Hi,

This patch checks optab exists before using it vector vector statement lowering.  It fixes compilation of test from PR68062 with -funsigned-char option added (doesn't fix original testcase).  Bootstrapped for x86_64-unknown-linux-gnu.  OK for trunk if no regressions?

Thanks,
Ilya

OK.

Just curious, what was the tree code for which we couldn't find asuitable optab?
