The attached patch is to fix ICEs for new pr65345-[45].c tests
on sh4-unknown-linux-gnu. It's a mechanical change referring
to the original i386 patch, though I'm not sure the change
for TARGET_EXPR is really needed for SH targets. I'd like to
apply it anyway, because it fixes the ICEs and there are no
new failures on sh4-unknown-linux-gnu. Committed.
