From 27aedf7d25e148089bb54eb80588bd380483cbe5 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Wed, 11 Dec 2024 15:30:53 +0000 Subject: [PATCH] tests/fp: Explicitly set inf-zero-nan rule Explicitly set a rule in the softfloat tests for the inf-zero-nan muladd special case. In meson.build we put -DTARGET_ARM in fpcflags, and so we should select here the Arm rule of float_infzeronan_dnan_if_qnan.
