af473842b9 * mdebugread.c (parse_partial_symbols): If this is an .mdebug
section in an ELF file, override a symbol's ECOFF section with its

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

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>

eae8aa302e * symfile.c (INLINE_ADD_PSYMBOL): Remove ifdef.

	they just make gdb larger and harder to maintain.
	* dwarfread.c (add_enum_psymbol): Replace ADD_PSYMBOL_TO_LIST

        (case N_SO): Likewise.
        (case N_FUN): Handle N_FUN with no name as an end of function
        marker.
        * minsyms.c (lookup_minimal_symbol_by_pc): Examine all symbols
        at the same address rather than a random subset of them.
        * coffread.c (coff_symfile_init): Set OBJF_REORDERED.
        * elfread.c (elf_symfile_init): Similarly.

	* utils.c, defs.h (gdb_print_address): New function.
	* expprint (dump_expression), gdbtypes.h: Use it.
	* breakpoint.c (describe_other_breakpoints),
	symmisc.c (dump_symtab, print_symbol):
	Use filtered not unfiltered I/O.
	(remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
	just run gdb under a debugger for this (and it had problems with
	printing addresses, how to print b->shadow, etc.).
	* buildsym.c (make_blockvector), core.c (memory_error),
	exec.c (print_section_info), maint.c (print_section_table),
	mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
	symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
	Add comments saying code is broken.  Marked with "FIXME-32x64".
	* dbxread.c (process_one_symbol), partial-stab.h (default),
	remote-vx.c (vx_run_files_info):
	Don't cast int being passed to local_hex_string.
	* symmisc.c (print_symbol): Don't cast long being passed to %lx.
	* symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
	only being a long.
	* symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
	and LOC_LOCAL.
	* printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
	* source.c: Include <sys/types.h> regardless of USG.

a8c498978e * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
compiler generated tag names.
	* mdebugread.c (parse_type):  Handle cross references to qualified
	aggregate types.
	* valops.c (value_struct_elt):  Improve error message if the
	address of a method is requested from an object instance.
	* valops.c (search_struct_method):  Make name_matched non-static

to process_one_symbol.
	* symtab.c (find_pc_psymbol):  Search global_psymbols as well to
	avoid caching a bad endaddr in find_pc_partial_function.
