River Riddle	2087bf6386	Remove lowerAffineConstructs and lowerControlFlow in favor of providing patterns. ... These methods don't compose well with the rest of conversion framework, and create artificial breaks in conversion. Replace these methods with two(populateAffineToStdConversionPatterns and populateLoopToStdConversionPatterns respectively) that populate a list of patterns to perform the same behavior.

Nicolas Vasilache	cca53e8527	Extract std.for std.if and std.terminator in their own dialect ... These ops should not belong to the std dialect. This CL extracts them in their own dialect and updates the corresponding conversions and tests. PiperOrigin-RevId: 258123853	2019-07-16 13:43:18 -07:00
Nicolas Vasilache	cab671d166	Lower affine control flow to std control flow to LLVM dialect ... This CL splits the lowering of affine to LLVM into 2 parts: 1. affine -> std 2. std -> LLVM The conversions mostly consists of splitting concerns between the affine and non-affine worlds from existing conversions. Short-circuiting of affine `if` conditions was never tested or exercised and is removed in the process, it can be reintroduced later if needed. LoopParametricTiling.cpp is updated to reflect the newly added ForOp::build. PiperOrigin-RevId: 257794436	2019-07-12 08:44:28 -07:00
