Problem ScheduleDAG on PowerPC, X86 works fine.
Long story short: https://llvm.org/bugs/show_bug.cgi?id=31890
The backend fails to schedule a given DAG, the reason being that there is
an instruction and it glue that needs to be broken apart as they can't be
scheduled consecutively. See attached file for a picture of the DAG.
Not sure what's the best course of action is, and not sure why this isn't a
problem for the X86 backend

My experience using -DLLVM_BUILD_INSTRUMENTED_COVERAGE to generate coverage
...I'm not sure what's causing this... I
guess it has something to do with merging the profile data for multiple
binaries? The error message is not very helpful.
5. The HTML output highlights the semicolon after a break or return
statement in some switch statements in red. (For example,
LowerADDC_ADDE_SUBC_SUBE in ARMISelLowering.cpp.) Not really important,
but annoying.
6. On the bright side, when it works, the generated coverage information
is precise and easy to read.
