gcc : ChangeLog.tree-ssa tree-dfa.c tree-flow.h
tree-ssa.c tree.h
Log message:
* tree-dfa.c (create_phi_node): Clear PHI_REWRITTEN on all new PHIs
(remove_all_phi_nodes_for): Set PHI_REWRITTEN on any PHIs which are
not removed.
* tree-ssa.c (rewrite_add_phi_arguments): Check the PHI node itself
to see if it has already been rewritten.
* tree.h (PHI_REWRITTEN): New accessor macro.
(struct phi_node): New field rewritten.
* tree-flow.h (struct bb_ann_d): New field num_preds.
* tree-dfa.c (create_phi_node): Get the number of predecessors from
the block's annotation.
* tree-ssa.c (rewrite_into_ssa): Compute number of preds for each
block and store it into the block's annotation.
(insert_phi_nodes_for): Get the number of preds for each block
from the block's annotation.
* tree-ssa.c: Remove parallel lifetime analysis code from April 2003.
(def_blocks_d): Remove PHI_INSERTION_POINTS field.
(compute_global_livein): Accept livein/def bitmaps to use for
life analyis rather than a varray of variables. Callers updated.
Rewritten to compute life information for one variable at a
time instead of several variables at once.
(insert_phis_for_deferred_variables): Remove.
(insert_phi_nodes_for): Lose varray argument. Callers updated.
No longer mess with deferring PHI insertions for variables.
(insert_phi_nodes): No longer need to deal with deferred variables.
Kill everything related to them.
