moved into hppa-tdep.c.
(read_unwind_info): Likewise.
(pa_symfile_read): No longer call read_unwind_info. The unwind
tables will be read in as they are needed.
* hppa-tdep.c (compare_unwind_entries): New function.
(read_unwind_info, internalize_unwinds): Likewise.
(find_unwind_entry): Read in unwind information on demand.
* paread.c (pa_symtab_read): Update the "check_strange_names"
filter to match GCC's current output. Filter out section symbols
(which the HP linker sometimes puts in the wrong place).
not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
the HP compiler in ANSI mode doesn't like.
* main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
based on USG, rather than defining HAVE_SIGSETMASK to an expression
containing defined. This is for the HP compiler in ANSI mode.
reserved fields to hold a stub unwind entry type. Fix typo.
(stub_unwind_entry): New structure for raw stub unwind entries.
(stub_unwind_types): The types of stubs we may encounter.
(UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.
* hppa-tdep.c (rp_saved): Use additional information provided
by linker stub unwind descriptors.
(frameless_function_invocation): Likewise.
(frame_chain_valid): Likewise.
* paread.c (compare_unwind_entries): New function for sorting
unwind table entries.
(read_unwind_info): Rewrite to remove dependency on host endianness.
Read in data from the $UNWIND_END$ subspace which contains linker
stub unwind descriptors. Merge that data into the basic unwind
table.
right operations ourself, rather than calling symbol_file_command.
If we re-read something, call clear_symtab_users not just
breakpoint_re_set.
* objfiles.h, objfiles.c (build_objfile_section_table): No longer
static.
* symfile.c (clear_symtab_users): Call clear_pc_function_cache.
* coffread.c, dbxread.c, elfread.c, mipsread.c, nlmread.c, paread.c
(*_symfile_offsets): Set objfile->num_sections.
* remote.c (remote_wait), symfile.c (syms_from_objfile):
Don't muck with objfile->num_sections now that all the symbol
readers set it.
* elfread.c: Clean up obsolete comment about handling only DWARF.
* paread.c: Remove comment about how we should use an "ordinary"
file format with an hppa suffix. There is nothing ordinary about SOM.
* stabsread.h: Group together dbxread.c functions.
Move elfstab_build_psymtabs here from symfile.h.
Declare pastab_build_psymtabs.
* elfread.c, paread.c: Include stabsread.h (for stabsread_new_init
declaration, etc).
read_memory to get byte order right.
* hppah-tdep.c (find_unwind_info): Don't read in unwind info
anymore. This is done in paread.c now. We expect unwind info
to hang off of objfiles, and search all of the objfiles when until
we find a match.
* (skip_trampoline_code): Cast arg to target_read_memory.
* objfiles.h (struct objfile): Add new field obj_private to hold
per object file private data (unwind info in this case).
* paread.c (read_unwind_info): New routine to read unwind info
for the objfile. This data is hung off of obj_private.
* tm-hppa.h: Define struct obj_unwind_info, to hold pointers to
the unwind info for this objfile. Also define OBJ_UNWIND_INFO to
make this easier to access.
comment.
* gdbtypes.h, gdbtypes.c: Use const in decl of
cplus_struct_default, now that pa-gas assembler has been fixed.
* hppah-nat.c: Formatting.
* hppah-tdep.c: Remove lots of useless externs for variables we
don't use.
* (find_unwind_entry): Speed up by using binary search, and a one
entry cache.
* (rp_saved): New routine to see what unwind info says about RP
being saved on the stack frame.
* (frame_saved_pc): Look for prologue to see if we need to
examine the stack for the saved RP or not.
* (init_extra_frame_info): Check for prologue, instead of
framesize to determine if we are frameless or not.
* (frame_chain_valid): Stop backtraces when we run into _start.
* (push_dummy_frame): Reformat to make more readable.
* (find_dummy_frame_regs): ditto.
* (hp_pop_frame): ditto.
* (hp_restore_pc_queue): small cleanup.
* (hp_push_arguments): ditto.
* (pa_do_registers_info): ditto.
* (skip_prologue): New routine created from SKIP_PROLOGUE macro.
* tm-hppa.h: Move contents of SKIP_PROLOGUE into hppah-tdep.c.
* Define FRAME_CHAIN_VALID.
* Turn on BELIEVE_PCC_PROMOTION so that we can access char args
passed to functions.
* paread.c (pa_symtab_read): Use new bfd conventions for
accessing linker symbol table.
* (pa_symfile_init): Access embedded STAB info via BFD section
mechanism and related macros.
code.
* dbxread.c: Remove almost all HPPA/HPUX symbol reading code.
* (dbx_symfile_init): Use sizeof(long) instead of 4.
* (dbx_symfile_offsets): Make static.
* (pastab_build_psymtabs): New interface routine for paread to
send stabs into dbxread.
* gdb-stabs.h: Remove gobs of HPPA cruft.
