The error message I posted earlier was when using O1
<https://reviews.llvm.org/owners/package/1/> + new PM, but it crashes with the
old one & no optimizations:
$ cat /tmp/repro.cc
void a() {
for (; int b = 0;) continue;
}
$ clang -c /tmp/repro.cc -o /tmp/repro.o
Referring to a basic block in another function!
br label %for.inc
in function _Z1av
fatal error: error in backend: Broken function found, compilation aborted!
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
Stack dump:
0. Program arguments: clang -c /tmp/repro.cc -o /tmp/repro.o
1. <eof> parser at end of file
2. Per-function optimization
3. Running pass 'Module Verifier' on function '@_Z1av'
