## VectorFunctionShape class
The object `VectorFunctionShape` contains the information about the
kind of vectorization available for an `llvm::Call`.
The object `VectorFunctionShape` must contain the following information:
1. Vectorization Factor (or number or concurrent lanes executed by the
SIMD version of the f...

...LinearValPos,

};
The enum is used to classify the `ParameterType`, a class that is attached to each parameter and describes things like uniformity, linearity (with and without modifiers). The list of parameter types is then stored in the VectorFunctionShape:
struct VectorFunctionShape {
unsigned VF; // Vectorization factor
bool IsMasked;
bool IsScalable;
ISAKind ISA;
std::vector<ParamType> Parameters; };
Here OpenMP is used to classify the parameter types (OMP_*), but nothing prevent...

RFC: Interface user provided vector functions with the vectorizer.
For example, Type 2 case, scalar-foo used call by value while vector-foo used call by ref. The question Johannes is asking is whether we can decipher that after the fact, only by looking at the two function signatures, or need some more info (what kind, what's minimal)? I think we need to list up cases of interest, and for each vector ABI of interest, we need to work on the requirements and
