6.2.0 based devel/powerpc64-gcc rejects sys/powerpc/powerpc/db_trace.c for very old code

[Mark Millard]

I have submitted:

Bug 215600 - devel/powerpc64-gcc based buildkernel: sys/powerpc/powerpc/db_trace.c rejected for: '__builtin_frame_address' with a nonzero argument is unsafe

sys/powerpc/powerpc/db_trace.c -r132070 2004-Jul-12 is when this
__builtin_frame_address use was introduced:

void
db_trace_self(void)
{
        db_addr_t addr;

        addr = (db_addr_t)__builtin_frame_address(1);
        db_backtrace(curthread, addr, -1);
}



head was at -r310556 for this discovery but with a patch for libdwarf
in ctfconvert to enable buildkernel to get this far. I have not yet
updated to the 6.3.0 based devel/powerpc64-gcc .
