middle-end/117137 - expansion issue with vector equality compares
When expanding a COND_EXPR with a vector equality compare as condition
expand_cond_expr_using_cmove fails to properly go the cbranch path.
I failed to massage it's twisted logic so the simple fix is to make
sure to expand a vector condition separately which also generates
the expected code for the testcase:
ptest %xmm0, %xmm0
cmovne %edi, %eax
PR middle-end/117137
* expr.cc (expand_cond_expr_using_cmove): Make sure to
expand vector comparisons separately.
* gcc.dg/torture/pr117137.c: New testcase.
