Bug ID: 115800 Summary: PowerPC GCC cannot build a little endian compile if --with-cpu=power5 is used Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: meissner at gcc dot gnu.org Target Milestone: --- The libgfortran and libstdc++-v3 libraries cannot be built if you build a little endian compiler and set the default cpu to power5. The reason appears to be the libraries both assume that if a little endian target is being built, that IEEE 128-bit floating point is supported. But power5 does not support the VSX instruction set and registers, so IEEE 128-bit floating point is not available.
