Add countbits 16-bit and 8-bit support (#6433) (#6897)

2025-05-05T22:30:33+00:00

Change adds 16-bit and 8-bit support for countbits intrinsic. In cases where a backend's native counbits lacks support, support is emulated. New tests are added for 16-bit and 8-bit support. Additional testing added for 32-bit and minor updates made to 64-bit countbits.

Implement 64bit countbits intrinsic (#6433) (#6845)

2025-04-19T11:33:27+00:00

Change modifies the countbits intrinsic to use generics in order to support 64bit countbits on select platforms where this is supported. On platforms where this is not natively supported, we emulate by converting the 64-bit type into a uint2 (metal and spir-v). This should align with the implementation of other uint64_t intrinsics such as abs, min, max and clamp. Added new countbits64 test to verify changes. Updated documentation for 64bit-type-support.html
