            Bug ID: 46085
           Summary: Missing row-major support for llvm.matrix.transpose
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: ajcbik at google.com

The LowerMatrixIntrinsics::LowerTranspose() method asserts on

    assert(InputMatrix.isColumnMajor() &&
           "Row-major code-gen not supported yet!");

when trying to lower the intrinsic for row-major support. For completeness,
this lowering should be implemented as well, similar to some of the other
matrix intrinsics.
