UPAGES layout.. it was entirely too comfortable with reading and writing the U area before. I've changed it to use PT_GETREGS/PT_PUTREGS ptrace ops instead of READ_U etc. The code to read the registers from core dumps is a bandaid at best. It seems to have problems reading core dumps from dynamic linked executables still, but at least static dumps work. I desperately need help from a gdb/bfd expert. :-) HELP!!
