clava.code.WhileToForStmt Transformation

[joaobispo]

The transformation clava.opt.Inlining is applied after the C/C++ code is normalized to a C/C++ subset designed for code analysis and transformations (clava.opt.NormalizeToSubset).

However, the current C/C++ subset removes for loops, transforming them into while loops. For certain cases, it is preferable to have for loops (e.g. parallelization using OpenMP).

One solution could be disabling the for loop transformation. However, this makes the subset transformation and subsequent use more complex, since now it has to deal with both for and while loops.

An alternative is to create a clava.code.WhileToForStmt transformation pass that re-introduces the for loops at will, from the while loops, which could be similar to the transformations ForToWhileStmt (code) and DoToWhileStmt (code)
