From e6a5f237bc02de146e2416cf3d8bec7473e33483 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Mon, 27 Jul 2020 18:27:50 +1000 Subject: [PATCH] FPU: Implement fmul[s] This implements the fmul and fmuls instructions. For fmul[s] with denormalized operands we normalize the inputs before doing the multiplication, to eliminate the need for doing count-leading-zeroes on P. This adds 3 or 5 cycles to the execution time when one or both operands are denormalized.
