Test 176.gcc from SPEC CPU2000 fails at execution time on powerpc-linux when
compiled with "-O2 -ftree-vectorize -maltivec". The stack frame is corrupted
but the last few entries are several recursive calls of reload which calls
spill_failure which calls asm_noperands. This is odd, but when _either_
reload.c or reload1.c is compiled without -ftree-vectorize, the test runs to
completion and the output is as expected.
I don't have a minimized testcase. The failure starts with:
