<url href="https://github.com/bsdjhb/gdb/tree/freebsd-7.9.0-kgdb">Port of kgdb to gdb 7.9</url>
</links>
<body>
<p>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.</p>
<p>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).
