Wed Jun 30 06:21:27 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
* write.c (relax_and_size_seg): Always fully process a section.
Section size is last frag's (vm)address plus its size. If no
relocations are present, force SEC_RELOC flag clear.
(dump_section_relocs): New debugging routine.
(adjust_reloc_syms): New routine, broken out from write_contents.
Don't adjust relocs that are already relative to section symbol.
Look for obj_fix_adjustable macro to know what else to skip,
instead of obj_write_symbol. Look for section symbol stored in
section information.
(write_object_file): Map adjust_reloc_syms over all sections.
(write_contents): Clear SEC_RELOC flag if no relocations are
found.
* as.h (__PTR_TO_INT, __INT_TO_PTR): New versions for Saber, to
keep it quiet.

* expr.c (expr_part): Made sanity checks a.out-specific.
(expr): Disabled sanity checks.

section symbol.

field back at gas symbol structure.

doing arithmetic on it.
* subsegs.c (subseg_new_rest): Likewise.
* as.h (frag_now_fix): Likewise.
* config/obj-elf.c (elf_file_symbol): Use subseg_new instead of
calling bfd_make_section_old_way directly, and call subseg_set
instead of subseg_change. Now returns void.
(obj_elf_write_symbol): Only check local symbols for now.
(elf_stab_symbol): Now static and void, and disabled until it
works completely.
(obj_elf_size): For expression values, fail silently for now.
(obj_symbol_new_hook): Do nothing.
* config/tc-sparc.c (tc_gen_reloc): Handle BFD_RELOC_SPARC_WDISP22
relocation.
(s_local) [OBJ_ELF]: New function.
(md_pseudo_table) [OBJ_ELF]: Call it for "local".
(s_common): Rearrange to handle Solaris .common pseudo, which may
sometimes use bss space instead of common.

* config/obj-aout.c (s_sect): Do it here.
* as.h (BAD_CASE): Don't make some lame compilers think we want
substitution inside strings.
* as.c (print_version_id): New function, split off from main.
(main): Call it.
* config/tc-sparc.c (md_parse_option) [OBJ_ELF]: Print version id
for -V. Ignore -Q and -s options for now.

* config/obj-coffbfd.c (fill_section): Don't allow fills backwards.
* config/tc-sh (get_specific, md_convert_frag,
md_estimate_size_before_relax): Add support for rest of opcodes.
* m88k-opcode.h : fixed tiny tiny mistake - xcr was incorrectly
specified, should have both S1 and S2 fields identical
If only finding the problem was as fast as fixing the bug !!!!
Tue Jun 15 16:01:57 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
* write.c (write_contents): Do write out non-loadable sections.

".stab" as section base name.
(obj_elf_xstab): New function, calls obj_elf_stab_generic.
(obj_elf_type): Handle "object". Use bitwise-or to merge in
symbol flags rather than simply replacing, so global/local flags
are preserved.
(obj_elf_ident): Rewrite.
