Chad committed the patch last night, and the new lit test in the patch
broke one of the builders:
I've been trying to figure out why, but I'm at a loss because I can't
reproduce the failure under Ubuntu or Darwin using make check-all or
llvm-lit. I'm using a Release+Asserts build.
Initially I thought it might be a problem with the test case, but I find
it less likely now. My test case is patterned off of another that you
wrote for the ARM backend
(llvm/test/CodeGen/ARM/misched-copy-arm.ll). It uses a lot of
redirection to get the misched debug output piped to FileCheck. I've
gone over that and ran it in a terminal on Ubuntu and Darwin, but no
The builder output from FileCheck seems to indicate that llc might have
crashed. If this is the case, then it's easy to conclude that this is
the only test that failed because it's the only one that uses the
Machine Model for Cortex-A53. I just need to figure out how to get it to
fail. I've been digging through the artifacts tarball, but it only
includes clang and I can't sort out the correct options to emulate an
llc lit run.
Do you or anyone else have any ideas on how I might proceed?
