[Qemu-devel] [PATCH 0/7] Define "deposit" tcg operation, v2

[Richard Henderson]

Changes since v1:
  * No attempt to pack pos+len into one operand.  Updated backends
    to match this change.

  * Example in the README is a bit more complex.

  * Define an official tcg_scratch_alloc routine, used by the i386
    target for the case in which we need a scratch register.  I had
    said that triggering this wasn't possible with mainline, but I
    was wrong.  The rlwimi example I posted in the other thread hits
    this case.

Aurelien suggested using a shorter name like "dep", but I think that
would be more confusing than not.  This opcode is not really used
enough to warrent cropping 4 characters, in my opinion.
