llvm dev - Mar 2014 - [LLVMdev] Legalization code robustness for overflow intrinsics

Hi,

I have a patch for the first "Target Independent Opportunity"
(lib/Target/README.txt), which also resolves PR4917. However, the readme
contains the following line:
> The legalization code for mul-with-overflow needs to be made more robust
before this can be implemented though.

So my question is: how robust is it, or is this an outdated remark?

-- Erik.
