Subject: [PATCH v3] include/linux/compiler*.h: define asm_volatile_goto
Date: Wed, 31 Oct 2018 12:39:01 -0700 [thread overview]
Message-ID: <20181031193903.203914-1-ndesaulniers@google.com> (raw)
In-Reply-To: <CAHk-=wj-17w3-m9EGVZGeWYpuYM8V=x8py2s5EcAHeinF24TQg@mail.gmail.com>
asm_volatile_goto should also be defined for other compilers that support
asm goto.
Fixes commit 815f0ddb346c ("include/linux/compiler*.h: make compiler-*.h
mutually exclusive").
