[Qemu-devel] [RFC PATCH v2 0/6] translate: [tcg] Generic translation framework

[Lluís Vilanova]

This series proposes a generic (target-agnostic) instruction translation
framework.

It basically provides a generic main loop for instruction disassembly, which
calls target-specific functions when necessary. This generalization makes
inserting new code in the main loop easier, and helps in keeping all targets in
synch as to the contents of it.

I've only ported i386 as an example to get some feedback, but I'm planning on
porting ARM next to see how well it fits into the current organization.

Changes in v2
=============

* Port ARM and AARCH64 targets.
* Fold single-stepping checks into "max_insns" [Richard Henderson].
* Move instruction start marks to target code [Richard Henderson].
* Add target hook for TB start.
* Check for TCG temporary leaks.
* Move instruction disassembly into a target hook.
* Make breakpoint_hit() return an enum to accomodate target's needs (ARM).
