* tree-cfg.c (replace_uses_by): Update information stored at loops.
* tree-flow.h (substitute_in_loop_info): Declare.
* tree-scalar-evolution.c (initialize_scalar_evolutions_analyzer):
Ensure that chrec_dont_know and chrec_known have a type.
* tree-ssa-loop-niter.c (substitute_in_loop_info): New function.
From-SVN: r100631
* tree-flow.h (stmt_ann_d): Move aux to ...
(tree_ann_common_d): ... here.
* tree-ssa-loop-im.c (LIM_DATA, determine_invariantness_stmt,
move_computations_stmt, schedule_sm): Update references to
aux.
* tree-vectorizer.h (set_stmt_info, vinfo_for_stmt): Likewise.
* tree-vect-transform.c (vect_create_index_for_vector_ref): Update
call to set_stmt_info.
(vect_transform_loop): Likewise.
* tree-vectorizer.c (new_loop_vec_info, destroy_loop_vec_info):
Likewise.
* tree-vect-analyze.c (vect_analyze_scalar_cycles): Made void instead of
bool.
(vect_mark_relevant): Takes two additional arguments - live_p and
relevant_p. Set RELEVANT_P and LIVE_P according to these arguments.
(vect_stmt_relevant_p): Differentiate between a live stmt and a
relevant stmt. Return two values = live_p and relevant_p.
(vect_mark_stmts_to_be_vectorized): Call vect_mark_relevant and
vect_stmt_relevant_p with additional arguments. Phis are no longer
put into the worklist (analyzed seperately in analyze_scalar_cycles).
(vect_determine_vectorization_factor): Also check for LIVE_P, because a
stmt that is marked as irrelevant and live, cause it's only used out
side the loop, may need to be vectorized (e.g. reduction).
(vect_analyze_operations): Examine phis. Call
vectorizable_live_operation for for LIVE_P stmts. Check if
need_to_vectorize.
(vect_analyze_scalar_cycles): Update documentation. Don't fail
vectorization - just classify the scalar cycles created by the loop
phis. Call vect_is_simple_reduction.
(vect_analyze_loop): Call to analyze_scalar_cycles moved earlier.
* tree-vect-transform.c (vect_create_index_for_vector_ref): Update
call to set_stmt_info.
(vect_get_vec_def_for_operand): Code reorganized - the code that
classifies the type of use was factored out to vect_is_simple_use.
(vectorizable_store, vect_is_simple_cond): Call vect_is_simple_use with
additional arguments.
(vectorizable_assignment): Likewise. Also make sure the stmt is relevant
and computes a loop_vec_def.
(vectorizable_operation, vectorizable_load, vectorizable_condition):
Likewise.
(vectorizable_live_operation): New.
(vect_transform_stmt): Handle LIVE_P stmts.
* tree-vectorizer.c (new_stmt_vec_info): Initialize the new fields
STMT_VINFO_LIVE_P and STMT_VINFO_DEF_TYPE.
(new_loop_vec_info, destroy_loop_vec_info): Also handle phis.
(vect_is_simple_use): Determine the type of the def and return it
in a new function argument. Consider vect_reduction_def and
vect_induction_def, but for now these are not supported.
(vect_is_simple_reduction): New. Empty for now.
* tree-vectorizer.h (vect_def_type): New enum type.
(_stmt_vec_info): Added new fields - live and _stmt_vec_info.
(STMT_VINFO_LIVE_P, STMT_VINFO_DEF_TYPE): New accessor macros.
(vect_is_simple_use): New arguments added to function declaration.
(vect_is_simple_reduction): New function declaration.
(vectorizable_live_operation): New function declaration.
* tree-vect-analyze.c (vect_can_advance_ivs_p): Add debug printout.
(vect_can_advance_ivs_p): Likewise.
* tree-vect-transform.c (vect_update_ivs_after_vectorizer): Likewise.

* reg-stack.c (struct block_info_def): Correct grammar typo.
(compensate_edge): Clean-up. Perform as little work as possible
when src and dest stacks match. Avoid modifying block_info.
Reorder and simplify assertion checks. Avoid unnecessary copying
of regstack structure.
(convert_regs_1): Set the done flag here...
(convert_regs_2): ... instead of here.

register in global_regs.
(rs6000_stack_info): Don't set lr_save_p just because Darwin
PIC reg used.
(rs6000_emit_prologue): Save LR in R0 around Darwin PIC setup,
if not done by lr_save_p.
* config/rs6000/rs6000.md (insnv1_internal1): Back out 05-18 patch.
Use rotate instead of ashift.
(call_indirect_nonlocal_sysv): Prefer CTR to LR.
