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.

* 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.

* 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.

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.
