We are getting below error when we are trying to compile dpc++ code using clang++ compiler.

Error message:

could you try sycl::pow(...) ?

[steffenlarsen]

If what @zjin-lcf suggests doesn't help, would you be able to provide a reproducer?

@HarishCDev, there were no reply from your side for a while, so I'm going to add a stale label here
