Linter error + Question: So the opencl intrinsics are declared here, shouldn't the mappping also change? Or was the mapping done in the previous PR without declaration which would have resulted in compilation issues? If it's the latter we need to adjust testing |
The use-compiler-builtins patch removed OpenCL single-precision built-in declarations, thought to be redundant, but this silently broke HIP intrinsics which relied on them. HIP intrinsics that called single-precision OpenCL built-ins previously, called double-precision variants after the patch (perf. drop, especially on devices without double support). Fix by bringing the OpenCL single-precision built-in declarations where they are needed.

Lint fix.
This patch brings the mapping to the state it was before #763 PR. |

The use-compiler-builtins patch unintentionally redirected HIP single precision intrinsic calls to double precision compiler/OpenCL built-ins.
