binutils-gdb/gas/config/obj-coff.h
Ken Raeburn 8fb85d50cd * obj-coff.h (TARGET_FORMAT) [TC_I960]: Select little endian version. 
* 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.
