Subject: [PATCH 5.4 16/16] crypto: arm/ghash-ce - define fpu before fpu registers are referenced
Date: Thu, 30 Jun 2022 15:47:10 +0200 [thread overview]
Message-ID: <20220630133231.416143558@linuxfoundation.org> (raw)
In-Reply-To: <20220630133230.936488203@linuxfoundation.org>
From: Stefan Agner <stefan@agner.ch>
commit 7548bf8c17d84607c106bd45d81834afd95a2edb upstream
Building ARMv7 with Clang's integrated assembler leads to errors such
as:
arch/arm/crypto/ghash-ce-core.S:34:11: error: register name expected
t3l .req d16
^
Since no FPU has selected yet Clang considers d16 not a valid register.
Moving the FPU directive on-top allows Clang to parse the registers and
allows to successfully build this file with Clang's integrated assembler.
