+       Add support for macros.
+       * as.c: Include sb.h and macro.h.
+       (max_macro_next): New global variable.
+       (main): Call macro_init.
+       (macro_expr): New static function.
+       * as.h (max_macro_nest): Declare.
+       * read.c (line_label): Rename from mri_line_label.  Change all
+       uses.
+       (potable): Add exitm, irp, irpc, macro, mexit, rept.
+       (read_a_source_file): Always clear line_label at the start of a
+       line, not just when flag_mri or LABELS_WITHOUT_COLONS.  Fixup
+       MRI/LABELS_WITHOUT_COLONS handling.  In MRI mode, permit label:
+       equ val.  Set line_label when calling colon.  In MRI mode, a
+       leading '.' does not imply a pseudo-op.  Check for macro expansion
+       before calling md_assemble.
+       (s_irp): New function.
+       (get_line_sb): New static function.
+       (s_macro): New function.
+       (s_mexit): New function.
+       (s_rept): New function.
+       * read.h (line_label): Rename from mri_line_label.
+       (s_irp, s_rept): Declare.
+       (s_macro, s_mexit): Declare.
+       * input-scrub.c: Include sb.h.
+       (sb_index, from_sb): New static variables.
+       (macro_nest): New static variable.
+       (struct input_save): Add sb_index and from_sb fields.  Change
+       next_saved_file field to be struct input_save *.
+       (next_saved_file): Changed to be struct input_save *.
+       (input_scrub_push): Change to return type struct input_save *.
+       Save sb_index and from_sb.
+       (input_scrub_pop): Change parameter type to struct input_save *.
+       Restore sb_index and from_sb.
+       (input_scrub_include_sb): New function.
+       (input_scrub_next_buffer): Handle reading from from_sb.
+       (bump_line_counters): Only increment lines if not using from_sb.
+       * config/tc-m68k.c (opt_table): Add nest.
+       (opt_nest): New static function.
+       * gasp.c: Include sb.h and macro.h.  Move all sb related functions
+       and definitions to sb.h and sb.c.  Move all macro related
+       functions and definitions to macro.h and macro.c.
+       * sb.h, sb.c: New files, extracted from gasp.c.
+       * macro.h, macro.c: Likewise.
+       * Makefile.in (OBJS): Add sb.o and macro.o
+       (GASPOBJS): Define.
+       (gasp.new): Depend upon $(GASPOBJS).  Use $(GASPOBJS) to link.
+       (TARG_CPU_DEP_m68k): Depend upon subsegs.h.
+       (gasp.o): Depend upon sb.h and macro.h.
+       (sb.o): New target.
+       (macro.o): New target.
+       (as.o): Depend upon sb.h and macro.h.
+       (input-scrub.o): Depend upon sb.h.
+       (read.o): Depend upon sb.h and macro.h.
+
+       * cond.c (get_mri_string): New static function.
+       (s_ifc): New function.
+       * read.c (potable): Add ifc and ifnc.
+       * read.h (s_ifc): Declare.
+
+       * app.c (do_scrub_begin): In MRI mode, set lex of ' to
+       LEX_IS_STRINGQUOTE.

        * config/tc-ppc.c (md_assemble): Allow @HA, @L, and @H suffixes on
