[llvm-dev] 回复： Major release of xocc C compiler, 0.9.2, based on BSD license!

[steven.known via llvm-dev]

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
transformations.
