Several improvements to GDB have been merged upstream to GDB's + master branch over the past few months including fixes for + unwinding across signal trampoline frames on x86, removing the + procfs dependency from the gcore command, and support for XSAVE + extensions (such as AVX registers) on x86. These fixes are + already available in the existing devel/gdb port as patches + relative to 7.8.

+ +

In addition, progress has been made on porting kgdb to newer + gdb. Currently only support for the amd64 backend has been + ported, but it is functional both for remote debugging and + against crash dumps. The current port generally has feature + parity with the kgdb in the base system. The plan for kgdb is + to fix it to always include all platform targets (so that it + always supports cross debugging for remote targets out of the + box). At some point it may also include cross debugging support + for crash dumps as well (this would require changes to libkvm). +

+ + + + +

Tidy the amd64 port of kgdb and finish the i386 port. This + includes fixing these platform-specific targets to work with + cross-debugging for remote targets.

+ + +

Add a KGDB option to the devel/gdb port to include kgdb + support.

+ + +

Port the rest of the platform-specific targets for kgdb.

+ + +

Write a new 1:1-only thread target for FreeBSD that can be + sent upstream.

+ + +

Add support for debugging powerpc vector registers.
