From e288e2f51bed5d45a8a89479bc2f98337bc18c80 Mon Sep 17 00:00:00 2001 From: Andrew MacLeod Date: Thu, 25 Nov 2004 20:24:59 +0000 Subject: re PR tree-optimization/18587 (build_v_may_defs and build_vuses can be improved when adding) 2004-11-25 Andrew Macleod PR tree-optimization/18587 * tree-flow-inline.h (mark_call_clobbered, mark_non_addressable): Flag call clobbered caches as invalid. * tree-ssa-operands.c (ssa_call_clobbered_cache_valid): New. Flag indicating whether the call clobbered operand cache is valid. (ssa_ro_call_cache_valid): New. Flag indicating whether the pure/const call operand cache is valid. (clobbered_v_may_defs, clobbered_vuses, ro_call_vuses): New. cached list of operands for cached call virtual operands. (clobbered_aliased_loads, clobbered_aliased_stores, ro_call_aliased_load): New. flags caching whether alias bits are to be set in call stmt's. */ (fini_ssa_operands): Remove call operand caches if present. (get_expr_operands, get_asm_expr_operands, get_indirect_ref_operands): Pass stmt annotation to add_stmt_operand. (get_call_expr_operands): Add call clobbered variables first. (add_stmt_operand): Take stmt annotation rather than stmt as a param. (add_call_clobber_ops, add_call_read_ops): Use the call operand cache if it is valid, otherise fill the cache. * tree-ssa-operands.h (ssa_clobbered_cache_valid): Declare extern. * tree-flow.h (struct var_ann_d): Add in_vuse_list and in_v_may_def_list bits. * tree-ssa-operands.c (cleanup_v_may_defs): New. Clear the in_list bits for the v_may_def elements and empty the operand build array. (finalize_ssa_vuses): Use cleanup_v_may_defs and remove redundant VUSES by checking the in_v_may_def_list bit. (append_v_may_def, append_vuse): Use the in_list bit rather than scanning the array for duplicates.
