Initial support for MRI style labels and expressions.
* as.h (flag_mri): Declare/define. * as.c (show_usage): Mention -M and its synonym --mri. (parse_args): Add 'M' to std_shortopts. Add "mri" to std_longopts. Set flag_mri if -M is seen. (main): Call parse_args before input_scrub_begin. Call expr_begin. * app.c (do_scrub_begin): Don't set lex for '"' or '\'' in MRI mode. Do set lex for ';', '*', and '!' in MRI mode. (do_scrub_next_char): Remove MRI ifdef in LEX_IS_WHITESPACE case. In MRI mode, keep spaces between labels and colons. Remove MRI ifndef around LEX_IS_ONECHAR_QUOTE case. In MRI mode, don't use '!' or '*' as comment characters even if they are in comment_chars. * read.h (lex_type): No longer const. * read.c: Include libiberty.h. (lex_type): No longer const. (read_begin): In MRI mode, set lex_type of '?' to 3. (potable): Add dc, dc.b, dc.d, dc.l, dc.s, dc.w, dc.x, ds, ds.b, ds.l, ds.w, and xdef. (read_a_source_file): Change LABELS_WITHOUT_COLON ifdef to check for MRI mode at runtime rather than compile time. Handle the EQU pseudo-op in MRI mode. Remove bogus MRI ifdef around done_pseudo. Change NO_PSEUDO_DOT ifdef to also take effect for MRI mode at runtime. (cons): In MRI mode, always call parse_mri_cons rather than TC_PARSE_CONS_EXPRESSION. (parse_mri_cons): Always compile, not just when MRI is defined. Call TC_PARSE_CONS_EXPRESSION, not expression, when the input is not a string constant. Handle A and E modifiers. (float_cons): Accept :xxxx, where the x's are hex digits. * expr.h (operatorT): Add O_eq, O_ne, O_lt, O_le, O_ge, O_gt. (expr_begin): Declare. * expr.c (integer_constant): In MRI mode, if the base was not specified, look for a suffix on the number to set the base. (mri_char_constant): New static function. (operand): Remove MRI ifdef. In MRI mode, do various things: Pass 0 as the base when calling integer_constant if there was no prefix. Check for a hex constant suffix if when a leading '0' is seen. Don't accept 0x or 0b as a prefix. Check for E'chars' and A'chars'. Handle MRI character constants. Treat '"' as the unary bitwise not operator. Treat $ as the program counter, or as the prefix for a hex constant. Treat % as the prefix for a binary constant and @ as the prefix for an octal constant. Treat : as the prefix for a hex constant. (op_encoding): Set '"' to O_bit_not, '<' to O_lt, and '>' to O_gt. (op_rank): No longer const. Change rank values. (expr_begin): New function. (operator): New static function. (expr): Use operator. Don't bother to mention the operator in warnings. Remove bogus #if 0 code.

(symbol_create): Check symbols_case_sensitive. (symbol_find_base): Likewise. (resolve_symbol_value): Handle new operatorT values. (print_expr_1): Likewise.

* config/tc-m68k.c (init_table): Add "control", "status", "iaddr",
|
||||||
|
"sfcr", and "dfcr" as synonyms for existing entries.
|
||||||
|
(md_begin): In MRI mode, force flag_reg_prefix_optional to 1.
|
||||||
|
(md_parse_option): Removed unused locals i and arch. Change type
|
||||||
|
of arch (another one) to unsigned long.
|
||||||
|
(tc_coff_sizemachdep): Add return after abort to avoid warning.
|

Initial support for MRI style labels and expressions.
|
||||||
|
* as.h (flag_mri): Declare/define.
|
||||||
|
* as.c (show_usage): Mention -M and its synonym --mri.
|
||||||
|
(parse_args): Add 'M' to std_shortopts. Add "mri" to
|
||||||
|
std_longopts. Set flag_mri if -M is seen.
|
||||||
|
(main): Call parse_args before input_scrub_begin. Call
|
||||||
|
expr_begin.
|
||||||
|
* app.c (do_scrub_begin): Don't set lex for '"' or '\'' in MRI
|
||||||
|
mode. Do set lex for ';', '*', and '!' in MRI mode.
|
||||||
|
(do_scrub_next_char): Remove MRI ifdef in LEX_IS_WHITESPACE case.
|
||||||
|
In MRI mode, keep spaces between labels and colons. Remove MRI
|
||||||
|
ifndef around LEX_IS_ONECHAR_QUOTE case. In MRI mode, don't use
|
||||||
|
'!' or '*' as comment characters even if they are in
|
||||||
|
comment_chars.
|
||||||
|
* read.h (lex_type): No longer const.
|
||||||
|
* read.c: Include libiberty.h.
|
||||||
|
(lex_type): No longer const.
|
||||||
|
(read_begin): In MRI mode, set lex_type of '?' to 3.
|
||||||
|
(potable): Add dc, dc.b, dc.d, dc.l, dc.s, dc.w, dc.x, ds, ds.b,
|
||||||
|
ds.l, ds.w, and xdef.
|
||||||
|
(read_a_source_file): Change LABELS_WITHOUT_COLON ifdef to check
|
||||||
|
for MRI mode at runtime rather than compile time. Handle the EQU
|
||||||
|
pseudo-op in MRI mode. Remove bogus MRI ifdef around done_pseudo.
|
||||||
|
Change NO_PSEUDO_DOT ifdef to also take effect for MRI mode at
|
||||||
|
runtime.
|
||||||
|
(cons): In MRI mode, always call parse_mri_cons rather than
|
||||||
|
TC_PARSE_CONS_EXPRESSION.
|
||||||
|
(parse_mri_cons): Always compile, not just when MRI is defined.
|
||||||
|
Call TC_PARSE_CONS_EXPRESSION, not expression, when the input is
|
||||||
|
not a string constant. Handle A and E modifiers.
|
||||||
|
(float_cons): Accept :xxxx, where the x's are hex digits.
|
||||||
|

|
||||||
|
(expr_begin): Declare.
|
||||||
|

|
||||||
|
(mri_char_constant): New static function.
|
||||||
|
(operand): Remove MRI ifdef. In MRI mode, do various things: Pass
|
||||||
|
0 as the base when calling integer_constant if there was no
|
||||||
|
prefix. Check for a hex constant suffix if when a leading '0' is
|
||||||
|
seen. Don't accept 0x or 0b as a prefix. Check for E'chars' and
|
||||||
|
A'chars'. Handle MRI character constants. Treat '"' as the
|
||||||
|
unary bitwise not operator. Treat $ as the program counter, or as
|
||||||
|
the prefix for a hex constant. Treat % as the prefix for a binary
|
||||||
|
constant and @ as the prefix for an octal constant. Treat : as
|
||||||
|
the prefix for a hex constant.
|
||||||
|
(op_encoding): Set '"' to O_bit_not, '<' to O_lt, and '>' to O_gt.
|
||||||
|
(op_rank): No longer const. Change rank values.
|
||||||
|
(expr_begin): New function.
|
||||||
|
(operator): New static function.
|
||||||
|
(expr): Use operator. Don't bother to mention the operator in
|
||||||
|
warnings. Remove bogus #if 0 code. Handle new operatorT values.
|
||||||

|
||||||
|
