/*===- test/Regression/Transforms/Scalar/DecomposeMultiDimRefs.cpp -----=*
*
* This is a regression test for the DecomposeArrayRefs pass.
* It tests several different combinations of structure and
* array indexes in individual references. It does *not* yet
* sufficiently test type-unsafe operations like treating a
* 1-D array as a 2-D or 3-D array. (multidim.ll in this directory
* tests a simple case of that though.)
