[LLVMdev] [RFC] Adding a few more range adaptors

[David Blaikie]

There's been no wholesale effort to add range adapters. Were just adding
them as/when someone feels the need. Feel free to add any you happen n to
wasn't/need.

Personally I think the phi's/non_phi's would be especially helpful over the
existing formulation. (I think there's a similar work in some other APIs
(maybe operands to an instruction?) Where a list is split into two by some
boundary iterator and would be nice as two range accessor's for the
distinct sub ranges and one for the overall range.
