River Riddle [Mon, 3 Jun 2019 19:49:55 +0000 (12:49 -0700)]
Refactor the dialect conversion framework to support multi-level conversions. Multi-level conversions are those that require multiple patterns to be applied before an operation is completely legalized. This essentially means that conversion patterns do not have to directly generate legal operations, and may be chained together to produce legal code.

To accomplish this, moving forward users will need to provide a legalization target that defines what operations are legal for the conversion. A target can mark an operation as legal by providing a specific legalization action. The initial actions are:
* Legal
  - This action signals that every instance of the given operation is legal,
    i.e. any combination of attributes, operands, types, etc. is valid.
* Dynamic
  - This action signals that only some instances of a given operation are legal. This
    allows for defining fine-tune constraints, like say std.add is only legal when
    operating on 32-bit integers.

An example target is shown below:
struct MyTarget : public ConversionTarget {
  MyTarget(MLIRContext &ctx) : ConversionTarget(ctx) {
    // All operations in the LLVM dialect are legal.
    addLegalDialect<LLVMDialect>();

    // std.constant op is always legal on this target.
    addLegalOp<ConstantOp>();

    // std.return op has dynamic legality constraints.
    addDynamicallyLegalOp<ReturnOp>();
  }

  /// Implement the custom legalization handler to handle
  /// std.return.
  bool isLegal(Operation *op) override {
    // Process the dynamic handling for a std.return op (and any others that were
    // marked "dynamic").
    ...
  }

Introduce OpOperandAdaptors and emit them from ODS

When manipulating generic operations, such as in dialect conversion /
rewriting, it is often necessary to view a list of Values as operands to an
operation without creating the operation itself.  The absence of such view
makes dialect conversion patterns, among others, to use magic numbers to obtain
specific operands from a list of rewritten values when converting an operation.
Introduce XOpOperandAdaptor classes that wrap an ArrayRef<Value *> and provide
accessor functions identical to those available in XOp.  This makes it possible
for conversions to use these adaptors to address the operands with names rather
than rely on their position in the list.  The adaptors are generated from ODS
together with the actual operation definitions.

Use fused location for rewritten ops in generated rewrites.

    This does tracks the location by recording all the ops in the source pattern and using the fused location for the transformed op. Track the locations via the rewrite state which is a bit heavy weight, in follow up to change to matchAndRewrite this will be addressed (and need for extra array go away).
