[Qemu-devel] [PATCH 00/17] [RFC] static instrumentation

[xscript@gmx.net (Lluís)]

Here's a set of patches with the current state of static
instrumentation.

Hope that this organization will help understanding the point of
it. Patch 9 describes the taken approach for instrumenting during code
generation, which is the main point of this.

Code can also be reached at:
