Subject: [PATCH 4/5] ARM: use unified assembler in c files
Date: Thu, 7 Feb 2019 10:48:28 +0100 [thread overview]
Message-ID: <fed4850fb5d8a8ca874affa05d8d116d53e25b88.1549532513.git.stefan@agner.ch> (raw)
In-Reply-To: <cover.1549532513.git.stefan@agner.ch>
Use unified assembler syntax (UAL) in inline assembler. Divided
syntax is considered depricated. This will also allow to build
the kernel using LLVM's integrated assembler.
