This won't help for the problems with MIPS FPU emulation, will it?
Both breakpoints and the FPU emulation in the Linux kernel use
self-modifying code, so there should be a general solution for
both (and more related) problems.
As long as this general solution is missing, the published code
qemu-0.9.0 ...
emulating Debian 2.6.18-4-qemu mipsel ...
errs when gdb 6.4.90-debian (running on the emulated mipsel)
single-steps the user-mode instruction ...
This looks like another instance of Qemu/MIPS doesn't handle
self-modifying code correctly (the break instructions inserted
by gdb
