== This Week ==
* TCWG-120 (8/10)
- Resolved df issue in my patch, sent to tcwg list for review,
- VRP makes the issue latent at -O2. Reproducible with -fno-tree-vrp
- Taking another approach to run a "specialized" combine pass before
combine pass that
folds arm_andsi3_insn/arm_cmpsi_insn to zeroextracsi_compare0_scratch
or andsi3_compare0_scratch without relying on combine.
