Fri Sep 10 11:22:08 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* config/obj-elf.h (S_SET_SIZE): Actually set the size.
Gcc lint.
* app.c (do_scrub_begin), as.c (main), expr.c (integer_constant,
operand, expr), read.c (read_begin, HANDLE_CONDITIONAL_ASSEMBLY,
read_a_source_file, s_align_bytes, demand_empty_rest_of_line,
ignore_rest_of_line, big_cons, is_it_end_of_statement, s_ignore),
read.h (is_name_beginner, is_part_of_name), config/obj-elf.c
(obj_elf_section), config/tc-i386.c (parse_register),
config/tc-sparc.c (isoctal, s_proc): Cast char
array indices to unsigned char.
* as.c: Include output-file.h for prototypes. Comment out unused
function got_sig.
* Makefile.in (as.o): Depend on output-file.h.
* as.h (BAD_CASE): Cast val argument to long, and use %ld.
* cond.c (ignore_input): Removed unused local variable ptr.
* frags.h: Add prototype for frag_init.
* listing.c (list_symbol_table): Cast sprintf argument to unsigned
long and use %lx. Print name of segment rather than address of
structure.
* read.h: Change get_absolute_expression prototype to return
offsetT. Add prototype for next_char_of_string.
* read.c: Remove prototype for next_char_of_string.
(s_comm): Change temp from valueT to offsetT. Cast to long when
printing and use %ld (only for error messages anyhow).
(emit_expr): Use %lx when printing longs.
(get_absolute_expression): Return offsetT, not long.
(get_stab_string_offset): Comment out unless
SEPARATE_STAB_SECTIONS.
(s_stab_generic): Remove unused offset. Define seg_is_new only
if SEPARATE_STAB_SECTIONS. Use toP only in local block.
* symbols.c: Remove nested comment.
(colon): Use %ld and cast to long in error message.
* write.c (cvt_frag_to_fill): Change first argument name depending
on BFD_ASSEMBLER.
(write_relocs): Remove unused offset, frags.
(write_contents): Remove unused i, n, relocs, fixp.
(write_object_file): Define fragP only if not BFD_ASSEMBLER or not
WORKING_DOT_WORD. Remove unused keep. Only declare punt and
punt_it if they will be used.
(fixup_segment): Cast to long and use %ld in error message.
* config/obj-aout.h: Remove nested comment. Add prototype for
obj_aout_frob_symbol.
* config/obj-ecoff.c (add_string): Make len unsigned long.
(obj_ecoff_stab): Use %lu in error message.
* config/obj-elf.c (obj_elf_common): Comment out unused label
allocate_bss.
(obj_elf_frob_symbol): Return 0 (currently broken).
* config/tc-hppa.h: Remove declarations of functions declared in
read.h.
* config/tc-mips.c (mips_ip, md_apply_fix): Cast to long and use
%ld in error messages.
* config/tc-sparc.c (getExpression): Rewrite condition to avoid
empty conditional body.
