Use c++14 for building with CMake

    This is getting rid of some warnings, and C++14 is supposed to be
    the default soon anyway.

5 years ago [TableGen] Make sure op in pattern has the same number of arguments as definition
Lei Zhang [Mon, 8 Apr 2019 22:14:59 +0000 (15:14 -0700)]
[TableGen] Make sure op in pattern has the same number of arguments as definition

    When an op in the source pattern specifies more arguments than its definition, we
    will have out-of-bound query for op arguments from the definition. That will cause
    crashes. This change fixes it.

5 years ago De-templatize TensorContractionBase (Linalg example/tutorial)
Nicolas Vasilache [Mon, 8 Apr 2019 22:06:34 +0000 (15:06 -0700)]
De-templatize TensorContractionBase (Linalg example/tutorial)

    TensorContractionBase has become too unwieldy with all the CRTP manipulation once less trivial transformations are implemented.
    This CL drops CRTP for inheritance and uses the same name comparison trick to figure out what to cast into.
    As a byproduct, all the -inl.h files disappear.
    To maintain the separation between directories, a LINALG_STEP variable is introduced
