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.
