Subject: [PATCH] gcov: remove support for GCC < 4.9
Date: Tue, 10 Nov 2020 19:05:56 -0800 [thread overview]
Message-ID: <20201111030557.2015680-1-ndesaulniers@google.com> (raw)
Since
commit 0bddd227f3dc ("Documentation: update for gcc 4.9 requirement")
the minimum supported version of GCC is gcc-4.9. It's now safe to remove
this code.
Similar to
commit 10415533a906 ("gcov: Remove old GCC 3.4 support")
but that was for GCC 4.8 and this is for GCC 4.9.
