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 .
