--- Comment #11 from Bernd Schmidt <bernds at gcc dot gnu.org> 2011-07-15 13:20:17 UTC --- Author: bernds Date: Fri Jul 15 13:20:10 2011 New Revision: 176315 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=176315 Log: Revert 2003-07-10 Eric Botcazou <ebotca...@libertysurf.fr> PR rtl-optimization/11320 * sched-int.h (struct deps) [reg_conditional_sets]: New field. (struct sched_info) [compute_jump_reg_dependencies]: New prototype. * sched-deps.c (sched_analyze_insn) [JUMP_INSN]: Update call to current_sched_info->compute_jump_reg_dependencies. Record which registers are used and which registers are set by the jump. Clear deps->reg_conditional_sets after a barrier. Set deps->reg_conditional_sets if the insn is a COND_EXEC. Clear deps->reg_conditional_sets if the insn is not a COND_EXEC. (init_deps): Initialize reg_conditional_sets. (free_deps): Clear reg_conditional_sets. * sched-ebb.c (compute_jump_reg_dependencies): New prototype. Mark registers live on entry of the fallthrough block and conditionally set as set by the jump. Mark registers live on entry of non-fallthrough blocks as used by the jump. * sched-rgn.c (compute_jump_reg_dependencies): New prototype. Mark new parameters as unused.
