[Qemu-devel] [PATCH v2 0/9] tcg: tidy the type of code_ptr

[Richard Henderson]

Here's a second revision, attempting to take Peter's review on board.

In particular, inlines to hide some of the pointer differencing issues.
I also chose a different name for the type: tcg_insn_unit as suggested
by Jay Foad.
