Subject: [PATCH AUTOSEL 5.12 10/43] ARM: 9087/1: kprobes: test-thumb: fix for LLVM_IAS=1
Date: Sat, 10 Jul 2021 19:48:42 -0400 [thread overview]
Message-ID: <20210710234915.3220342-10-sashal@kernel.org> (raw)
In-Reply-To: <20210710234915.3220342-1-sashal@kernel.org>
From: Nick Desaulniers <ndesaulniers@google.com>
[ Upstream commit 8b95a7d90ce8160ac5cffd5bace6e2eba01a871e ]
There's a few instructions that GAS infers operands but Clang doesn't;
from what I can tell the Arm ARM doesn't say these are optional.
F5.1.257 TBB, TBH T1 Halfword variant
F5.1.238 STREXD T1 variant
F5.1.84 LDREXD T1 variant
