Breaks with the HP compilers.
* config/tc-hppa.c (struct call_info): Remove fields which were
set but never used. Remove all code which sets those fields.
(struct subspace_dictionary_chain): Likewise.
(struct space_dictionary_chain): Likewise.
(pa_desc): Delete useless function. Delete all references.
(hppa_tc_make_sections): No need to count the number of symbols for
the symbol extension section.
SOM BFD backend.
(obj_som_copyright): New function. Much like obj_som_version.
* config/tc-hppa.c (obj_copyright): Define as appropriate for
SOM and ELF.
(pa_copyright): Just a stub now.
* tc-hppa.c: (tc_gen_reloc): Addend for a plabel relocation should
be either 0 or 2 (no static link or static link required). Always
assume no static link.
(md_apply_fix_1): Rename to md_apply_fix. Fix argument decls.
Fix comments in various places. Always return a value.
Avoid dereferencing a NULL fx_addsy.
(hppa_force_relocation): Avoid dereferencing a NULL fx_addsy.
- sparc[lite]-coff as well as sparc-lynx
- producing coff (including debug info) under BFD_ASSEMBLER option
- cleanup of cpu-specific code in non-cpu-specific files
(especially write.c)
- providing common code to avoid duplication in cpu-specific files
(specifically, md_number_to_chars)
- stylistic changes & misc cleanup
================
* config/tc-sparc.c (tc_gen_reloc): Make adjustment to addend be dependent on
howto fields, not on format flavour.
* struc-symbol.h (struct symbol): New fields sy_obj and sy_tc, defined as types
OBJ_SYMFIELD_TYPE and TC_SYMFIELD_TYPE, if those macros are defined.
* config/obj-coff.h (TC_SYMFIELD_TYPE, OBJ_SYMFIELD_TYPE): Define.
(TARGET_SYMBOL_FIELDS, I960_SYM_FIELDS): Don't define.
(sy_tc, sy_obj): Define so that the fields look like they used to, until all
references get changed.
* write.c (fixup_segment): Lots of variables no longer register. Reordered
some code for easier reading.
* config/obj-coff.c (obj_coff_dim): dim_index no longer register. Deleted
superfluous return statement.
(obj_coff_line, obj_coff_size, obj_coff_scl, obj_coff_type, obj_coff_val,
tag_init, tag_insert): Deleted superfluous return statement.
(align, obj_coff_section): Deleted debugging printfs.
* config/tc-i386.c (md_assemble): Discard some register decls. Use assignment
rather than memcpy to copy template.
(op_hash, reg_hash, prefix_hash): Default C initialization of statics is
sufficient.
* config/tc-sparc.c (print_insn): Array Reloc is now const, and points to
const.
* config/obj-coff.h (TARGET_FORMAT): Only use coff-sparc-lynx if TE_LYNX; use
coff-sparc otherwise.
[USE_NATIVE_HEADERS]: Delete this code; it isn't used.
* write.c (fixup_segment): Call TC_VALIDATE_FIX, if defined, before processing
a fixup. Call TC_ADJUST_RELOC_COUNT just before returning. Remove some
i960-coff-specific code.
(TC_ADJUST_RELOC_COUNT): Default to doing nothing.
* config/tc-i960.h (TC_ADJUST_RELOC_COUNT) [OBJ_COFF]: Define.
(i960_validate_fix): Declare.
(TC_VALIDATE_FIX): Define.
* config/tc-i960.c (i960_validate_fix): New function.
* write.c (number_to_chars_littleendian): New function. Write out bytes in
little endian order, doing size and range checking.
(number_to_chars_bigendian): New function, similar.
* write.h: Declare them.
* config/tc-*.c (md_number_to_chars): Use them.
* config/tc-vax.c (md_apply_fix): Ditto.
* config/tc-i386.c (md_apply_fix): Ditto.
* config/obj-coff.c: Rearranged code for handling line number data.
(line_fsym): Renamed from function_lineoff in BFD_ASSEMBLER case, since the
usage is different from non-BFD_ASSEMBLER case.
(in_function, clear_function, set_function): New macros, to combine some of the
functionality implemented in differnet ways in BFD_ASSEMBLER and non-... code.
Used in other functions that used to check function_lineoff &c.
(obj_emit_lineno): Split into two copies, one for BFD_ASSEMBLER, one for not.
Non-BFD_ASSEMBLER version now has temporary variable to contain char* pointer
pointed to by char** argument. Always follow CROSS_COMPILE code; easier to
read that way.
(obj_coff_ln): Don't call add_lineno or c_line_new if appline is set.
(obj_coff_endef) [BFD_ASSEMBLER]: Don't do anything special for ".bf", it's
been done elsewhere.
(coff_frob_symbol): If ilne number data is pending, call add_linesym to flush it.
(coff_frob_file): Don't do that here.
* config/obj-coff.h (coff_frob_file): Declare.
(obj_frob_file): Define, to call it.
* config/tc-sparc.h (md_create_short_jump, md_create_long_jump,
md_estimate_size_before_relax: Define them as macros calling as_fatal.
* config/tc-sparc.c: Don't define them as functions.
(fixup_segment): Allow the target machine to specify that a
relocation must be generated for a particular fixup. Remove
#ifndef TC_HPPA hack.
* config/tc-hppa.h (TC_FORCE_RELOCATION): Define.
* config/tc-hppa.c (md_apply_fix_1): Never change fx_addsy to
be NULL. Only fixup_segment is supposed to do that.
(hppa_force_relocation): New function.
exists before trying to peek at its name.
(pa_space): Do not call pa_align_subseg. See hppa/unsorted/align3.s
for testcase.
(pa_align_subseg): Delete unused/unwanted function.
on the end of a label. Make code conditional on either MRI or
LABELS_WITHOUT_COLONS.
* app.c (do_scrub_next_char): If a line begins with whitespace, leave
the single whitespace character alone. Eat all others.
* config/tc-hppa.h (LABELS_WITHOUT_COLONS): Define.
Changed to not actually build the external symbol information, as
that is now done by the ECOFF back end.
(ecoff_build_debug): Changed accordingly.
* ecoff.h (obj_ecoff_set_ext): Declare. obj-format.c function
called by ecoff_setup_ext.
* config/obj-ecoff.c (ecoff_frob_file): If debug_info count is 0,
set corresponding pointer to NULL. Don't set raw_size and
raw_syments.
(obj_ecoff_set_sym_index): Removed.
(obj_ecoff_set_ext): New function.
* config/obj-ecoff.h (obj_set_sym_index): Don't define.
(obj_ecoff_set_sym_index): Don't declare.
* config/obj-elf.c (obj_ecoff_set_ext, elf_get_extr,
elf_set_index): New functions used for ECOFF_DEBUGGING.
(elf_frob_file): Reworked ECOFF debug generation to use
new functions in bfd/ecofflink.c.
field selector, rather than an int. All uses of field selectors
fixed.
(tc_gen_reloc): For SOM PLABELs, always set addend to zero for now.
(md_apply_fix_1): Do not call hppa_field_adjust for any PLABEL
field.
Accept new argument "is_export". All callers changed. When
processing a .export directive for a function, do not allow
the user to set the type to "CODE", instead warn and set the
type to "ENTRY".
