[Qemu-devel] [PATCH 0/5] MIPS(EL) host support

[Aurelien Jarno <aurelien@aurel32.net>]

This patch series add host MIPS(EL) support to QEMU. It is based on the
excellent work from Arnaud Patard [1].

It supports both little and big-endian hosts, and is currently limited
to the o32 abi. It has been mainly developped and tested in system mode 
on a MIPSEL host, but I have verified that both MIPS and MIPSEL hosts 
can boot Debian Installer amd64, arm, i386, mips, mipsel, ppc and sparc,
and can also boot an SH4 kernel. On the user side, I have verified that
basic support (aka starting libc.so.6) works, but there is probably some
more work to do on this side.

I have mainly focused on getting host support fully working, and haven't
written "aggressively" optimised code. There is still space for speed 
improvement, for example by filling the delay slots or using MIPS R2 
instructions (if available) for byte swapping, rotations or bit field 
insertion/extraction (useful for the memory load/store).
