From 4ec799dd17dcbb0fa4e90e685d5d6fcf8f72338a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Cl=C3=A9ment=20Chigot?= Date: Fri, 25 Apr 2025 11:35:13 +0200 Subject: [PATCH] target/sparc: don't set FSR_NVA when comparing unordered floats MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit FSR_NVA should be set when one of the operands is a signaling NaN or when using FCMPEx instructions. But those cases are already handled within check_ieee_exception or floatxx_compare functions. Otherwise, it should be left untouched. FTR, this was detected by inf-compare-[5678] tests within gcc testsuites.
