Subject: [PATCH] ARM: unwind: remove old check for GCC <= 4.2
Date: Tue, 10 Nov 2020 18:51:20 -0800 [thread overview]
Message-ID: <20201111025120.1694158-1-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.
