Chris Lattner	ad13cf4e7a	eagerly resolve the spelling locations of macro argument preexpansions. ... This reduces fsyntax-only time on c99-intconst-1.c from 2.43s down to 2.01s (20%), reducing the number of fileid lookups from 2529040 linear and 64771121 binary to 5625902 linear and 4151182 binary. This knocks getFileID down to only 4.6% of compile time on this testcase. At this point, malloc/free is over 35% of compile time, primarily allocating MacroArgs objects and their argument preexpansion vectors. I don't feel like malloc avoiding right now, so I'm just going to call this good. llvm-svn: 62994	2009-01-26 04:33:10 +00:00
Chris Lattner	933d5ffc11	Optimize stringification a bit to avoid std::string thrashing and ... avoid the version of Preprocessor::getSpelling that returns an std::string. llvm-svn: 61769	2009-01-05 23:04:18 +00:00
Chris Lattner	7a51313d8a	Make a major restructuring of the clang tree: introduce a top-level ... lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. llvm-svn: 48402	2008-03-15 23:59:48 +00:00
