Subject: [PATCH 4.14 70/94] arm64: jump_label.h: use asm_volatile_goto macro instead of "asm goto"
Date: Mon, 8 Oct 2018 20:31:51 +0200 [thread overview]
Message-ID: <20181008175609.878854378@linuxfoundation.org> (raw)
In-Reply-To: <20181008175605.067676667@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miguel Ojeda <miguel.ojeda.sandonis@gmail.com>
[ Upstream commit 13aceef06adfaf93d52e01e28a8bc8a0ad471d83 ]
All other uses of "asm goto" go through asm_volatile_goto, which avoids
a miscompile when using GCC < 4.8.2. Replace our open-coded "asm goto"
statements with the asm_volatile_goto macro to avoid issues with older
toolchains.
