Subject: [PATCH 01/17] Replace another snippet with a call to, gimple_range_ssa_names.
Date: Thu, 22 Sep 2022 14:53:24 -0400 [thread overview]
Message-ID: <b17227f0-cdcf-f25b-58fb-4ad2751ff772@redhat.com> (raw)
In-Reply-To: <571782f9-72e6-5c30-da55-b8d62d3a153e@redhat.com>
[-- Attachment #1: Type: text/plain, Size: 190 bytes --]
When the original patch was applied, I missed a spot which could
also be rewritten to use gimple_range_ssa_names.
Bootstrapped on x86_64-pc-linux-gnu with no regressions. Pushed.
