Bug ID: 16041
Summary: soft-fp extensions should quiet signaling NaNs
Product: glibc
Version: 2.18
Status: NEW
Severity: normal
Priority: P2
Component: soft-fp
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: joseph at codesourcery dot com
soft-fp FP_EXTEND checks for signaling NaNs and raises the "invalid" exception
for them, but should also convert them to quiet NaNs; instead it leaves them as
signaling (and because the results are raw, the subsequent packing doesn't
alter this). (This doesn't get detected for powerpc-nofpu by math/basic-test.c
because such conversion tests are generally disabled for powerpc because of
issues with conversions between double and IBM long double.)
