Do generic rs_machine_dependent relaxation only if TC_GENERIC_RELAX_TABLE is
defined. Use its value as the base of the table, so the actual declaration
can be cpu-specific (and const or not as appropriate). For other cpus where
this isn't done (the majority), delete md_relax_table altogether.
For machines with WORKING_DOT_WORD, delete md_{short,long}_jump_size.
* tc.h (md_end): Don't declare it.
* config/tc-*.[ch] (md_end): Deleted, in cases where it doesn't do anything.
* config/tc-vax.c (vip_end): Deleted null function.
* config/tc-mips.c (md_mips_end): Renamed from md_end.
* config/tc-mips.h (md_mips_end): Declare.
(md_end): New macro, calls md_mips_end.
* write.c (write_object_file): Don't close output file.
* as.c (main): Close output file (if needed) after calling listing_print, which
should be after calling write_object_file, which sets the frag addresses.
const.
* config/obj-*.c, config/tc-*.c: Omit superfluous "return" statements at ends
of functions. Don't check for null return from hash_new, since it won't return
at all if there's no memory available. Also, check for null return from
hash_insert, rather than zero-length string, as success indicator.
- 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.
