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

* 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.

* 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>

(add_psymbol_to_list): Add an arg for passing CORE_ADDR values and
use it, rather than calling add_psymbol_addr_to_list.
(add_psymbol_addr_to_list): Delete.
(add_psymbol_to_list): Make psymbol static to avoid random data in
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.

with CPLUS_MARKER.

callers/references changed.
* dbxread.c (read_ofile_symtab): Correctly determine value for
last_source_start_addr for reordered executables.
(process_one_symbol): Handle N_FUN with no name as an end of
function marker.
* partial-stab.h (case N_FN, N_TEXT): Don't assume CUR_SYMBOL_VALUE
is the high text address for a psymtab.
(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.
* somread.c (som_symfile_init): Similarly.
* xcoffread.c (xcoff_symfile_init): Similarly.
Support for debugging reordered executables. Remaining mentor vm
changes.

Also update copyright to 1995.
