| | | | | | | | | start of a filename, not a filename+length. All clients can produce a null terminated name, and the system api's require null terminated strings anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49041 91177308-0d34-0410-b5e6-96231b3b80d8
* Reimplement MemoryBuffer::getFile with three enhancements:Chris Lattner2008-04-011-85/+64
| | | | | | | | | | | | | | | | | | | | | | | 1) stop using MappedFile. 2) if profitable use the sys::path::MapInFilePages api to read the file. 3) otherwise fallback to read. When sys::path::MapInFilePages is implemented, this provides several benefits: #1: this avoids fragmenting memory for small files. #2: this avoids extraneous stat calls when the file size is known. #3: this only keeps the file descriptor open while reading the file, not for the duration of the lifetime of the memory buffer. This fixes a serious clang FD 'leak' problem. I believe that this will work on a win32 machine, but I don't have one to test on. I'd appreciate it if someone could check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49031 91177308-0d34-0410-b5e6-96231b3b80d8

* Change DiffFilesWithTolerance to be written in terms of MemoryBuffer,Chris Lattner2008-04-011-73/+56
