Not natively, but AdaptiveCpp (previously hiSycl, then OpenSycl) has a single source single compiler pass, where they basically store LLVM IR as an intermediate representation. https://github.com/AdaptiveCpp/AdaptiveCpp/blob/develop/doc/compilation.md https://github.com/AdaptiveCpp/AdaptiveCpp/blob/develop/doc/... Performance penalty was within ew precents, at least according to the paper (figure 9 and 10) https://cdrdv2-public.intel.com/786536/Heidelberg_IWOCL__SYCLCon_2023_paper_2566-1.pdf https://cdrdv2-public.intel.com/786536/Heidelberg_IWOCL__SYC...
