Fred Fish
8f793aa541 * Makefile.in (DEMANGLER): Define and default to cplus-dem.
Allows selection of C++ demangler to be a configuration option
	until multiple demanglers are supported.
	* demangle.h:  New include file for extended demangler support.
	* breakpoint.c, gdbtypes.c, printcmd.c, stack.c, symtab.c,

	to print demangled function args.  Still broken, but now less so.

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).
1992-04-15 05:42:00 +00:00

ac88ca205c Lint.
* symfile.c (add_symbol_file_command):  Initialize mapped/readnow.

c2e4669f8c Misc cleanups from code review. 1992-03-27 23:56:15 +00:00
Fred Fish
5e2e79f859 Many changes, most related to creating entry point information on a per-objfile
basis.  See comments in objfiles.h and details in ChangeLog.  Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.
1992-03-21 01:56:01 +00:00
Fred Fish
318bf84ffe Globs of changes. See the ChangeLog for details. Most related to
using the new mmalloc package.

* All GDB files that #include defs.h: Removed stdio.h.
	(defs.h): #include stdio.h.

This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion.  (n.b.
many configurations don't build for other reasons.)

Steve Chamberlain
96743d3c30 * gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of
a ptype to reflect the setting of TARGET_PTR_BIT.  Set the
	TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED.
	* tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint
	* printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use
	it before printing out the hex shape of an address.
1992-03-03 07:05:23 +00:00

93fe4e330e Saberlint.
