output of __expf()

Open zjin-lcf opened this issue 3 years ago • 4 comments

The tool maps __expf() to sycl::exp(). Native math function may be desired.

Hi @zjin-lcf we need to confirm whether there is a precision issue and we will consider to implement it if no precision issue. Thanks.

Hi, @zjin-lcf @tomflinda. I found that the precision of sycl::exp() and sycl::native::exp() is tha same.

@tangjj11 Are sycl::native::exp() and sycl::exp() the same otherwise ? Thanks.

@zjin-lcf I think it is the same, because sycl::exp() call sycl::native::exp(). Please refer to https://github.com/intel/llvm/blob/sycl/sycl/include/sycl/builtins.hpp#L2498.
