Bug ID: 59833
Summary: ARM soft-float extendsfdf2 fails to quiet signaling
NaN
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: jsm28 at gcc dot gnu.org
Target: arm*-*-*
The ARM soft-float aeabi_f2d / extendsfdf2 converts a signaling NaN to another
signaling NaN, when it should quiet it. This causes the glibc math/basic-test
to fail:
Failure: double x = (double) (float) sNaN, !issignaling
