Fred Fish
95ff889ecd * dwarfread.c (cu_language): New local variable to record
language for current compilation unit being processed.
	* dwarfread.c (set_cu_language):  New local function to decode
	and record language for current compilation unit being processed.
	* dwarfread.c (synthesize_typedef):  Add local function to
	synthesize a typedef for C++ classes, structs, unions, and
	enumerations.
	* dwarfread.c (read_structure_scope):  Synthesize typedefs
	for C++ classes, structs and unions.
	* dwarfread.c (read_enumeration):  Synthesize typedefs for
	C++ enumerations.
	* dwarfread.c (read_file_scope):   Call set_cu_language to
	record language for current compilation unit.  After symtab
	is built, save this recorded language.
	* dwarfread.c (process_dies, add_partial_symbol, struct_type,
	scan_partial_symbols, new_symbol):  Recognize TAG_class_type.
	* dwarfread.c (add_partial_symbol):  Synthesize partial symbol
	typedefs for C++ classes, structs, unions, and enumerations.

	to record language for current compilation unit.
	* dwarfread.c (scan_partial_symbols):  Call add_enum_psymbol here
	for TAG_enumeration_types, rather than in add_partial_symbol.
	* dwarfread.c (add_partial_symbol):  Combine TAG_enumeration_type
	case with class, struct, and union type cases, now that they are
	the same.  Remove tests for non-NULL name attributes, now done
	by callers.
	* gdbtypes.h (TYPE_CODE_CLASS):  Add type for C++ classes, but
	treat as alias for TYPE_CODE_STRUCT for now.

ea1549b346 * gdbtypes.c (make_{reference,pointer,function}_type): New
functions which handle overwriting of forward-referenced types
for stabs file reading.
(lookup_{reference,pointer,function}_type):  These just call
the make_*_type functions with a null storage alloc parameter.
* gdbtypes.h (make_{reference,pointer,function}_type):  Declare.
* xcoffread.c (smash_to_pointer_type):  Remove, no longer used.

* buildsym.c (dbx_lookup_type):  Zero result for (-1,-1) arg.
(dbx_alloc_type):  Make it easier to understand.  No funct change.
(define_symbol: 't'):  Don't put the typedef name into the name of
the struct, union, or enum.  Bugfix.
(read_type: '*', '&', 'f'):  Add comments.  Use make_XXX_type
routines to properly handle overwriting preallocated types so that
forward references will work.
(read_enum_type):  Force enum values to file scope, due to bug in
Sun compiler output.  FIXME, fix later.

Remove unused header_file_prev_index mechanism.  It was already
obsolete in gdb-3.5.  These comments appeared in 3.5:
  /* This code was used before I knew about the instance codes.
     My first hypothesis is that it is not necessary now
     that instance codes are handled.  */
* dbxread.c (add_new_header_file):  Remove header_file_prev_index.
* buildsym.h:  Remove it and prev_index that saves it.
* buildsym.c (push_subfile, pop_subfile, start_symtab):  Remove it.

* solib.c (special_symbol_handling):  When called from core files,
must set up debug_addr.  Don't print error messages, just return.
* symmisc.c (print_symbol):  Less ascii diarrhea for enums, please.

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).
