wlei a5f411b7f8 [llvm-profgen] Allow unsymbolized profile as perf input ... This change allows the unsymbolized profile as input. The unsymbolized profile is created by `llvm-profgen` with `--skip-symbolization` and it's after the sample aggregation but before symbolization , so it has much small file size. It can be used for sample merging and trimming, also is useful for debugging or adding test cases. A switch `--unsymbolized-profile=file-patch` is added for this. Format of unsymbolized profile: ``` [context stack1] # If it's a CS profile number of entries in RangeCounter from_1-to_1:count_1 from_2-to_2:count_2 ...... from_n-to_n:count_n number of entries in BranchCounter src_1->dst_1:count_1 src_2->dst_2:count_2 ...... src_n->dst_n:count_n [context stack2] ...... ``` Reviewed By: hoy, wenlei Differential Revision: https://reviews.llvm.org/D111750		2021-10-25 23:58:08 -07:00
