[PATCH for-10.0 04/25] tests/fp: Explicitly set inf-zero-nan rule |
Date: |
Thu, 28 Nov 2024 10:42:49 +0000 |
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.
