ecoff_swap_rndx_out, ecoff_swap_rfd_out, ecoff_swap_opt_in,
ecoff_swap_opt_out, ecoff_swap_dnr_in, ecoff_swap_dnr_out): New
functions.
* coffswap.h: If NO_COFF_RELOCS is defined, don't define
bfd_swap_reloc_in or coff_swap_reloc_out.
* coff-mips.c: Added code to link and write out symbolic debugging
information, and to swap relocs in and out.
* ecoff-ext.h: Added prototypes for new ECOFF swapping functions.
(opt_ext): New structure.
* mips.h (ZMAGIC): Defined to be 0413.
(_LIB): Defined to be ".lib"
(external_reloc): MIPS ECOFF relocs are only 8 bytes. Added
macros to aid in swapping.
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.
(coff_write_object_contents): coff_count_linenumbers returns the
number of line number records it found.
* coffgen.c (coff_write_linenumbers): only write out line numbers
in the section they belong to.
* c-valprint.c (c_val_print): Extract code for printing methods
and move it to cp_print_class_method in cp-valprint.c.
* c-valprint.c (c_val_print): Extract code to print strings and
move it to val_print_string in valprint.c.
* cp-valprint.c (cp_print_class_method): New function using
code extracted from c_val_print.
* valprint.c (val_print_string): New function using code
extracted from c_val_print.
* value.h (val_print_string): Add prototype.
**** start-sanitize-chill ****
* ch-exp.y (CHARACTER_STRING_LITERAL): Set correct token type.
* ch-exp.y (literal): Add action for CHARACTER_STRING_LITERAL.
* ch-exp.y (tempbuf, tempbufsize, tempbufindex, GROWBY_MIN_SIZE,
CHECKBUF, growbuf_by_size): New variables, macros, and support
functions for implementing a dynamically expandable temp buffer.
* ch-exp.y (match_string_literal): New lexer function.
* ch-exp.y (match_bitstring_literal): Dynamic buffer code
removed and replaced with new CHECKBUF macro.
* ch-exp.y (yylex): Call match_string_literal when appropriate.
* ch-valprint.c (ch_val_print): Add code for TYPE_CODE_PTR.
**** end-sanitize-chill ****
* ldwrite.c: Removed perform_relocation, copy_and_relocate, and
write_norel. All linking is now done via write_relax. Call
ldsym_write before calling write_relax.
* relax.c: Added copyright.
(write_relax): Renamed from write_relaxnorel. Added relocateable
argument. seclet_dump renamed to bfd_seclet_link.
* relax.h: Added copyright.
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.
debug info. Setup info about linker symbols only, and use
standard bfd fields to hold the info.
* (hppa_object_p): Remove unneeded decls.
* (hppa_new_section_hook): Get rid of most of this.
* libhppa.h (struct hppadata): Remove ten pounds of useless ugly
fat. Remove all knowledge of stabs, remove redundant knowledge of
linker symbols.
* Remove macros for accessing fields which are now gone.
* Handle recursive traps.
* Remove all trap init code. This needs to be done by the
environment.
* (set_mem_fault_trap): Call exceptionHandler() to setup this
trap.
* (handle_exception): See if we are at breakinst, if so, then
advance PC sp that users can just step out of breakpoint().
* (case 'G'): Don't let GDB hack CWP. Also, copy saved regs to
new place if SP has changed.
* (case 's'): Get rid of this, we can't do it yet.
* (case 't'): New command to test any old random feature.
* (case 'r'): New command to reset the system.
* (breakpoint): Add label to breakpoint trap instruction so that
handle_exception() can detect where we are and get past the
breakpoint trivially.
Fri Jan 8 15:47:53 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* bfd.c (struct _bfd): Added ecoff_tdata to tdata union.
* targets.c (enum target_flavour): Added bfd_target_ecoff_flavour.
* coff-msym.c: Use DEFUN for function definitons.
* coff-mips.c: Added code to read and print symbols, and to find
line numbers.
* ecoff-ext.h: Added prototypes for ECOFF swapping functions.
* internal.h (internal_scnhdr): Always provide s_align field, not
just on i960.
(internal_reloc): Always provide r_size field, not just on
RS/6000.
* mips.h (_RDATA, _SDATA, _SBSS, _LIT4, _LIT8, STYP_RDATA,
STYP_SDATA, STYP_SBSS, STYP_LIT4, STYP_LIT8): Defined.
(CODE_MASK, MIPS_IS_STAB, MIPS_MARK_STAB, MIPS_UNMARK_STAB,
STABS_SYMBOL): Moved in from gdb/mipsread.c.
Somewhat more could be done.
Fri Jan 8 15:47:53 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* coffcode.h: Moved many generic functions into coffgen.c. Moved
swapping functions into coffswap.h for ECOFF use. Moved
relocation functions, only used by h8300 and z8k, into reloc16.c.
Added hooks for coffgen.c functions to backend data structure, and
added hook functions. Still more could be done.
* coffswap.h: New file to hold COFF swapping routines.
* coffgen.c: New file to hold generic COFF functions.
* reloc16.c: New file to hold h8300 and z8k specific relocation
functions.
* libcoff-in.h: Added declarations for functions in coffgen.c.
* libcoff.h: Rebuilt to incorporate changes.
* coff-h8300.c: Function name changes.
* coff-z8k.c: Function name changes. Use coff_reloc16_extra_cases
hook rather than defining EXTRA_CASES.
* Makefile.in: Build new files coffgen and reloc16. Added
dependencies of coff-*.o on coffswap.h and seclet.h.
by configure, using configure.in .
**** start-sanitize-chill ****
* configure.in: Added sanitization for chill to the setting of
target_libs .
**** end-sanitize-chill ****
