Merged requested to merge da15siwa/pystencils:loop_step into master
This MR introduces some additions and fixes for generating CPU loops with step sizes > 1:
- The CPU
create_kernelfunction now exposes a flag to disable the double field write check
get_base_buffer_indexto use pure integer arithmetic, and corrected the computation of the buffer base index to correctly incorporate loop step sizes. Added test case to check correctness.
- Added rudimentary
evalffunctionality to integer division sympy function
int_div(its absence lead to an infinite recursion during code generation).
- Added correct printing of integer-typed expressions in
