// The IslCodeGeneration pass takes a Scop created by ScopInfo and translates it
|
|
// back to LLVM-IR using the ISL code generator.
|
|
//
|
|
// The Scop describes the high level memory behaviour of a control flow region.
|
|
// Transformation passes can update the schedule (execution order) of statements
|
|
// in the Scop. ISL is used to generate an abstract syntax tree that reflects
|
|
// the updated execution order. This clast is used to create new LLVM-IR that is
|
|
// computationally equivalent to the original control flow region, but executes
|
|
// its code in the new execution order defined by the changed scattering.
