Subject: [PATCH AUTOSEL 6.1 11/20] x86/build: Move '-mindirect-branch-cs-prefix' out of GCC-only block
Date: Tue, 31 Jan 2023 09:59:37 -0500 [thread overview]
Message-ID: <20230131145946.1249850-11-sashal@kernel.org> (raw)
In-Reply-To: <20230131145946.1249850-1-sashal@kernel.org>
From: Nathan Chancellor <nathan@kernel.org>
[ Upstream commit 27b5de622ea3fe0ad5a31a0ebd9f7a0a276932d1 ]
LLVM 16 will have support for this flag so move it out of the GCC-only
block to allow LLVM builds to take advantage of it.
