Steve Chamberlain 2e6edad13c * c-exp.y: separated host/target idea of integer type size,
removed redundant parse rules. (YYSTYPE): added typed_val, removed
	UINT and CHAR rules. (parse_number): work out the targetwise type
	of a number based upon it's size and qualifiers. (yylex): chars
	are now treated the same way as ints.

	* source.c (indentify_source_line): don't core dump if wanted
	line is larger than number of lines in source. (can happen when
	coff gets confused about #included source).

Fred Fish e35843d476 * Makefile.in (c-exp.tab.c, m2-exp.tab.c): Add sed patterns to
remap all malloc's to xmalloc's and all realloc's to xrealloc's.
	* c-exp.y, m2-exp.y:  Add comment about how malloc/realloc are
	  remapped to xmalloc/xrealloc, use only malloc/realloc in grammer
	  file.  Remove preprocessor defines that previously did remapping.

Per Bothner 10a297b791 * c-exp.y: Moved handling of 'const' and 'volatile' from
<type> to <typebase>.  This removes 2 conflicts.

John Gilmore 2640f7e138 Removed a large number of changes inserted by Per Bothner
for C++ support.  These will go back in when they've been
examined.

Per Bothner 35fcebce93 A ton of changes to improve C++ debugging. See ChangeLog. 1992-09-04 07:37:18 +00:00
Per Bothner a252e71520 * gdbtypes.c, gdbtypes.h: New function lookup_signed_typename.
* c-exp.y:  Call lookup_signed_typename() after seeing
	"signed".  This handles "signed char" correctly.
	* c-exp.y:  Recognize (but ignore) 'const' and 'volatile'
	keywords before a type specifier.

Fred Fish 1867b3be84 Back out of TYPE_FLAG_FUND_TYPE change, solve the problem in valprint.c by
just printing the type name from the type if it is not otherwise handled.
Implement new handling of the ".syms" file for reusable symbol files.
1992-04-18 02:30:28 +00:00
Fred Fish 4a11eef2eb Add TYPE_FLAG_FUND_TYPE bit to the flags member of the type structure,
and use it to decide when to print the actual type name rather than
trying to invent the name of a fundamental type.  This clears up the
confusion between int/long when they are the same sizes, removes one
obstacle to multi-language support (previously valprint.c thought
everything was a C type), and allows gdb to support distinctions between
explicitly and implicitly signed types when the compiler supports such
distinction in the debug output (as does every ANSI compiler I tested
except for gcc).
