>* Investigate how to expand conditional compare GIMPLE to RTL and emit asm.

I think maybe we should start adding target specific expanders.  Then all you 
need to do is take that expander and when you get a COND_EXPR and then looks at 
TRE provided information which then can exapnd the conditional compare without 
adding a new tree code.  Note I think this should be discussed on the GCC list 
directly anyways rather than on the linaro form because it is more likely be 
accepted if talked about there.

Thanks,
Andrew

Subject: [ACTIVITY] Week 12

Summary:
* Send out shrink-wrap related patches for review.
* Investigate how to add a new tree code.

Details:
1. Fix lp:1157050 and lp:1107659 for Linaro toolchain binaries.
2. Test shrink-wrap dwarf/unwind info and send out the patches for review.
3. Make progress on conditional compare support. With some hard-codes
in gcc, it can gimplify a small case to conditional compare on tree
and no assert until expand.

Plan:
* Investigate how to expand conditional compare GIMPLE to RTL and emit asm.

Planned leaves:
* March 31.
* April 4-8.

Best Regards!
