Subject: [PATCH v3 5/8] target/sparc: Use DYNAMIC_PC_LOOKUP for conditional branches
Date: Wed, 28 Jun 2023 09:11:59 +0200	[thread overview]
Message-ID: <20230628071202.230991-6-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230628071202.230991-1-richard.henderson@linaro.org>

When resolving JUMP_PC, we know this is for a plain branch
with no other side effects.
