Subject: [PATCH 06/10] powerpc: remove GCC version check for UPD_CONSTR
Date: Fri, 10 Sep 2021 16:40:43 -0700 [thread overview]
Message-ID: <20210910234047.1019925-7-ndesaulniers@google.com> (raw)
In-Reply-To: <20210910234047.1019925-1-ndesaulniers@google.com>
Now that GCC 5.1 is the minimum supported version, we can drop this
workaround for older versions of GCC. This adversely affected clang,
too.
