Bug #: 15497
Summary: PowerPC: hypotf invalid return for -INF
Product: glibc
Version: 2.18
Status: NEW
Severity: normal
Priority: P2
Component: math
AssignedTo: unassigned@sourceware.org
ReportedBy: azanella@linux.vnet.ibm.com
Classification: Unclassified
The following libm testcases fails on POWER6 or order machine:
Failure: Test: hypot (-inf, qNaN) == inf
Result:
is: qNaN
should be: inf inf
Failure: Test: hypot (qNaN, -inf) == inf
Result:
is: qNaN
should be: inf inf
This is due sysdeps/powerpc/fpu/e_hypotf.c does not handle correctly -INF input
and handle as NAN.
