From: Fernando Endo Date: Sat, 15 Oct 2016 19:58:45 +0000 (-0500) Subject: cpu, arm: Distinguish Float* and SimdFloat*, create FloatMem* opClass X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6c72c3551978ef2eabbe9727bf24fd2fcf385318;p=gem5.git cpu, arm: Distinguish Float* and SimdFloat*, create FloatMem* opClass Modify the opClass assigned to AArch64 FP instructions from SimdFloat* to Float*. Also create the FloatMemRead and FloatMemWrite opClasses, which distinguishes writes to the INT and FP register banks. Change the latency of (Simd)FloatMultAcc to 5, based on the Cortex-A72, where the "latency" of FMADD is 3 if the next instruction is a FMADD and has only the augend to destination dependency, otherwise it's 7 cycles.
