 ### Identifying HIP Target Platform
 All HIP projects target either AMD or NVIDIA platform. The platform affects which headers are included and which libraries are used for linking.

 ### Identifying the Compiler: hip-clang or nvcc
 Often, it's useful to know whether the underlying compiler is HIP-Clang or nvcc. This knowledge can guard platform-specific code or aid in platform-specific performance tuning.

 - AMD platform
 On AMD platform, HIP uses Radeon Open Compute Common Language Runtime, called ROCclr.

 ROCclr is a virtual device interface that HIP runtimes interact with different backends which allows runtimes to work on Linux , as well as Windows without much efforts.
 
+Note, `HIP_ROCclr` needed to be defined on AMD platform that HIP used ROCclr, only when platform was defined as deprecated `HIP_PLATFORM_HCC`.

 - NVIDIA platform
 On Nvidia platform, HIP is just a thin layer on top of CUDA.
 On non-AMD platform, HIP runtime determines if nvcc is available and can be used. If available, HIP_PLATFORM is set to nvcc and underneath CUDA path is used.
