test.ll
Starting from
<a href="https://github.com/llvm/llvm-project/commit/e4f66a10556c82e2ebf2469fafc1c26639f15be8">https://github.com/llvm/llvm-project/commit/e4f66a10556c82e2ebf2469fafc1c26639f15be8</a>,
we have seen SEGV in one of our internal test.
I extracted a testcase test.ll to reproduce the same failure:
opt -passes=pgo-icall-prom -profile-summary-hot-count=10 -S test.ll -o
/dev/null
PLEASE submit a bug report to <a href="http://go/llvm-crash-bug">http://go/llvm-crash-bug</a> and include the crash
backtrace.
Stack dump:
0. Program arguments: opt -passes=pgo-icall-prom
-profile-summary-hot-count=10 -S test.ll -o /dev/null
Stack dump without symbol names (ensure you have llvm-symbolizer in your PATH
or set the environment var `LLVM_SYMBOLIZER_PATH` to point to it):
