Subject: [PATCH v3 5/7] Partially revert "ARM: 8905/1: Emit __gnu_mcount_nc when using Clang 10.0.0 or newer"
Date: Wed, 2 Sep 2020 15:59:09 -0700 [thread overview]
Message-ID: <20200902225911.209899-6-ndesaulniers@google.com> (raw)
In-Reply-To: <20200902225911.209899-1-ndesaulniers@google.com>
This partially reverts commit b0fe66cf095016e0b238374c10ae366e1f087d11.
The minimum supported version of clang is now clang 10.0.1. We still
want to pass -meabi=gnu.
