[Qemu-devel] [PATCH 0/5] Remove CONFIG_QEMU_LDST_OPTIMIZATION

[Richard Henderson]

This patch set is based upon

  git://github.com/rth7680/qemu.git tcg-arm-pull

With the first patch, to convert aarch64 away from the old
ldst helpers, we wean exec-all.h from any knowledge of the
tcg backend implementation.  Which means we no longer need
to involve configure in the backend implementation either.

The structure I've chosen, a TCGBackendData structure that
is (technically) totally private to the backend, is based
on my long-term assumption that many targets would do better
with some sort of constant pool.  Or allowing ia64 to save
data with which it could produce better instruction bundling
across tcg opcodes.

That said, until there is some need for the TCGBackendData
structure to be unique, let's share as much code as we can.
Thus the two helper header files, which allow all of the
boilerplate code for ldst optimization to be shared.
