``` /// Symbols can be appended with "(.__uniq.xxxx)?.llvm.yyyy" where "xxxx" and /// "yyyy" are numbers that could change between builds. We need to use the root /// symbol name before this suffix so these symbols can be matched with profiles /// which may have different suffixes. ``` Just like what we are doing in BP, https://github.com/llvm/llvm-project/blob/main/lld/MachO/BPSectionOrderer.cpp#L127 the patch removes the suffixes when parsing the order file and getting the symbol priority to have a better symbol match. --------- Co-authored-by: Sharon Xu <sharonxu@fb.com> Co-authored-by: Ellis Hoag <ellis.sparky.hoag@gmail.com>
