Author: sandra Date: Sat Jul 10 18:43:29 2010 New Revision: 162043 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=162043 Log: 2010-07-10 Sandra Loosemore <san...@codesourcery.com> PR middle-end/42505 gcc/ * tree-inline.c (estimate_num_insns): Refactor builtin complexity lookup code into.... * builtins.c (is_simple_builtin, is_inexpensive_builtin): ...these new functions. * tree.h (is_simple_builtin, is_inexpensive_builtin): Declare. * cfgloopanal.c (target_clobbered_regs): Define. (init_set_costs): Initialize target_clobbered_regs. (estimate_reg_pressure_cost): Add call_p argument. When true, adjust the number of available registers to exclude the call-clobbered registers. * cfgloop.h (target_clobbered_regs): Declare. (estimate_reg_pressure_cost): Adjust declaration. * tree-ssa-loop-ivopts.c (struct ivopts_data): Add body_includes_call. (ivopts_global_cost_for_size): Pass it to estimate_reg_pressure_cost. (determine_set_costs): Dump target_clobbered_regs. (loop_body_includes_call): New function. (tree_ssa_iv_optimize_loop): Use it to initialize new field. * loop-invariant.c (gain_for_invariant): Adjust arguments to pass call_p flag through. (best_gain_for_invariant): Likewise. (find_invariants_to_move): Likewise. (move_single_loop_invariants): Likewise, using already-computed has_call field.
