Vedant Kumar 498432e86b [llvm-profdata] Speed up merging by using a thread pool ... 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 Differential Revision: https://reviews.llvm.org/D22438 llvm-svn: 275921		2016-07-18 22:02:39 +00:00
