1not implemented: 2 - mode.input_allow_dollars. 3 - column counts do not take tabstops into account. 4 - mode.output_linenumbers. 5 - mode.do_depend. 6 - mode.do_macrolist. 7 - mode.do_trace. 8 - warns.endiflabels. (they cause errors) 9 - warns.unused. 10 - the -iremap option. 11 - $CPP_RESTRICTED 12 - other environment variables 13 14tidy up: 15 - get rid of inlinedefs.h 16 - use of places in and below macro.c is pretty bogus. 17 - macro code should be reworked. 18 - place_changefile is manky and wastes memory. Also, in an ideal 19 world we'd remember the place #line changed the name and refer 20 to it when printing errors. 21 22fix: 23 - "#if 0 && 1/0" should not crash; fix eval method. 24 - quote characters and comment delimiters that are emitted by 25 macros are not recognized. See: 26 t34 (should produce a quote and FOO Q) 27 t35 (similarly, this test may be redundant once it's fixed) 28 t36 (C(3) should produce nothing) 29 t37 (BC foo EC should produce nothing) 30 Joerg says comments like in t36 should be stripped exactly 31 twice, once when the macro is defined and again when it's 32 expanded. Note that gcc's cpp -traditional is getting t37 33 wrong, and it gets t36 wrong with -C. 34 - remove the intentionally undocumented -p option and generate 35 proper linenumber output. (also, in this code what happens if 36 a comment spans files? I bet currently it will emit the line 37 number into the comment.) 38
