Makefile.in (tree-loop-linear.o): Added.
2004-09-08 Daniel Berlin <dberlin@dberlin.org>
* Makefile.in (tree-loop-linear.o): Added.
(OBJS-common): Add tree-loop-linear.o
* common.opt: New flag, ftree-loop-linear.
* timevar.def: New timevar, TV_TREE_LOOP_LINEAR.
* tree-flow.h: Add prototype for linear_transform_loops.
* tree-optimize.c: Add linear transform after vectorization.
* tree-pass.h: Add struct pass_linear_transform.
* tree-ssa-loop.c: Add pass_linear_transform.
* tree-loop-linear.c: New file.
* lambda-code.c: gcc_assertify.
(gcc_loop_to_lambda_loop): Handle all exit tests.
Handle case where we have (invariant >= induction var).
(find_induction_var_from_exit_cond): Ditto.
