Detailed Description
Counts the total number of OpenMP canonical nested loops, including the outermost loop (the original loop).
PRECONDITION of this visitor is that it must be invoked from the original loop to be analyzed. The traversal stops for Decl's and Expr's given that they may contain inner loops that must not be counted.
Example AST structure for the code:
int main() { #pragma omp fuse { for (int i = 0; i < 100; i++) { <– Outer loop []() { for(int j = 0; j < 100; j++) {} <– NOT A LOOP (1) }; for(int j = 0; j < 5; ++j) {} <– Inner loop } for (int r = 0; i < 100; i++) { <– Outer loop struct LocalClass { void bar() { for(int j = 0; j < 100; j++) {} <– NOT A LOOP (2) } }; for(int k = 0; k < 10; ++k) {} <– Inner loop {x = 5; for(k = 0; k < 10; ++k) x += k; x}; <– NOT A LOOP (3) } } } (1) because in a different function (here: a lambda) (2) because in a different function (here: class method) (3) because considered to be intervening-code of non-perfectly nested loop Result: Loop 'i' contains 2 loops, Loop 'r' also contains 2 loops.
