Greetings,
The gdb in the tree seems to be of very limited usefulness these days. It doesn’t seem to work on clang-enabled architectures w/o building -gdwarf-2, it doesn’t seem to work with threaded applications, and on some architectures it doesn’t seem to work at all (mips comes to mind, but it may have been the two binaries I tried).
It seems like we’d be doing our users a favor by applying:
diff -r 8bfca9de870e share/mk/bsd.own.mk
--- a/share/mk/bsd.own.mk
+++ b/share/mk/bsd.own.mk

to the tree, which will turn gdb off by default. It may make more sense to just remove it entirely, but I’m not sure I want to go there just yet in case there are things that I’m missing. I believe that the port will be adequate for all architectures we support, but haven’t tested this directly yet. I do know that on amd64, the port just worked, where the in-tree gdb was an epic fail.
Comments?
