[PATCH 09/17] target/hexagon: Use float32_muladd for helper_sffms


From: Richard Henderson
Subject: [PATCH 09/17] target/hexagon: Use float32_muladd for helper_sffms
Date: Sun, 8 Dec 2024 16:48:36 -0600

There are no special cases for this instruction.  Since hexagon
always uses default-nan mode, explicitly negating the first
input is unnecessary.  Use float_muladd_negate_product instead.
