bugpoint output
Bugpoint crashes when debugging a llc-miscompilation. The crash appeared in
LLVM r99160.
Crash is verified to happen only on CellBE-linux (Linux
2.6.25-2-powerpc64-smp), when targeting the SPU. (This might not be platform
specific: SPU backend just seems to have a lot of miscompilations.)
LLVM is compiled with 'gcc (Ubuntu 4.3.2-1ubuntu12) 4.3.2'
bugpoint command line used:
'bugpoint bug.ll -run-llc --tool-args --march=cellspu'
Full output and failing testcase as attachment. The slightly non-default gcc
used by bugpoint is a link to /usr/bin/spu-gcc.
