tccpp: fix issues, add tests * fix some macro expansion issues * add some pp tests in tests/pp * improved tcc -E output for better diff'ability * remove -dD feature (quirky code, exotic feature, didn't work well) Based partially on ideas / researches from PipCet Some issues remain with VA_ARGS macros (if used in a rather tricky way). Also, to keep it simple, the pp doesn't automtically add any extra spaces to separate tokens which otherwise would form wrong tokens if re-read from tcc -E output (such as '+' '=') GCC does that, other compilers don't. * cleanups - #line 01 "file" / # 01 "file" processing - #pragma comment(lib,"foo") - tcc -E: forward some pragmas to output (pack, comment(lib)) - fix macro parameter list parsing mess from a3fc54345949535524d01319e1ca6378b7c2c201 a715d7143d9d17da17e67fec6af1c01409a71a31 (some coffee might help, next time ;) - introduce TOK_PPSTR - to have character constants as written in the file (similar to TOK_PPNUM) - allow '\' appear in macros - new functions begin/end_macro to: - fix switching macro levels during expansion - allow unget_tok to unget more than one tok - slight speedup by using bitflags in isidnum_table Also: - x86_64.c : fix decl after statements - i386-gen,c : fix a vstack leak with VLA on windows - configure/Makefile : build on windows (MSYS) was broken - tcc_warning: fflush stderr to keep output order (win32)

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
