        PR tree-optimization/33576
        * testsuite/gcc.dg/tree-ssa/pr33576.c: New.
        * tree-loop-linear.c (linear_transform_loops): Call remove_iv.
        * lambda.h (lambda_loopnest_to_gcc_loopnest): New parameter.
        (remove_iv): Declared.
        * lambda-code.c (remove_iv): Not static.
        (lambda_loopnest_to_gcc_loopnest): New parameter remove_ivs.
        Don't remove ivs there, save ivs in the buffer.
