Track location via call_info rather than + munging context for every expansion. + Memory impact: none. + Speed impact: slight penalty, due to more bookkeeping. + * m4/m4module.h (m4_push_string_init): Add parameters. + * m4/m4private.h (struct m4_macro_args): Remove argv0 and + argv0_len, now redundant with info. + (m4__push_wrapup_init): Add parameter. + * m4/input.c (m4_push_string_init, m4__push_wrapup_init): Track + location from caller, rather than context. + (composite_peek, composite_read, match_input): Adjust callers. + * m4/utility.c (m4_symbol_value_lookup): Quote macro name. + (m4_verror_at_line): Allow NUL in macro name. + * m4/macro.c (trace_flush, m4_trace_prepare, trace_pre): Allow NUL + in trace. + (expand_macro): No longer munge context location. + (collect_arguments, m4_arg_text, m4_arg_empty, m4_arg_len) + (m4_make_argv_ref, m4_push_arg, m4_wrap_args): Adjust callers. + * modules/gnu.c (builtin, indir): Likewise. + * tests/null.m4: Enhance test. + * tests/null.err: Adjust expected output. + * tests/null.out: Likewise. + Stage 24b: Allow embedded NUL in macro names. Use length rather than NUL-termination when tracking macro names. All APIs dealing with symbol table changed. |
