Bug ID: 86160
Summary: Implement isinf on PowerPC
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: meissner at gcc dot gnu.org
Target Milestone: ---
PowerPC with the VSX instruction set has the xststdcdp instruction that can be
used to test if a value is infinity (and the xststdcqp instruction for IEEE
128-bit). We should use this for the IEEE math builtins like __builtin_isinf.
