Douglas Gregor	99734e7669	Lazily load the controlling macros for all of the headers known in the ... PCH file. In the Cocoa-prefixed "Hello, World" benchmark, this takes us from reading 503 identifiers down to 37 and from 470 macros down to 4. It also results in an 8% performance improvement. llvm-svn: 70094	2009-04-25 23:30:02 +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
