The other approach is a memory page discard mechanism - which
obviously requires more code changes than zeroing freed pages.
The advantage is that we don't take the brute-force and CPU intensive

Hi Peter,
Would QEMU developers be interested in integrating this TCG compilation
functionality that I have been working on into later releases of QEMU? The
patch I have right now breaks the original emulation but if there is some
interest in supporting static compilation into TCG in the future,

These patches apply on top of qemu.git master, and can also be obtained from:
git://github.com/mdroth/qemu.git visitor-fixed-width-v2
CHANGES SINCE V1:
- unit tests: covert QmpOutputVisitor qobject to json before passing it to
QmpInputVisitor*. I.e., actually do the serialization :)
-
This adds visitor interfaces for fixed-width integers types.
Implementing these in visitors is optional, otherwise we fall back to
visit_type_int() (int64_t) with some additional bounds checking to avoid
integer overflows for cases where the value fetched exceeds the bounds
of our target C type.

JSON numbers can be interpreted as either integers or floating point
values depending on their representation. As a result, QMP input visitor
might visit a QInt when it was expecting a QFloat, so add handling to
account for this.

Are you sure? Most devices are BIG or
Currently we test our visitors individually, and seperately for input
vs. output. This is useful for validating internal representations
against the native C types and vice-versa, and other visitor-specific
testing, but it doesn't cover the potential use-case of using visitor
pairs for
