re PR middle-end/17767 (MMX intrinsics cause internal compiler error)
PR middle-end/17767
* cse.c (fold_rtx) [RTX_COMPARE, RTX_COMM_COMPARE]: Don't attempt
any simplifications of vector mode comparison operators.
* simplify-rtx.c (simplify_relational_operation): Fix variable name.
testsuite:
* gcc.dg/i386-mmx-6.c: New test case.
