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.
