See GDB's +remote protocol documentation for details. + +* All targets using the new architecture framework. + +All of GDB's targets have been updated to use the new internal +architecture framework. The way is now open for future GDB releases +to include cross-architecture native debugging support (i386 on amd64, +ppc32 on ppc64). + +* GNU/Linux's Thread Local Storage (TLS) + +GDB now includes support for for the GNU/Linux implementation of +per-thread variables. + +* GNU/Linux's Native POSIX Thread Library (NPTL) + +GDB's thread code has been updated to work with either the new +GNU/Linux NPTL thread library or the older "LinuxThreads" library. + +* Separate debug info. + +GDB, in conjunction with BINUTILS, now supports a mechanism for +automatically loading debug information from a separate file. Instead +of shipping full debug and non-debug versions of system libraries, +system integrators can now instead ship just the stripped libraries +and optional debug files. + +* DWARF 2 Location Expressions + +DWARF 2 Location Expressions allow the compiler to more completely +describe the location of variables (even in optimized code) to the +debugger. + +GDB now includes preliminary support for location expressions (support +for DW_OP_piece is still missing). + +* Java + +A number of long standing bugs that caused GDB to die while starting a +Java application have been fixed. GDB's Java support is now +considered "useable". + * GNU/Linux support for fork, vfork, and exec. The "catch fork", "catch exec", "catch vfork", and "set follow-fork-mode" |
