        OS/Version: Linux
            Status: NEW
          Severity: normal

This test fails llc/jit/cbe. I ran bugpoint-cbe and it reduced this test case:

*** The following function is being miscompiled:  main_bb1139_2E_ce
<llc><gcc>You can reproduce the problem with the command line:
  llc -f bugpoint.test.bc -o bugpoint.test.bc.s
  gcc ./bugpoint.safe.bc.llc.s.so bugpoint.test.bc.s -o bugpoint.test.bc.exe -Wl,-R.
  bugpoint.test.bc.exe
The shared object was created with:
  llc -march=c bugpoint.safe.bc -o temporary.c
  gcc -xc temporary.c -O2 -o ./bugpoint.safe.bc.llc.s.so -shared
-fno-strict-aliasing

I'll attach the various files.
