Hi, We're missing a bunch of mips trapframe/etc handling code in the upstream gdb for freebsd/mips. There's freebsd/alpha upstream, but not mips. i use the gdb in a qemu VM to diagnose freebsd/mips related issues. I'm mainly afraid of having no sensible replacement - we can't (yet) cross compile gdb easily for mips, we can't (yet) easily cross compile a gdb /stub/ to remote debug mips, and upstream gdb / our port doesn't support freebsd/mips. If someone gdb cluey could pull out the freebsd/mips specific gdb code and at least get it into the port as a set of patches, that'd be a great start. I'm happy to try and work with others to get that patchset upstreamed into gdb (once I finally sign the FSF documentation, sigh.) Thanks, -adrian
