[refbackrt] Scalar arg support
* Adds f32 scalar argument support across the ABI boundary. * Adds support for passing input type / shape information across the ABI boundary * Adds support for parsing / creating input FloatAttr's in `npcomp-run-mlir`pull/197/head

Runtime metadata for a single func.
|
||||
|
||||
TODO: Augment this with information for type/shape checking of arguments.
|
||||
Contains type / shape information for arguments as described below:
|
||||
|
||||
* ArgType(s):
|
||||
Integer value from `CompilerDataStructures.h` for each argument
|
||||
indicating what type it is (e.g. Float, Int, Tensor, Dict, etc.)
|
||||
* ElementType(s):
|
||||
Certain input ArgType's also have an element type (e.g. Tensor<float>,
|
||||
List<int>, etc.)
|
||||
TODO(brycearden): Support nested types (e.g. List<Tensor<float>>)
|
||||
* Rank(s):
|
||||
Integer value indicating the rank for each argument.
|
||||
* Shape(s):
|
||||
Flattened hyper-rectangular representation of the shapes for each argument.
|
||||
Since each shape's size varies based on the Rank, we pad out the shapes
|
||||
to size kMaxRank to make ABI lowering easier. See `LowerToRefbackrtABI.cpp`
|
||||
for details.
|
||||
|
||||
Shapes Example:
|
||||
constexpr int kMaxRank = 6;
|
||||
// func @f(%arg0: f32, %arg1: tensor<5xf32>) would result in...
|
||||
inputShapes = dense<...> : tensor<12xi32>
|
||||
// 2 shapes with 6 elements each so that the LowerToLLVM pass
|
||||
// where only the first `rank` values in each shape are valid.
|
||||
//
|
||||
// can update the struct(s) by just grabbing a pointer at
|
||||
// %shape_ptr = %base + (kMaxRank * argIndex)
|
||||
}];
