Add a "-j" option to llvm-profdata to control the number of threads used. Auto-detect NumThreads when it isn't specified, and avoid spawning threads when they wouldn't be beneficial. I tested this patch using a raw profile produced by clang (147MB). Here is the time taken to merge 4 copies together on my laptop: No thread pool: 112.87s user 5.92s system 97% cpu 2:01.08 total With 2 threads: 134.99s user 26.54s system 164% cpu 1:33.31 total Changes since the initial commit: - When handling odd-length inputs, call ThreadPool::wait() before merging the last profile. Should fix a race/off-by-one (see r275937). Differential Revision: https://reviews.llvm.org/D22438 llvm-svn: 275938 |
