Subject: [PATCH v5 06/14] riscv: extend concatenated alternatives-lines to the same length
Date: Fri, 21 Jan 2022 17:36:10 +0100 [thread overview]
Message-ID: <20220121163618.351934-7-heiko@sntech.de> (raw)
In-Reply-To: <20220121163618.351934-1-heiko@sntech.de>
ALT_NEW_CONTENT already uses same-length assembler lines, so
extend this to the other elements as well.
This makes it more readable when these elements need to be extended
in the future.
