Bug ID: 61193 Summary: ABI incompatibility between POWER and Z HTM builtins and intrinsics Product: gcc Version: 4.8.3 Status: UNCONFIRMED Severity: blocker Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: bergner at gcc dot gnu.org An ABI incompatibility between POWER and Z HTM builtins and intrinsics has been found. The incompatibility is on mainline, 4.9 and 4.8. We're still waiting to hear what the XL team has implemented for their return status. Does the XL on POWER and Z match the POWER or Z sematics? Does XL on POWER match GCC on POWER and XL on Z match GCC on Z? We're tracking that answer down now. The intent was that common code on all platforms and compilers would have the same ABI.
