Hi,
On behalf of the QEMU Team, I'd like to announce the availability of the
fourth release candidate for the QEMU 1.6 release. This release is meant
for testing purposes and should not be used in a production environment.

Hi Stefan,
Is there a git tree on which I could rebase my throttling series on top of
the new timers ?

Since commit c658b94f6e8c206c59d02aa6fbac285b86b53d2c, MIPS raises
exceptions when accessing invalid memory. This is not the correct
behaviour for MIPS Malta Core LV, as the GT-64120A system controller
just ignore undecoded access. This feature is used by the Linux kernel
to probe for some devices.

Some guest env are small enough to reach the tlb with only a 12-bit addition.

Handle small positive and negative numbers early. Check for logical
immediates. Check if using MOVN for the first set helps.

The difference being that INSN_* has been pre-shifted into place.
This should result in less runtime shifting of constants.
The patch could be split into smaller pieces for clarity...

Use signed 25-bit operands, because two 12-bit operations is
smaller than movz+movk+add.

Several of these patches need cleaning up, but brings the state of
the port in line with the other targets.
The last patch is dependant on another patch set I've got in the
queue for 1.7 (http://patchwork.ozlabs.org/patch/264736/), but is
otherwise independant.
The patch set is at git://github.co
