hashcat/OpenCL/m07400-optimized.cl
R. Yushaev 5de004103a Replace kernel parameter lists with macros 
Substitute long parameter lists in ~2900 kernel function declarations
with macros. This cleans up the code, reduces probability of copy-paste
errors and highlights the differences between kernel functions. Also
reduces the size of the OpenCL folder by ~3 MB.
