From 8d988eb44cd2723a6bd31a2895bdaba48524b6e0 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 5 Nov 2024 10:09:55 +0000 Subject: target/xtensa: Explicitly set 2-NaN propagation rule MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Set the NaN propagation rule explicitly in xtensa_use_first_nan(). (When we convert the softfloat pickNaNMulAdd routine to also select a NaN propagation rule at runtime, we will be able to remove the use_first_nan flag because the propagation rules will handle everything.)
