Currently, getSourceFile accesses file system to check if two paths are the same file with a thread lock, which is a huge performance bottleneck in some cases. Currently, it's accessing file system size(files) * size(files) times. Thus, cache file status information, which reduces file system access to size(files) times. When I tested it with two binaries and 16 cpu cores, it saved over 70% of time. Binary 1: 56 secs -> 3 secs Binary 2: 17 hours -> 4 hours Differential Revision: https://reviews.llvm.org/D97061 |
