Subject: [PATCH v1] RISC-V: Refactor vxrm_mode attr for type attr equal
Date: Thu, 29 Jun 2023 14:00:54 +0800 [thread overview]
Message-ID: <20230629060054.617743-1-pan2.li@intel.com> (raw)
From: Pan Li <pan2.li@intel.com>
This patch would like to refactor the vxrm_mode attr for duplicated
eq_attr condition. The common condition of attr is extraced to one
place instead of many places.
Signed-off-by: Pan Li <pan2.li@intel.com>
gcc/ChangeLog:
* config/riscv/vector.md: Refactor the common condition.
