From 703990100a34e289716e0a5b4c2bb12a14b32597 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Wed, 11 Dec 2024 15:30:58 +0000 Subject: [PATCH] target/i386: Set Float3NaNPropRule explicitly Set the Float3NaNPropRule explicitly for i386. We had no i386-specific behaviour in the old ifdef ladder, so we were using the default "prefer a then b then c" fallback; this is actually the correct per-the-spec handling for i386.
