Subject: [PATCH v2 03/14] LoongArch: Fix SI division for loongarch32 target
Date: Wed, 9 Aug 2023 19:46:10 +0800 [thread overview]
Message-ID: <20230809115325.3716347-4-c@jia.je> (raw)
In-Reply-To: <20230809115325.3716347-1-c@jia.je>
Add TARGET_64BIT check for loongarch64-only handling of SI division. It
shall not promote SI to DI before division in loongarch32 target.
gcc/ChangeLog:
* config/loongarch/loongarch.md: Add TARGET_64BIT check for
loongarch64-only handling of SI division.
