Fri Dec 15 23:27:56 2000 Andrew Cagney <cagney@b1.cygnus.com>
* remote.c (remote_fetch_registers): Replace #ifdef
REGISTER_BYTES_OK with REGISTER_BYTES_OK_P.
* gdbarch.sh (REGISTER_BYTES_OK): Multi-arch.
* gdbarch.h, gdbarch.c: Re-generate.
Fri Dec 15 22:58:59 2000 Andrew Cagney <cagney@b1.cygnus.com>
* serial.c (serial_printf): Call xvasprintf instead of vasprintf.
