[Qemu-devel] [PATCH v7 00/52] tcg queued patches

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

A bit silly to keep calling this "tb_lock removal", since it
doesn't quite, and it has accumulated several additional patches.

Changes since v6:
  * Dropped unnecessary rename of "temps". (Patch 13)

  * Changed how I avoid 0 as a TCGv_{i32,i64,ptr} value.
    Instead of avoiding TCGTemp index 0, use the offset of
    the TCGTemp within TCGContext. (Patches 16-19,21)

  * Fixed icount wrt CF_HASH_MASK.  I strongly suspect this
    fixes any number of icount problems with MTTCG, since we
    relied on unlocked magic code generation. (Patch 24)

  * Merged removal of tb_tc.search from Emilio.  (Patch 38)
  * Added patch 52 from Emilio.
