Subject: [PATCH] Fix iteration over loads in SLP optimize
Date: Wed, 28 Oct 2020 14:45:35 +0100 (CET) [thread overview]
Message-ID: <nycvar.YFH.7.76.2010281445190.31087@elmra.sevgm.obk> (raw)
I've made a typo when refactoring the iteration over all loads in
the SLP graph. Fixed.
Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.

* tree-vect-slp.c (vect_optimize_slp): Fix iteration over
all loads.
