Module melior::dialect::ods::scf

scf dialect.

The scf (structured control flow) dialect contains operations that represent control flow constructs such as if and for. Being structured means that the control flow has a structure unlike, for example, gotos or asserts. Unstructured control flow operations are located in the cf (control flow) dialect.

Originally, this dialect was developed as a common lowering stage for the affine and linalg dialects. Both convert to SCF loops instead of targeting branch-based CFGs directly. Typically, scf is lowered to cf and then lowered to some final target like LLVM or SPIR-V.
