* stabs.c (s_stab_generic): For PowerPC ELF, allow .stabd to take
4 arguments, providing the 4th argument is 0, to allow
compatibility with the Solaris assembler.
Thu May 16 15:51:48 1996 Ian Lance Taylor <ian@cygnus.com>
* config/tc-sh.h (struct sh_segment_info_type): Define.
(TC_SEGMENT_INFO_TYPE): Define.
(sh_frob_label): Declare.
(tc_frob_label): Define.
(sh_flush_pending_output): Declare.
(md_flush_pending_output): Define.
* config/tc-sh.c (md_assemble): If relaxing, emit a R_SH_CODE
reloc before the instruction if necessary.
(sh_frob_label): New function.
(sh_flush_pending_output): New function.
(sh_coff_frob_file): Ignore ALIGN, CODE, DATA, and LABEL relocs
when looking for the reloc for the target of .uses.
(md_convert_frag): Fix printf format (%0xlx to 0x%lx).
(sh_force_relocation): Force CODE, DATA, and LABEL relocs to be
emitted.
(md_apply_fix): Ignore CODE, DATA, and LABEL relocs.
(sh_coff_reloc_mangle): Force CODE, DATA, and LABEL relocs to use
the absolute symbol.
* subsegs.h (segment_info_type): Add tc_segment_info_data field if
TC_SEGMENT_INFO_TYPE is defined.
