c4413e2c9b * c-exp.y (exp:STRING): Convert C strings into array-of-char
constants with an explicit null byte terminator.  OP_STRING is
	now used for real string types.

	are printed as strings to be consistent with the way strings
	are printed when pointer-to-char types are dereferenced.

85f0a8484f * gdbtypes.c (create_array_type): Complete rewrite. Now requires

	cannot be an implementation defined type, complain as well.

dac4929a6d * mips-tdep.c, mipsread.c, tm-mips.h: Get rid of ".gdbinfo."
symbol.  #define MIPS_EFI_SYMBOL_NAME instead.  Use different
value so that demangler won't be invoked.  This greatly speeds up
stepping.
* mips-tdep.c (mips_pop_frame):  Rewrite handling of
linked_proc_info so that it properly deallocates the appropriate
item after it is done with it instead of before.
* Don't pass bogus frame pointer to create_new_frame().  Just
leave it as zero so that lower level code will figure out the
correct value.

fa0bcaa3a5 * mipsread.c: Undo ill effects from including <strings.h>,
which #defines index to be strchr.  Unfortunately, index is
	a member of a symbol table structure that can't be changed.
	* mipsread.c:  tm-mips.h includes coff/symconst.h and coff/sym.h,
	remove redundant #include's.

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).

	for clarity.  Set top_stack before calling parse_external.  In

	FILE *'s when debugging GDB (e.g. as args to dump_symtab).

	makes.  Eliminate doc/Makefile from tar.Z file if doc/Makefile.in
	exists.

4ad1963ee0 * mipsread.c (fixup_sigtramp): Also look for _sigtramp as a real
routine (for Irix-4.x).  Make many funcs static and void.
* mips-tdep.c (mips-frame-chain):  Clean up, simplify.
* (init_extra_frame_info):  Don't trash cached value of frame
pointer register.  This fixes backtracing through routines that use
alloca().  Generally clean up declarations of functions, and use
typedefs and macros to reference data structures as appropriate.
* tm-irix3.h, tm-mips.h (EXTRA_FRAME_INFO):  use proper type for
proc_desc element.
1992-04-03 03:55:42 +00:00
Stu Grossman
d1bb1d4170 * mipsread.c (parse_symbol, parse_procedure): Re-do the way that
.gdbinfo. symbols are created.  Move creation from parse_procedure
to parse_symbol, where it is fairly easy to grow the symtab.  This
also fixes a symtab trashing bug on all mips-based systems.
* (got_numargs, lookup_numargs, free_numargs):  Delete.  Not
needed anymore.
* tm-mips.h, tm-iris3.h, mips-tdep.c, mipsread.c:  Re-do struct
mips_extra_func_info, and all the PROC_xxx macros that look at it.

* objfiles.c (have_partial_symbols, have_full_symbols,
have_minimal_symbols):  explicit iteration => ALL_OBJFILES; simplify.
(iterate_over_objfiles, iterate_over_symtabs,
iterate_over_psymtabs):  Remove, clunky and slow.
* objfiles.h:  Replace iterate_over_* prototypes with ALL_SYMTABS,
ALL_PSYMTABS, and ALL_MSYMBOLS macros.
* symmisc.c (dump_symtab, dump_psymtab, dump_msymbols,
dump_objfile):  Remove dummy args and results.  Move filename
comparisons to callers.

printobjfiles_command):  iterate_over_* => ALL_*.  Compare filenames.
* symtab.c (lookup_symtab_1, lookup_symtab, lookup_partial_symtab,
lookup_symbol, find_main_psymtab, find_pc_symtab, sources_info,
list_symbols, make_symbol_completion_list):  Replace explicit
iteration with ALL_SYMTABS, ALL_PSYMTABS, or ALL_MSYMBOLS.
Eliminate Dijkstra flag crap, break out of loops with gotos.
(lookup_symtab_1):  Protect '/' tests from short filenames.
(cplus_mangled_symbol):  Move inline into lookup_symbol.
* xcoffexec.c (relocate_objfile_msymbols):  Remove poor hack.
(relocate_minimal_symbol):  Move inline to vmap_symtab.
(vmap_symtab):  Replace iteration with ALL_OBJFILES,
iterate_over_msymbols with ALL_MSYMBOLS.

