* obj-coffbfd.h (TARGET_FORMAT) [TC_I960]: Ditto. * obj-coff.c (coff_frob_section): Round up the size of every section to a multiple of the alignment, so that BFD doesn't surprise us. Eliminate many simple differences between the two COFF back ends: * obj-coffbfd.c: Removed all uses of DEFUN and DEFUN_VOID. Made minor stylistic changes, deleted some register declarations. (stack_top): Deleted. (symbol_to_chars): Use absolute_section and reg_section instead of the corresponding SEG_* symbols. (obj_coff_endef, tag_find_or_make, fixup_segment): Likewise. (stack typedef, stack_init, stack_delete, stack_push, stack_pop): Moved to just after pseudo-op table. All functions now static. (stack_delete): Removed declaration. (tag_init, tag_insert, tag_find_or_make, tag_find): Moved to just after stack functions. * obj-coffbfd.h: Reordered some declarations and macros. (stack_init, stack_delete, stack_push, stack_pop): Don't declare. (stack typedef): Deleted. (SYMBOLS_NEED_BACKPOINTERS): Always undef then define; don't test. (SYM_AUXENT): New macro. (SA_GET_*, SA_SET_*): Define in terms of SYM_AUXENT when feasible. (SF_GET_*, SF_SET_*): Define in terms of SF_GET when feasible. (SA_GET_SYM_TAGNDX, SA_GET_SYM_ENDNDX, SA_SET_SYM_TAGNDX, SA_SET_SYM_ENDNDX, object_headers typedef, data_section_header, text_section_header): Delete non-BFD_HEADERS versions, since we always define that symbol now. * obj-coff.c (stack_top): Deleted. (obj_coff_endef, obj_coff_dim, obj_coff_line, obj_coff_size, obj_coff_scl, obj_coff_tag, obj_coff_type, obj_coff_val): Change argument name from "ignored" to "ignore". (obj_coff_val): Use frag_now_fix. (obj_pseudo_table): Removed IGNORE_DEBUG version, since it doesn't get used. (stack typedef, stack_init, stack_delete, stack_push, stack_pop): Moved to just after pseudo-op table. All functions now static. (tag_init, tag_insert, tag_find_or_make, tag_find): Moved to just after stack functions. * obj-coff.h: Reordered some declarations and macros. Protected against multiple inclusions. (stack_init, stack_delete, stack_push, stack_pop): Don't declare. (stack typedef): Deleted. (SYMBOLS_NEED_BACKPOINTERS): Always undef then define; don't test. (stdoutput): Deleted declaration. (TARGET_FORMAT) [TC_I386]: Don't define if already defined.
