[Qemu-devel] [PATCH v2 00/24] target-sparc improvements |
Date: |

The primary focus of this patch set is to reduce the number of
helpers that modify TCG globals, and thus increase the lifetime
of those globals within each TB, and thus decrease the number
of times that tcg must spill and fill them from backing store.
As a byproduct, I also implement the bulk of the interesting v9 ASIs
inline, thus exposing e.g. the little-endian loads and stores as
simple tcg operations.
The patch set is relative to my outstanding tcg pull request.
For reference, the complete tree can be found at
git://github.com/rth7680/qemu.git tgt-sparc
Changes from v1 to v2:
* Commit message refers to UA2005 instead of UA2011 when
introducing new asi.h defines. (Artyom)
* Drop the MMU_REAL_IDX, and inline handling of ASI_REAL_*.
This appears to be the source of the regression that Artyom
identified wrt ss5 emulation.
