gcc : ChangeLog.tree-ssa domwalk.h tree-flow.h
tree-ssa.c tree-ssa-dom.c
Log message:
* domwalk.h (struct dom_walk_data): New field "global_data".
* tree-ssa-dom.c (tree_ssa_dominator_optimize_1): Initialize new
"global_data" field.
* tree-flow.h (enum need_phi_state): New enumeration.
(var_ann_d): Add bitfield for need_phi_state.
* tree-ssa.c (mark_def_sites_global_data): New structure to hold
global data for mark_def_sites dominator walk.
(mark_def_sites): Revamp to be called via the dominator walker.
(set_def_block): Update need_phi_state for the variable as needed.
(set_livein_block): Similarly.
(rewrite_into_ssa): Use dominator walker to call mark_def_sites.
Delay freeing dominance info. Kill "globals" bitmap.
(insert_phi_nodes): No longer need "globals" bitmap. Use
need_phi_state in variable's annotation to determine if a PHI
may be needed.
