Hi,
In make_new_ssa_for_def (tree-reassoc.c) we should use gimple_get_lhs to
get lhs instead of gimple_assign_lhs as stmt can be builtins too.
Attached patch fixes this.
Testcase from PR (attached) seems to fail. I dont any fortran so I didnt
try fixing it. Any help here is appreciate. The log is:

Excess errors:
I didn't add it due to this. I will leave it to someone else.
Bootstrapped and regression tested the attached patch on
x86_64-linux-gnu with no new regressions.
Is this OK for trunk?
Thanks,
