A bugpoint reduced test case.
I am seeing an assertion in llvm::DIEEntry::EmitValue from the past few days.
The assertion is seen with "-O2 -g". Clearly the issue is related to debugging
info. I have attached a bug point reduced test case.
My command line goes like
clang -target arm-none-linux-gnueabi -mfloat-abi=softfp -mfpu=neon
-mcpu=cortex-a9 -O2 -g -c /tmp/test.c
I used git bisect to triage the issue and figured out the following commit
caused it.
0d9056d7660a6fecfdd704395e7f629e4f65c11c is the first bad commit
commit 0d9056d7660a6fecfdd704395e7f629e4f65c11c
