In particular, ``info float'' now +displays the FP registers in the same format on all x86 targets, with +greater level of detail. + +* Improvements and bugfixes in hardware-assisted watchpoints + +It is now possible to watch array elements, struct members, and +bitfields with hardware-assisted watchpoints. Data-read watchpoints +on x86 targets no longer erroneously trigger when the address is +written. + +* Improvements in the native DJGPP version of GDB + +The distribution now includes all the scripts and auxiliary files +necessary to build the native DJGPP version on MS-DOS/MS-Windows +machines ``out of the box''. + +The DJGPP version can now debug programs that use signals. 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 ARM GNU/Linux arm*-*-linux* @@ -41,6 +41,9 @@ To build GDB, you can just do: make cp gdb/gdb /usr/local/bin/gdb (or wherever you want) +(Building GDB with DJGPP tools for MS-DOS/MS-Windows is slightly +different; see the file gdb/config/djgpp/README for details.) + This will configure and build all the libraries as well as GDB.
