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
Aurelien Jarno (4):
tcg/optimize: fix known-zero bits for right shift ops
tcg/optimize: fix known-zero bits optimization
tcg/optimize: improve known-zero bits for 32-bit ops
tcg/optimize: add known-zero bits compute for load ops
