Chris Lattner	47448288ee	MemoryBuffer::getFile got smarter, obviating the need for readfilefast. ... The new MemoryBuffer doesn't "leak" file descriptors and handles the small file case efficiently. llvm-svn: 49032	2008-04-01 06:06:37 +00:00
Steve Naroff	93eea6e1a0	Hack ReadFileFast() to raise the threshold of memory mapped files (from 4->12 pages). ... This is a temporary solution to avoid running out of file descriptors (which defaults to 256). Need to benchmark to understand the speed benefit. If the benefit is small, the simple solution is to avoid memory mapping files. If the benefit is significant, more thought is necessary. llvm-svn: 48991	2008-03-31 18:44:59 +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
