2012-08-29Keep history of macro definitions and #undefsAlexander Kornienko
Summary: Summary: Keep history of macro definitions and #undefs with corresponding source locations, so that we can later find out all macros active in a specified source location. We don't save the history in PCH (no need currently). Memory overhead is about sizeof(void*)*3*<number of macro definitions and #undefs>+<in-memory size of all #undef'd macros> I've run a test on a file composed of 109 .h files from boost 1.49 on x86-64 linux. Stats before this patch: *** Preprocessor Stats: 73222 directives found: 19171 #define. 4345 #undef. #include/#include_next/#import: 5233 source files entered. 27 max include stack depth 19210 #if/#ifndef/#ifdef. 2384 #else/#elif. 6891 #endif. 408 #pragma. 14466 #if/#ifndef#ifdef regions skipped 80023/451669/1270 obj/fn/builtin macros expanded, 85724 on the fast path. 127145 token paste (##) operations performed, 11008 on the fast path.

Preprocessor Memory: 7541687B total BumpPtr: 6066176 Macro Expanded Tokens: 417768 Predefines Buffer: 8135 Macros: 1048576 #pragma push_macro Info: 0 Poison Reasons: 1024 Comment Handlers: 8 In my test increase in memory usage is about 1.7Mb, which is ~28% of initial preprocessor's memory usage and about 0.8% of clang's total VMM allocation. As for CPU overhead, it should only be noticeable when iterating over all macros, and should mostly consist of couple extra dereferences and one comparison per macro + skipping of #undef'd macros. It's less trivial to measure, though, as the preprocessor consumes a very small fraction of compilation time.

2012-08-28Warn about suspicious implicit conversions from floating point to boolHans Wennborg
This warns in two specific situations: 1) For potentially swapped function arguments, e.g. void foo(bool, float); foo(1.7, false); 2) Misplaced brackets around function call arguments, e.g. bool InRange = fabs(a - b < delta); Where the last argument in a function call is implicitly converted from bool to float, and the function returns a float which gets implicitly converted to bool.
