PR 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. From-SVN: r69401 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
