hipify-perl

hipify-perl is an autogenerated perl-based script which heavily uses regular expressions.

Advantages:

1. Ease of use.

2. It doesn't check the input source CUDA code for correctness.

3. It doesn't have dependencies on 3rd party tools, including CUDA.

Disadvantages:

1. Current disability (and difficulty in implementing) of transforming the following constructs:

   • macros expansion;

   • namespaces:

     • redefines of CUDA entities in user namespaces;

     • using directive;

   • templates (some cases);

   • device/host function calls distinguishing;

   • header files correct injection;

   • complicated argument lists parsing.

2. Difficulties in supporting.
