tccpp: allow "#define X defined Y ..." That means: we do not macro-expand the argument of 'defined' Also: store the last token position into the TokenString structure in order to get rid of the tok_last function. 2017-06-05 19:21:39 +08:00			`/* accept 'defined' as result of substitution */`

tccpp: macro cleanup - remove TOK_NOSUBST, mark the token itself instead - get_tok_str(); mask out SYM_FIELD & update uses - next(): optimize (~5% faster with tcc -E) - tok_flags: remove some redundancy - parse_define(): do not remove spaces around '##' and after '#' and mark macros with '##' as MACRO_JOIN to avoid unnecessary call to macro_twosharps(mstr): - next_nomacro(): removed, next_nomacro1(): renamed to next_nomacro() - next_argstream(): cleanup & new function peek_file() - macro_subst_tok(): handle special macros (__DATE__ etc.) like normal macros if they are #defined - -DPP_DEBUG : more structured output - pp_error(): better preprocessor expression error message - tcctok.h: sort basic keywords (somehow) - testspp/Makefile: generate .expect with 'make testspp.##+' - tcc.c: tcc -E -o file : put unixy LFs also on windows 2024-02-09 23:07:43 +08:00
