[Qemu-devel] [PATCH v6 00/50] tcg tb_lock removal

[Richard Henderson <richard.henderson@linaro.org>]

I've fixed two bugs within v5 of Emilio's patch set:

 - The step_next_tb patch fixes the "rep movsb" bug that appeared
   when we included CF_COUNT_MASK into CF_HASH_MASK.  We had been
   relying on magic to single-step the next guest insn.

 - The original "allocate optimizer temps with tcg_malloc" patch
   failed testing on arm32 host.  I didn't really look into exactly
   what was wrong because I had an older patch set that touched the
   same portion of the optimizer.

   Thus, an extra 20 patches in the patch set rearranging how temps
   are referenced within the TCG backend.  Some of them have appeared
   on the list before, but it would have been last November.
