[Qemu-devel] [PATCH v2 0/2] monitor+disas: Remove uses of ENV_GET_CPU

[Peter Crosthwaite <crosthwaitepeter@gmail.com>]

Neither the monitor or disassembly core has a good reason to navigate from an
env pointer to a cpu pointer. Disas should not need env awarness at all, that
is removed in P2.

The monitor is trickier, the env is still needed by some #ifdef switched target
specific code but all common code only needs to trade in CPU pointers. As the
monitor always has access to a CPU pointer naturally, remove ENV_GET_CPU usages
(P1).

This is related to my multi-arch work, where the goal is to minimise use of
architecture defined global definitions, ENV_GET_CPU being a major headache in
that whole effort. The longer term goal is to limit ENV_GET_CPU use to genuinely
architecture specific code.

But I think these two patches stand in their own right, so sending ahead of the
motherload series. This brings both modules closer to common-oby-y'ification.

First RFC for multi arch is avaiable here:

https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg01771.html

The two patches are done together to avoid a conflict with monitor_disas which
is touched by both patches. If one patch gets acked, the other nacked then
either can be merged independently with trivial edits.

Changed since v1:
Addressed RH and Andreas comments on P1.
