2008-03-31Hack ReadFileFast() to raise the threshold of memory mapped files (from ↵Steve Naroff
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48991 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Added variation of the "Report" method in the class Diagnostic that takesTed Kremenek
an optional DiagnosticClient argument that differs from the client stored internally in the Diagnostic object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48986 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
