Function `compiler_copy`

fn compiler_copy<T, SIZE: usize>(_src: *const T, _dst: *mut T)

Profiling marker for copy operations.

This function is never called at runtime. When -Z annotate-moves is enabled, the compiler creates synthetic debug info that makes copy operations appear as calls to this function in profilers.

The SIZE parameter encodes the size of the type being copied. It's the same as size_of::<T>(), and is only present for convenience.
