I regularly use the -Meh_frame flag to include CFI information on binaries compiled with the PGI toolchain. This option works fine on x86 hosts, but appears to be absent from the PowerPC toolchain. It is documented in the user guide along with the caveat that “The eh_frame option is available only on newer Linux systems that supply the system unwind libraries”, but given I’m testing on RedHat 7.5 and newer, I expect this flag should be available.
Am I correct in this assumption? Is there anything I can do to enable -Meh_frame support?
