Subject: [PATCH] Add missing check for gassign.
Date: Thu, 18 Jun 2020 09:42:31 +0200 [thread overview]
Message-ID: <333748b3-0caf-e888-812d-bdd8d2120a15@suse.cz> (raw)
Hi.
We should check for gassign before doing gimple_assign_rhs_code and friends.
Ready to be installed after proper testing?
Thanks,
Martin
gcc/ChangeLog:
* tree-vect-generic.c (expand_vector_condition): Check
for gassign before inspecting RHS.
