Subject: [PATCH 1/6] MIPSr6/math: Use builtin fma and fmaf
Date: Mon, 13 May 2024 16:14:24 +0800 [thread overview]
Message-ID: <20240513081429.1749898-2-syq@gcc.gnu.org> (raw)
In-Reply-To: <20240513081429.1749898-1-syq@gcc.gnu.org>
MIPSr6 has MADDF.s/MADDF.d instructions, which are fused.
In MIPS ISA, double support can be subsetted. Only FMAF is enabled
for this case.
