I suppose you tried the gcore command for native GDB on FreeBSD/MIPS and
it worked fine?
It mostly does. I can read the core fine using native GDB on MIPS, but
an x86 GDB doesn't parse the generated core correctly (though it does
parse a native core from the kernel correctly). The issue here though
isn't really a MIPS-specific one. Right now the FreeBSD target-dependent
code uses code from binutils to write out the prpsinfo and prstatus notes
and those write Linux-style "CORE" notes. I have a todo to fix gcore in
gdb to write out "FreeBSD" process and thread status notes instead which
will fix this (along with a separate, but somewhat similar issue with
gdb's gcore on FreeBSD/powerpc).
