[Qemu-devel] [PATCH 6/6, UPDATE] A cumulative MIPS patchset

[Thiemo Seufer]

[The previous patch had a broken MIPS32R2 bitops implementation,
and was apparently too big to make it to the list. I retry now
with a compressed attachment.]

Hello All,

this patch adds support for all mandatory MIPS32R2 instructions,
rationalizes the instruction decoding to check always 32-bit words,
reduces the number of magic constants in the code, adds a few bits
which make eventually implementation of MIPS64 support and optional
MIPS32 features easier.

The emulated CPU still identifies itself as a MIPS32(R1) 4Kc.
Currently it doesn't throw a RI exception for R2 instructions, this
is useful for Linux userland emulation, and also follows the current
policy which doesn't distinguish between MIPS32R1 instructions and
those of earlier ISAs.
