It is +possible to catch signals that happened in the debuggee, deliver +signals to it, interrupt it with Ctrl-C, etc. (Previously, a signal +would kill the program being debugged.) Programs that hook hardware +interrupts (keyboard, timer, etc.) can also be debugged. + +It is now possible to debug DJGPP programs that redirect their +standard handles or switch them to raw (as opposed to cooked) mode, or +even close them. The command ``run < foo > bar'' works as expected, +and ``info terminal'' reports useful information about the debuggee's +terminal, including raw/cooked mode, redirection, etc. + +The DJGPP version now uses termios functions for console I/O, which +enables debugging graphics programs. Interrupting GDB with Ctrl-C +also works. + +DOS-style file names with drive letters are now fully supported by +GDB. + +It is now possible to debug DJGPP programs that switch their working +directory. It is also possible to rerun the debuggee any number of +times without restarting GDB; thus, you can use the same setup, +breakpoints, etc. for many debugging sessions. * New native configurations @@ -32,6 +67,26 @@ Pyramid pyramid-*-* ARM RISCix arm-*-* (as host) Tahoe tahoe-*-* +Configurations that have been declared obsolete will be commented out, +but the code will be left in place.