Misc cleanup prior to release.

* mipsread.c (compare_symtabs, compare_psymtabs):  Remove, unused.
* mipsread.c:  Add prototypes for all static functions.

* symmisc.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl):  Remove, unused.
* xcoffread.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl):  Remove 2nd
unused copy!

* buildsym.c (define_symbol):  Handle global register variables
(from Pierre Willard).  Complain if register numbers are too large.

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.

Fred Fish
80d68b1d49 * coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,
elfread.c (coff_symfile_finish):  Add function, prototype, and
	add to the xxxx_sym_fns struct for each file type.  Also reformat

	elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
	Pass pointer to struct objfile rather than pointer to sym_fns.
	Change references inside each function accordingly.  Allocate any
	symbol file specific info in the per-objfile memory region.
	* dbxread.c (free_and_init_header_files):  Break function into
	free_header_files(), called from dbx_symfile_finish(), and

	* dbxread.c (dbx_new_init):  Move deallocation things to new
	dbx_symfile_finish function.
	* elfread.c (elf_new_init):  Call buildsym_new_init().

	routine for the objfile before deallocating other stuff.
	* sparc-tdep.c (get_longjmp_target):  Cast target_read_memory arg.
	* symfile.h:  Move struct sym_fns to before struct objfile def.
	Add sym_finish function pointer and change prototypes of other
	function pointers to reflect passing struct objfile pointer rather
	than struct sym_fns pointer.
	* symfile.c:  Remove now obsolete symtab_fns pointer.
	* symfile.c (symfile_init):  Renamed to find_sym_fns, and now only
	locates the correct sym_fns struct for the given objfile.

	for better support of mapped symbol tables.
	* symfile.c (symbol_file_command):  Remove obsolete code using

* 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.)

021959e249 * xm-sun3os4.h, xm-sun4os4.h: Enable HAVE_MMAP.
* minsyms.c (install_minimal_symbols):  Add bunches to any
existing minsyms in the objfile.  Avoid extra mallocation
by working directly in the obstack.  Remove ignored `mainline' parm.
* coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
xcoffread.c:  Change all callers.
* FIXME:  We should be able to eliminate MAINLINE from all the
symbol readers now, with a small bit of work.

* valops.c, value.h:  Lint.
* remote-vx.c:  Add missing break; statement.  Bugfix by
Michael Sclafani, <sclafani@src.dec.com>.

778c358df8 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when

only assuming union if multiple members have offsets of zero.

John Gilmore
c55e616795 Handle debug symbols in dynamically loaded (relocated) code:
* dbxread.c (read_ofile_symtab):  Fix up N_CATCH better.  Pass
offset to process_one_symbol.
(process_one_symbol):  Take new offset parameter.  Add it into
appropriate symbol types to relocate symbols to loaded addresses.
Handle all possible symbol types, and complain() about types that
we don't expect to see.
* mipsread.c (psymtab_to_symtab_1):  Pass offset of zero to
process_one_symbol (FIXME, should pass real offset).

Misc bugfixes:

* breakpoint.c (resolve_sal_pc):  Split out code to resolve a
sal's PC value.
(set_breakpoint, break_command_1, until_break_command,
catch_command_1, breakpoint_re_set_one):  Use it.
(breakpoint_re_set_one):  Disable bkpts that don't re-set cleanly.
(breakpoint_re_set):  Mention breakpoint number in error messages.
* symtab.h (resolve_sal_pc):  Declare.

* source.c (find_source_lines):  Avoid "Source file is more
recent than executable" when bfd_get_mtime gives 0.
(list_command):  Shorten "FILE, line N" to "FILE:N".

* putenv.c (putenv):  Avoid unportably casting pointers to unsigneds.
