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.
