Bug ID: 83112 Summary: Silence warnings from PowerPC libgcc float128-ifunc.c compilation Product: gcc Version: 8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgcc Assignee: unassigned at gcc dot gnu.org Reporter: meissner at gcc dot gnu.org Target Milestone: --- The ifunc handlers in libgcc to switch between using PowerPC ISA 2.07 software emulation for IEEE 128-bit floating point and ISA 3.0 hardware instructions get a lot of warnings due to the new option -Wattribute-alias. The solution is to change the ifunc handler from returning void * to a pointer to the appropriate function.
