The NetBSD developers maintain two copies of GDB: * One in the base-system that includes a significant set of local patches. * Another one in pkgsrc whose patching is limited to mostly build fixes. The base-system version of GDB (GPLv3) still relies on local patching to work. I have set a goal to reduce the number of custom patches to bare minimum, ideally achieving the state of GDB working without any local modifications at all. http://blog.netbsd.org/tnf/entry/the_gnu_gdb_debugger_and4 The NetBSD support in GNU binutils and GDB is improving promptly, and the most popular platforms of amd64, i386 and aarch64 are getting proper support out of the box, without downstream patches. The remaining patches for these CPUs include: streamlining kgdb support, adding native GDB support for aarch64, local modifications in the GNU binutils components (especially BFD and ld) and portability enhancements in the dependent projects like libiberty and gnulib. Then, the remaining work is to streamline support for the remaining CPUs (Alpha, VAX, MIPS, HPPA, IA64, SH3, PPC, etc.), to develop the missing generic features (such as listing open file descriptors for the specified process) and to fix failures in the regression test-suite.
