Changes to account for name change from cygwin32 to cygwin and clean up Win32-related ifdefs. * configure.tgt: check for cygwin* instead of cygwin32. New cygwin gdb_target variable loses the "32". * configure.host: check for cygwin* instead of cygwin32.

1995-08-02Update FSF address.Fred Fish1-1/+1
1995-06-08typo in tcp_openStu Grossman1-0/+1
1995-06-08 * defs.h maint.c monitor.c remote-mips.c remote.c: Add supportStu Grossman1-17/+27
for `watchdog' variable. This allows the user to put an upper limit on the amount of time that GDB will wait for the target to return from a step or continue operation. This will primarily be used for the testsuite, where it is difficult to come up with a reasonable timeout for things like function calls, which can take as long as three minutes under some circumstances. If the watchdog timer expires, GDB will generate an error that looks like `Watchdog has expired.', and will detach from the target. * remote-mips.c (mips_open): Setup initial frame from target. Print it out so that user is told where the program is stopped when they attach. * remote-nrom.c: Loads of cleanups. Use serial code to open network connections. Use expect() to wait for response to download command. * ser-tcp.c (tcp_open): Retry connection if we get ECONNREFUSED. * serial.c serial.h (serial_open serial_fdopen serial_close): Allow users to open the same device multiple times. They all get to share the same serial_t. This is about the only way to have multiple active targets use the same device (for download and debug). * sparcl-tdep.c: Keep #include <unistd.h> away from GO32. * target.c: Add `targetdebug' variable. If this is non-zero, then a special target is put at the top of the target stack which will cause all calls through the target vector to have their args and results printed out.
1995-03-07 * serial.h ser-go32.c ser-go32-para.c ser-mac.c ser-tcp.cStu Grossman1-0/+10
ser-unix.c: Add SERIAL_SETSTOPBITS to set the number of stopbits (needed for IDP board?!?!?).
1994-12-23 * ser-tcp.c (tcp_open): Cast to struct sockaddr when passing toJim Kingdon1-1/+1
function which expects that.
1994-06-02 * configure.in: Add nlm subdir to configdirs for alpha-*-netwareStu Grossman1-1/+6
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.
1993-11-01Change the stream argument to _filtered to GDB_FILE *.Thomas Lord1-1/+1
Change all references to stdout/stderr to gdb_stdout/gdb_stderr. Replace all calls to stdio output functions with calls to corresponding _unfiltered functions (`fprintf_unfiltered') Replaced calls to fopen for output to gdb_fopen. Added sufficient goo to utils.c and defs.h to make the above work. The net effect is that stdio output functions are only directly used in utils.c. Elsewhere, the _unfiltered and _filtered functions and GDB_FILE type are used. In the near future, GDB_FILE will stop being equivalant to FILE. The semantics of some commands has changed in a very subtle way: called in the right context, they may cause new occurences of prompt_for_continue() behavior. The testsuite doesn't notice anything like this, though. Please respect this change by not reintroducing stdio output dependencies in the main body of gdb code. All output from commands should go to a GDB_FILE. Target-specific code can still use stdio directly to communicate with targets.
1993-10-08 * inflow.c: Remove unused includes of sys/param.h, etc.Jim Kingdon1-10/+0
* inflow.c, ser-unix.c, ser-go32.c, ser-tcp.c, serial.h, terminal.h: Move all the process group stuff back to inflow.c; that's a better place for it and fixes problems with trying to get/set the process group of a tty we're doing remote debugging on. * terminal.h: Skip the redefine crap if HAVE_TERMIOS.
1993-09-08gcc lintK. Richard Pixley1-1/+1
1993-07-28 * serial.h, ser-{unix,go32,tcp}.c: Add flush_input and send_break.Jim Kingdon1-4/+4
* nindy-share/*, remote-nindy.c: Extensive hacking to make it conform to GDB conventions like using memcpy not bcopy, serial.h, etc. This is to make it host on Solaris, AIX, etc. * Makefile.in: Reflect removed nindy-share files.
1993-06-30 * inftarg.c: Remove unused include of terminal.h.Jim Kingdon1-0/+40
* signals.h: Don't undefine signals anymore. * main.c: Use job_control from serial.h. * fork-child.c (fork_inferior): Use gdb_setpgid. * serial.h, ser-unix.c, ser-go32.c: Provide gdb_setpgid. * utils.c (quit): Use current_target->to_terminal_ours to figure out whether we care about lack of job control, rather than __GO32__. * utils.c: Include serial.h not terminal.h (quit): Use job_control not TIOCGPGRP. * terminal.h: Don't undefine TIOCGPGRP. * serial.h, ser-unix.c, ser-go32.c, ser-tcp.c: Add SERIAL_FLUSH_OUTPUT. * utils.c (quit): Use it. * serial.h: Add SERIAL_UN_FDOPEN. * utils.c (quit): Use it. * ser-unix.c: Add process group to ttystate. [HAVE_SGTTY]: Add tchars, ltchars, and lmode to ttystate. * inflow.c: Include serial.h not terminal.h. Use serial.h stuff to replace most of the maze of #ifdef's. * inflow.c, main.c, inferior.h: make gdb_has_a_terminal a function. * serial.h: Document SERIAL_SET_TTY_STATE as being immediate. * ser-unix.c: Use TIOCSETN not TIOCSETP so it is true. * serial.h, ser-unix.c, ser-go32.c, ser-tcp.c: Add SERIAL_PRINT_TTY_STATE, SERIAL_NOFLUSH_SET_TTY_STATE, and SERIAL_SET_PROCESS_GROUP. * inflow.c: Use them. * config/xm-svr4.h, config/rs6000/xm-rs6000.h, config/sparc/sun4os4.h: Define HAVE_TERMIOS. * Various: Remove all use of TIOC*_BROKEN.
1993-06-26 * remote.c: Add arg names to prototypes, in a modest effort atStu Grossman1-16/+26
clarification. Also add prototypes for some new functions. * (remote_wait): Better error reporting for 'T' responses. * ser-go32.c (strncasecmp): Make str1 & str2 be const. * (dos_async_init): Make usage message reflect requested port #. * ser-tcp.c (tcp_open): Terminate hostname properly to prevent random hostname lookup failures.
