* configure.in: Add nlm subdir to configdirs for alpha-*-netware
target. * defs.h (enum language): Add language_asm. * findvar.c (read_register_bytes read_register_gen write_register_bytes read_register read_register_pid write_register write_register_pid supply_register): Move multi- thread handling down into these routines. Create XXX_pid routines that allow register references to specify the pid. * findvar.c infcmd.c (read_pc read_pc_pid write_pc write_pc_pid read_sp write_sp read_fp write_fp): Move these routines from infcmd to findvar to centralize the whole mess. * i386-nlmstub.c: Portability fixes. * infptrace.c (child_resume): Conditionalize to allow other natives to override it. Remove PIDGET gubbish, it's no longer necessary. * infrun.c (wait_for_inferior): Put registers_changed() before target_wait() to speed up remote debugging. * Replace code that reads registers from other threads with much nicer looking new function calls (see changes to findvar.c). * Don't skip prologues if debugging assembly source. * lynx-nat.c (child_resume): Lynx now needs it's own version of child_resume to handle multi-thread debugging properly. * remote.c: Add O response to get console output from target. * (readchar): Add timeout parameter. Handle SERIAL_EOF and SERIAL_ERROR here to simplify callers. * Change static var timeout to remote_timeout. * (fromhex): Remove unnecessary return -1 at end of routine. * (remote_wait): Turn this into a big switch statement. Add support for O response. * (putpkt): Remove unnecessary handling of SERIAL_EOF/ERROR. * (getpkt): Split getpkt into two parts. read_frame deals with all formatting issues, run-length encoding, and framing. getpkt now handles error recovery, and frame detection. * ser-tcp.c (tcp_readchar): Handle EINTR from read(). * ser-unix.c (hardwire_raw): Set CLOCAL so that we ignore modem control. (hardwire_readchar): Handle EINTR from read(). * symfile.c (deduce_language_from_filename): Add support for .s files. * config/nm-lynx.h: Define CHILD_WAIT so that lynx-nat.c can override infptrace's child_wait. * config/rs6000/rs6000lynx.mh: Use xm-rs6000ly.h & nm-rs6000ly.h instead of XXXlynx.h. * config/rs6000/rs6000lynx.mt: Use tm-rs6000ly.h instead of tm-rs6000lynx.h. * nlm/gdbserve.c: Portability fixes.
