Hi Michael Kruse, unimodular and non-singular trans, polyhedral trans, dependence and legality of transformations check are enabled, please look up poly.h and ldtran.h for more details. :)
However, convet AST/IR to poly-representation and extract dependence-vector are still not provided yet.

Thank you for sharing!
Regarding xpoly, what kind of analysis/transformation is it capable
of? I could not find an omega-test and mostly unimodular

> xocc is a C compiler that based on XOC infrastructure, XGEN code generator and XOCFE

> Both xocc, XOC, XGEN, and XOCFE are based on BSD license.
> XOC provides multi-level operations, flexibility, and the capability of representing almost all popular languages.
> There are mainly two level IR representations used throughout all phases of the compilation.
> In addition to basic IR representation, XOC also provides IR builder, BB manipulating api, Control Flow Graph(CFG),
> IR lowering, Control Dependent Graph, Dominator Tree, Register SSA, Memory SSA, Agressive Flow Sensitive Alias Analysis,
> Flow Insensitive Alias Analysis, Agressive Field Sensitive Alias Analysis, Interprocedual Analysis Framework, Inliner,
> Dead Code Elimination, Copy Propagation, GCSE, GVN, and a lot of sophisticated control flow and peephole optimizations.
> Moveover, XOC does not use any std library, it provides all basic algorithm library such Vector, List, Map, Dense Bitset,
> Sparse Bitset, Graph, Mempool, Big-Integer, Linear Algebraic library, Linear Programming Solver.
> XGEN provides a retargetable machine code generator.
> For now, it could generate ARM, x86, PAC code. But, x86 and PAC code generator are not release for temporary.
> XGEN provides IR2OR translator, Pre-Instruction-Schedular, Register Allocation, Post-Instruction-Schedular,
> Instruction Packager and Assembly Printer.
> XOCFE is a C frontend, it could provide AST as output.
> xocc is a driver that compose XOCFE, AST2IR, XOC and XGEN into complete C compiler.
> All features provided by xocc, XOC, XGEN, XOCFE could empower you to develop any compiler and analysis tools.
> More important is, any feedback on the compiler and its components would be much appreciated!
