Stella Laurenzo 48a0b0ec7f NFC: Move CPATypeInference to Typing directory. 2020-07-04 16:56:09 -07:00
Stella Laurenzo 051d088161 NFC: Move CPA typing analysis down a directory. 2020-07-04 16:40:02 -07:00
Stella Laurenzo 6a50efd046 Extend the CPA type inference to work on numpy types/ops. 
* Adds an op interface for adding CPA constraints.
* Adds a type conversion hook for handling built-in types (that we can't have adopt our interface).
* Converts tensor<> to object(!Tensor, [e:<type>]) just like NdArray.
* Implement a few numpy ops far enough to do dtype inference for simple sequences.

Stella Laurenzo 34861b18f4 Add NdArray type inference conversion. 2020-07-03 16:38:10 -07:00
Stella Laurenzo 4a2f7c0b5f Add constraint propagation and tracking of node members. 2020-07-03 13:29:52 -07:00
Stella Laurenzo 1a13c38033 More progress on CPA. 
* Added transitivity propagation rules.
* Fixed up some copy-n-paste inversions from the old algorithm.

Stella Laurenzo 74b8bed7e3 Unique CPA type and constraints to enable comparison by pointer during propagation. 2020-07-02 17:07:02 -07:00
Stella Laurenzo a257da46e2 Introduce a type interface for mapping to CPA types. 
* Currently just simplifies the logic for UnknownType -> TypeVar.

Stella Laurenzo b0604684ba NFC: Move CPA support down into it's own directory. 2020-07-02 11:31:23 -07:00
Stella Laurenzo 92190176fb Add skeleton of pass to do modified PCA type inference. 2020-06-30 20:57:09 -07:00
Stella Laurenzo b21b5322f6 Basicpy conversion to IREE+std skeleton and first conversions. 
* Conversions to std for numeric binary expressions, numeric to_boolean, and numeric comparisons.
* Added folders to constant ops to comply with requirements of the pass system.
* Extended the frontend with parameter/result annotation processing for primitives (can specify types for function arguments).
* Added (empty) directory/sources for IREEVM conversions. These are only enabled if IREE is enabled.

Stella Laurenzo 750541e9a9 Extend type inference so that it works across conditional boundaries. 
* The implementation is still limited but gives something to build on.

Stella Laurenzo e3fd22a035 Add a (very) basic type inference pass for basicpy. 
For simple programs, this gets us enough typing to lower to real backends.

Stella Laurenzo 3e58d8fe37 Add skeleton of type inference pass. 2020-06-10 14:48:22 -07:00
