log of running update_cc_test_checks.py
While working on updating tests for a patch for <a class="bz_bug_link
bz_status_NEW "
title="NEW - [PowerPC] vec_splats cannot be used to initialize variables with static storage duration"
href="show_bug.cgi?id=44276">bug #44276</a>, running
`llvm/utils/update_cc_test_checks.py` to update the
`clang/test/CodeGen/ppc-emmintrin.c` produced a test that failed.
Updating this test on master (without any patches) caused the same issue. The
the other `ppc-*mmintrin.c` tests passed, but significantly altered the test
checks.
See attached for a log of running:
$ PATH="$HOME/devel/llvm-builds/master-clang-assert/bin:$PATH" \
./llvm/utils/update_cc_test_checks.py -v \
--llvm-bin=$HOME/devel/llvm-builds/master-clang-assert/bin \
clang/test/CodeGen/ppc-xmmintrin.c
Also attached are:
a) a shorter log of the command without the `-v` flag, which has some
warnings that are kind of obscured in the verbose log. Updating other
`ppc-*mmintrin.c` tests displays similar warnings.
b) output of `ninja check-clang`
c) the updated `ppc-emmintrin.c`
d) a diff of the update to `ppc-emmintrin.c`
e) a diff of the updates to all of `ppc-*mmintrin.c`</pre>
