From aa41680e481456917824e3794c526521b9520589 Mon Sep 17 00:00:00 2001 From: Stafford Horne Date: Thu, 21 Oct 2021 22:11:27 +0900 Subject: [PATCH] or1k: Update FPU to specify detect tininess before rounding This was not defined in the spec and not consistent in the implementation causing incosistent behavior. After review we have updated the CPU implementations and proposed the spec be updated to specific that FPU tininess checks check for tininess before roudning.
