re PR tree-optimization/18507 (block_defs_stack varrray should not be GC'ed)
2004-11-19 Andrew Pinski <pinskia@physics.uc.edu>
PR tree-opt/18507
* tree-flow.h (tree2): Typedef because there is already a VEC(tree).
Define a VEC(tree2) for head.
(register_new_def): Change second argument to be a VEC(tree2).
* tree-ssa-dom.c (block_defs_stack): Change to be a VEC(tree2).
(tree_ssa_dominator_optimize): Initialize block_defs_stack with
the VEC(tree2) function. Also free it before returning.
(dom_opt_initialize_block): Use VEC_safe_push instead of VARRAY_PUSH_TREE
for block_defs_stack.
(restore_currdefs_to_original_value): Use VEC_length instead of
VARRAY_ACTIVE_SIZE. VEC_pop instead of VARRAY_TOP_TREE/VARRAY_POP.
(dom_opt_finalize_block): Use VEC_safe_push instead of VARRAY_PUSH_TREE
for block_defs_stack.
* tree-into-ssa.c (block_defs_stack): Change to be a VEC(tree2).
(rewrite_initialize_block): Use VEC_safe_push instead of VARRAY_PUSH_TREE
for block_defs_stack.
(ssa_register_new_def): Likewise.
(ssa_rewrite_initialize_block): Likewise.
(rewrite_finalize_block): Use VEC_length instead of
VARRAY_ACTIVE_SIZE. VEC_pop instead of VARRAY_TOP_TREE/VARRAY_POP.
(ssa_rewrite_finalize_block): Likewise.
(register_new_def): Change second argument to be a VEC(tree2).
Use VEC_safe_push instead of VARRAY_PUSH_TREE.
(rewrite_blocks): Initialize block_defs_stack with
the VEC(tree2) function. Also free it before returning.
(rewrite_ssa_into_ssa): Likewise.
