f977e865cb * som.c (som_get_section_contents): New function. Do not try
to actually read data from a section that doesn't have either
        SEC_LOAD or SEC_DEBUGGING set (eg $BSS$) just return true.
1994-03-26 20:25:48 +00:00
David MacKenzie
9336e47ee2 * configure: Make unrecognized options give nonfatal warnings
instead of fatal errors, and pass them to any subdirectory
	configures in case they recognize them.
	Make --x equivalent to --with-x.

Jeff Law
250578363e * libbfd.c (bfd_read): Set bfd_error as appropriate for a short
read. (bfd_error_system_call or bfd_error_file_truncated).

        * som.c: Do not blindly set bfd_error_system_call after a
        failing bfd_read, bfd_write, or bfd_seek.  In a few places
        (like som_object_p) override the error status set by bfd_read.

        * aix386-core.c, aout-encap,c archive.c, bout.c: Likewise.
        * coff-rs6000.c, coffgen.c ecoff.c, elf.c: Likewise.
        * elf32-hppa.c, elfcode.h, hp300hpux.c, i386lynx.c: Likewise.
        * nlm32-alpha.c, nlm32-i386.c, nlm32-sparc.c: Likewise.

        * som.c: Check return values from several bfd_{seek,read,write}
        calls that we just assumed were not failing.

bb6247c6b2 * buildsym.c (start_subfile, patch_subfile_names), demangle.c
(set_demangling_style, set_demangling_command): Use savestring not
	strdup.  We were not dealing properly with a NULL return from
	strdup, and were not declaring strdup (the system header may or
	may not have it).

of a function.
        (skip_trampoline_code): Rewrite and add support for argument

1994-03-26 01:07:36 +00:00
Jeff Law
277c24a1f0 * gdbme.c (call_with_trampolines): New function to try and step

645f842c99 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.

5b63f465fc * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
branch with an instruction that uses $at, in case the branch is
	later expanded.
	(macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
	(md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
	to make it pcrel_offset.
	(tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
	reloc->address; another gruesome hack to get gas reloc handling to
	do the right thing.

a3a33af390 Changes to support linker relaxing of embedded MIPS PIC code to
use a five instruction sequence for funtion calls which are out of
	range of the bal instruction.
	* libecoff.h (struct ecoff_section_tdata): Define.
	(ecoff_section_data): Define.
	(ecoff_bfd_relax_section): Don't define.
	* ecoff.c (ecoff_final_link_debug_accumulate): Don't read or free
	the debugging information if it has already been read.
	(ecoff_indirect_link_order): Handle _cooked_size being different
	from _raw_size.  Don't reread the contents or the relocs if they
	have already been read in.
	* coff-mips.c (mips_howto_table): Change bitsize of PCREL16 from
	18 to 16.
	(PCREL16_EXPANSION_ADJUSTMENT): Define.
	(mips_relocate_refhi): Take adjust argument.
	(mips_relocate_section): Handle reloc offsets stored in section
	used_by_bfd field.  Call mips_relax_pcrel16 to handle details of
	expanding an out of range PCREL16.  Keep trace of adjustments
	required by expansions.  Set s and unset h when converting a reloc
	from undefined to section.  Change handling of PC relative relocs:
	if against a section, they are correct in the object file, if
	against an external symbol they are pcrel_offset.
	(mips_relax_section): New function.
	(mips_relax_pcrel16): New function.
	(ecoff_bfd_relax_section): Define.
	* coff-alpha.c (ecoff_bfd_relax_section): Define.

ec099b4b25 * aoutx.h (NAME(aout,find_nearest_line)): The caller expects
functionname_ptr to be set to a symbol name, so prepend
	symbol_leading_char.

(REGISTER_NAMES): Add entries for "right-half" of FP registers.
        (REGISTER_RAW_SIZE, MAX_REGISTER_RAW_SIZE): Do not treat FP regs
        differently.  All registers are four bytes.
        (REGISTER_BYTES, REGISTER_BYTE): Simplify now that all registers are
        the same size.
        (REGISTER_VIRTUAL_TYPE): Use builtin_type_float for all FP regs.

        * hppa-tdep.c (pa_print_fp_reg): Update to print even numbered FP
        registers as both single and double values (fetching 2nd 32bit half
        as necessary).  Annotate each register printed with its precision.

(emit_insn): New function.
(md_assemble): Call it.
(alpha_force_relocation): Handle BFD_RELOC_26, for call_pal instructions.
(lituse_pending): New variable.  Set by anything that generates a LITERAL
reloc, cleared by anything that generates a LITUSE reloc, tested by code that
might want to emit a LITUSE reloc.
(emit_unaligned_io): New function.  Currently calls md_assemble, but it should
eventually be converted to generate the insn itself and call emit_insn directly.
(emit_load_unal, emit_store_unal, emit_byte_manip_r, emit_extract_r,
emit_insert_r, emit_mask_r, emit_sign_extend, emit_bis_r): Likewise.
(alpha_ip, case 'I'): Handle with BFD_RELOC_23.
(alpha_ip, label get_macro): Don't emit the final instruction if the opcode is
zero.
(alpha_ip, case 'B', subcase 'd'): New case, for subword and unaligned memory
access macros.
(md_apply_fix): Handle BFD_RELOC_26.  Generate an error message if the value
can't be resolved.

Jim Kingdon
4df6dcd10d * config/mips/tm-mips.h (SETUP_ARBITRARY_FRAME): Revise comment
regarding using the PC--using the PC is necessary and all the
	FIXME comments in the world won't make it go away.

193c5f93a1 * ldlang.c (new_afile): Add new argument add_to_list. Don't set
real to true for lang_input_file_is_marker_enum.  Clear the_bfd.
	(lang_add_input_file): Pass true to new_afile for add_to_list.
	(lookup_name): Remove force_load argument.  Changed all callers.
	Pass false to new_afile for add_to_list.  Split loading of symbols
	out into separate function.
	(load_symbols): New function split out of lookup_name.  Don't load
	the symbols if they are already loaded.
	(open_input_bfds): For lang_input_statement_enum call load_symbols
	rather than lookup_name.
	(lang_process): Pass abs_output_section rather than NULL to
	lang_size_sections.
	(lang_startup): Set real field of first_file to true.
