""" Constants for annotations in the mapping.
The constants defined here are used to annotate the mapping tuples in cuda_to_hip_mappings.py.
They are based on
https://github.com/ROCm-Developer-Tools/HIP/blob/master/hipify-clang/src/Statistics.h
and fall in three categories: 1) type of mapping, 2) API of mapping, 3) unsupported
mapping.

""" Mapping of CUDA functions, include files, constants, and types to ROCm/HIP equivalents

This closely follows the implementation in hipify-clang
https://github.com/ROCm-Developer-Tools/HIP/blob/master/hipify-clang/src/CUDA2HipMap.cpp
and its structure.
There are different maps for fundamental names, include files, identifies, sparse, and
PyTorch specific translations.
Each of the entries in these maps translates a CUDA string to a tuple containing the
ROCm/HIP string, a type and API annotation and - optionally - an annotation if it is not
supported in ROCm/HIP yet.
