C++17 by default

✔️ (PR)

Builtin changes: ctz(), clz()

❌

Remove *_class types

❌

const return type for read accessor operator[]

❌

Remove buffer API for unique_ptr

❌

Replace program class with module

❌

Add kernel_handler

❌

explicit queue, context constructors

✔️ (PR)

Only require C++ trivially copyable for shared data

✔️

Has always worked thanks to CUDA/HIP toolchain

Update group class with new types/member functions

❌

Remove nd_item::barrier()

❌

Replace mem_fence with atomic_fence

❌

Add vec::operator[],unary +,-, static constexpr get_size()/get_count()

✔️ (PR)

buffer, local accessor are C++ ContiguousContainer

❌

Replace image with sampled_image, unsampled_image

❌

All accessors are placeholders

✔️ (PR)

Use single exception type derived from std::exception

❌

Default asynchronous handler should terminate program

✔️ (PR)

Kernel invocation APIs take const reference to kernels, kernels must be immutable

❌

Queue constructor accepting both device and context

✔️ (PR)

Simplified parallel_for API

❌

Clarified names for device specific info queries

❌

Address space changes, generic address spaces

❌

Partially, we have always had generic address spaces because of CUDA/HIP

Updated multi_ptr interface

❌

Remove OpenCL types, cl_int etc

✔️

hipSYCL has stopped supporting them a long time ago
