This has already been done multiple times without using LLMs. For HIP, there are tools like hipify-clang, hipify-perl, and hipify (the Python-based tool in PyTorch). For SYCL, there is SYCLomatic. The devil is in the details, though; at some point, all projects encounter non-portable code due to different instruction sets. For example, if the hardware does not support Warpgroup Level Multiply-and-Accumulate or a specific minifloat format, it is actively harmful to translate the code 'as is.' These platforms require software redesign, which is not something that LLMs are currently capable of handling.
