Subject: Re: [PATCH v3] RISC-V:Optimize the MASK opt generation
Date: Wed, 6 Sep 2023 11:42:27 +0800 [thread overview]
Message-ID: <CA+yXCZB7k5rJPErGKM7s=0Yad=JWFipo6S0spkqsGx8UzB=-Lw@mail.gmail.com> (raw)
In-Reply-To: <20230906020216.5995-1-wangfeng@eswincomputing.com>
Reading the manual again, it seems I missed something in the manual
before, the MASK syntax already says we can specify Var to select the
variable other than target_flags, but I tried that not work when we
only declare Mask with Var (e.g. "Mask(VECTOR_ELEN_32)
Var(riscv_vector_elen_flags)" still using target_flags)
So maybe we should just fix that instead of extending the syntax?
e.g.
Mask(VECTOR_ELEN_32) Var(riscv_vector_elen_flags)
rather than
Mask(VECTOR_ELEN_32) in TargetVariable(riscv_vector_elen_flags)
