bigger than
double, coerce to long double.
* (call_function_by_hand): If REG_STRUCT_HAS_ADDR is defined, and
arg type is float and > 8 bytes, then use pointer-to-object
calling conventions.
* valprint.c (print_floating): Arg doub is now type DOUBLEST.
Use appropriate format and precision to print out floating point
values.
* value.h: Fixup prototypes for value_as_double,
value_from_double, and unpack_double to use DOUBLEST.
* values.c (record_latest_value): Remove check for invalid
floats. Allow history to store them so that people may examine
them in hex if they want.
* (value_as_double unpack_double): Change return value to DOUBLEST.
* (value_from_double): Arg `num' is now DOUBLEST.
* (using_struct_return): Use RETURN_VALUE_ON_STACK macro (target
specific) to expect certain types to always be returned on the stack.

to store actual data. Change types of INT and FLOAT tokens to
typed_val_int and typed_val_float respectively. Create new token
DOUBLE_KEYWORD to specify the string `double'. Make production
for FLOAT use type determined by parse_number. Add production for
"long double" data type.
* (parse_number): Use sscanf to parse numbers as float, double or
long double depending upon the type of typed_val_float.dval. Also
allow user to specify `f' or `l' suffix to explicitly specify
float or long double constants. Change typed_val to
typed_val_int.
* (yylex): Change typed_val to typed_val_int. Also, scan for
"double" keyword.
* coffread.c (decode_base_type): Add support for T_LNGDBL basic
type.
* configure, configure.in: Add check for long double support in
the host compiler.
* defs.h: Define DOUBLEST appropriatly depending on whether
HAVE_LONG_DOUBLE (from autoconf) is defined. Also, fix prototypes
for functions that handle this type.
* expression.h (union exp_element): doubleconst is now type
DOUBLEST.
* m2-exp.y f-exp.y (%union): dval becomes type DOUBLEST.
* findvar.c (extract_floating): Make return value be DOUBLEST.
Also, add support for numbers with size of long double.
* (store_floating): Arg `val' is now type DOUBLEST. Handle all
floating types.
* parser-defs.h parse.c (write_exp_elt_dblcst): Arg expelt is now
DOUBLEST.
* valarith.c (value_binop): Change temp variables v1, v2 and v to
type DOUBLEST. Coerce type of result to long double if either op
was of that type.
* valops.c (value_arg_coerce): If argument type is bigger than
double, coerce to long double.
* (call_function_by_hand): If REG_STRUCT_HAS_ADDR is defined, and
arg type is float and > 8 bytes, then use pointer-to-object
calling conventions.
* valprint.c (print_floating): Arg doub is now type DOUBLEST.
Use appropriate format and precision to print out floating point
values.
* value.h: Fixup prototypes for value_as_double,
value_from_double, and unpack_double to use DOUBLEST.
* values.c (record_latest_value): Remove check for invalid
floats. Allow history to store them so that people may examine
them in hex if they want.
* (value_as_double unpack_double): Change return value to DOUBLEST.
* (value_from_double): Arg `num' is now DOUBLEST.
* (using_struct_return): Use RETURN_VALUE_ON_STACK macro (target
specific) to expect certain types to always be returned on the stack.
