* mdebugread.c (CUR_SYMBOL_TYPE, CUR_SYMBOL_VALUE, START_PSYMTAB,
        END_PSYMTAB, SET_NAMESTRING, HANDLE_RBRAC): Delete definitions.
        (parse_partial_symbols): Don't include partial-stab.h any
        more. Don't reuse code in partial-stab.h, include the code
        directly, instead. Simplify code from partial-stab.h eliminating
        ifdef DBXREAD_ONLY code.

        * Makefile.in (mdebugread.o): Remove dependency on partial-stab.h.

Jim Blandy 3973eaddf4 Isolate STABS readers' use of the `textlow' and `texthigh' fields
of `struct partial_symtab' to only a few locations.  This change
is not supposed to affect the way the values are computed, only
where they live.

* dbxread.c (struct symloc): Add `textlow' and `texthigh' fields
to the reader-specific structure.
* mdebugread.c (struct symloc): Same.
* dbxread.c (TEXTLOW, TEXTHIGH): New accessor macros.
* mdebugread.c (TEXTLOW, TEXTHIGH): Same.
* dbxread.c (dbx_symfile_read): After we've built all our partial
symbol tables, set each partial symtab's `textlow' and `texthigh'
fields from our reader-specific structure.
* mdebugread.c (mdebug_build_psymtabs): Same.
* dbxread.c (start_psymtab): Initialize the reader-specific
structure's `textlow' and `texthigh' from the new psymtab's.
* mdebugread.c (parse_partial_symbols, new_psymtab): Same.
* dbxread.c (read_dbx_symtab, end_psymtab, read_ofile_symtab): Use
the reader-specific `textlow' and `texthigh', not the generic
psymtab fields.
* mdebugread.c (parse_lines, parse_partial_symbols,
psymtab_to_symtab_1): Same.
* partial-stab.h: Same.

Andrew Cagney 4dbdbfc4d3 o Fix code deleting psymtab entry from objfile's list.
Only worked if the first element in the list was
	being deleted.
o	When MAINLINE (reading main objectfile and need to
	clear out old data), change elfread.c so that the
	psymbol table is emptied once (in elf_symfile_read)
	instead of multiple times in each *_read_psymtab
	function.
o	For elf_symfile_read, load dwarf2 symbols last
	(so that they are searched for first).
o	In mdebug_psymtab_read, delete check to see if
	symbols for current source file already loaded.
	Test doesn't work for .h files.  Above change
	works better

Thu Jul 25 19:41:31 1996  Fred Fish  <fnf@cygnus.com>

for a rather huge set of changes.  I was going to put them here, but it
made cvs dump core.  :-(

Stu Grossman 3a179be149 * Makefile.in (os9kread.o): Remove dependency on partial-stab.h.
* dbxread.c (read_dbx_symtab end_psymtab), partial-stab.h:  Don't
	use partial_symtab->textlow==0 as a flag, as 0 is a legitimate

Fred Fish 9391c9977e Changes from: David Mosberger-Tang <davidm@azstarnet.com>
* NEWS:  Add Alpha Linux as a new native configuration.

	* mdebugread.c (parse_symbol): When we find a malloc() symbol with
 	return type VOID, assume no debugging info is available for that
 	object file and patch the return value into VOID *.  Otherwise,
	operations requiring an implicit call to malloc() will fail.

	* infrun.c (wait_for_inferior): The criterion to detect entering a
 	sigtramp handler is now: (a) the current pc is inside a sigtramp
 	handler, (b) the previous pc is not in a sigtramp handler, and (c)
 	the current stack pointer is "inner" than the old one.  Condition
	(c) is new to avoid mistaking a return from a signal handler into
 	sigtramp as a new sigtramp invocation.

	* dcache.c (struct dcache_block): Declare addr as CORE_ADDR.  An
 	int may not be big enough to hold an address.
	(dcache_hit): Ditto.
	(dcache_peek_byte): Fix indentation.

	* configure.in (alpha-*-linux*): Add target.
	* configure: Rebuild

	* config/alpha/tm-alpha.h (PROC_DESC_IS_DYN_SIGTRAMP): New macro.
	(SET_PROC_DESC_IS_DYN_SIGTRAMP): Ditto.
	(DYNAMIC_SIGTRAMP_OFFSET): Ditto.
	(SIGCONTEXT_ADDR): Ditto.
	(FRAME_PAST_SIGTRAMP_FRAME): Ditto.

	* config/alpha/alpha-linux.mh: New file.
	* config/alpha/alpha-linux.mt: Ditto.
	* config/alpha/nm-linux.h: Ditto.
	* config/alpha/tm-alphalinux.h: Ditto.
	* config/alpha/xm-alphalinux.h: Ditto.
	* config/alpha/xm-alphaosf.h: Renamed from xm-alpha.h.
	* config/alpha/alpha-osf1.mh (XM_FILE): Change from xm-alpha.h to
 	xm-alphaosf.h.
	* config/alpha/alpha-osf2.mh: Ditto.

	* blockframe.c (find_pc_partial_function): Pass PC to
 	SIGTRAMP_START and SIGTRAMP_END macros for the benefit of systems
 	that detect sigtramp code via designated code sequences (as is the
 	case for Linux/Alpha, for example).

	* config/i386/tm-i386bsd.h: Change SIGTRAMP_START and SIGTRAMP_END
	to ignore new PC argument.
	* config/m68k/tm-hp300bsd.h: Ditto.
	* config/vax/tm-vax.h: Ditto.

	* alpha-tdep.c (alpha_linux_sigtramp_offset): New function.
	(alpha_osf_skip_sigtramp_frame): Ditto.
	(push_sigtramp_desc): Ditto.
	(alpha_find_saved_regs): Use SIGCONTEXT_ADDR macro to extract
 	sigcontext address from frame.
	(alpha_saved_pc_after_call): When in sigtramp, use
 	alpha_frame_saved_pc() instead of read-register().
	(after_prologue): When inside a dynamically generated sigtramp
 	function, there is no prologue, so return address of first
 	instruction.
	(alpha_in_prologue): Fix typo in comment.
	(find_proc_desc): Use macro DYNAMIC_SIGTRAMP_OFFSET to determine
 	whether we're inside a dynamicaly generated sigtramp function.  If
 	so, create and push and appropriate procedure descriptor.
	(alpha_frame_chain): Use macro FRAME_PAST_SIGTRAMP_FRAME to obtain
 	the frame past a sigtramp frame (if the current frame is indeed a
 	sigtramp function).
	(init_extra_frame_info): Don't read next frame register off of
 	stack-pointer when inside a dynamiccaly generated sigtramp.
	(alpha_pop_frame): Also unlink and destroy procedure descriptors
 	created for dynamically generated sigtramp functions.

	* alpha-nat.c: When compiling under Linux, include <asm/reg.h> and
 	<alpha/ptrace.h> instead of <machine/reg.h>
1996-05-26 21:41:40 +00:00
Fred Fish eae8aa302e * symfile.c (INLINE_ADD_PSYMBOL): Remove ifdef.

	gaps due to alignment of structure members.
	* symfile.h (INLINE_ADD_PSYMBOL, ADD_PSYMBOL_TO_LIST,
 	ADD_PSYMBOL_ADDR_TO_LIST): Remove.  Real world tests show no
	performance improvements by inlining via complicated macros and
	they just make gdb larger and harder to maintain.
	* dwarfread.c (add_enum_psymbol): Replace ADD_PSYMBOL_TO_LIST
	and/or ADD_PSYMBOL_ADDR_TO_LIST macro(s) with call to
	add_psymbol_to_list with appropriate long or CORE_ADDR args.
