[Qemu-devel] [PATCH v3 0/4] tcg/optimize: fixes and improvements

[Aurelien Jarno]

This patchset first fixes known-zero bits optimization so that it works         
                   
in more than a few cases, and does some further optimizations for 32-bit
ops and unsigned loads.
                                                                                
                     
v2 -> v3:
- added support for the new INDEX_op_qemu_ld_{i32,i64} opcodes in patch 4

v1 -> v2:                                                                       
                            
- swapped patches 1 & 2                                                         
                   
- Cc:ed qemu-stable for patch 1                                                 
                         
- improved description of patch 2
