r123336 - in /branches/sel-sched-branch/gcc: Ch...


Author: abel
Date: Thu Mar 29 17:17:13 2007
New Revision: 123336

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=123336
Log:
        * sel-sched.c (generate_bookkeeping_insn): Remove unneeded
        conditions when checking if bookkeeping insn can be generated in
        existing block and fix coding.
        (init_seqno_1): Remove assert.
        (fill_insns): Remove unneeded moving of boundary. In rare case of
        generating bookkeeping insn at the block above floating bb header
        split this (upper) block after place_to_insert generating new
        floating bb header that way.
        (sel_sched_region_1): Implement rescheduling of pipelined code.
        * sel-sched-ir.c (sel_split_block): Added second parameter meaning
        instruction, after which basic block should be splitted.
        * sel-sched-ir.h: Correct declaration.
        * sel-sched-dump.c (sel_print_insn): Check if INSN_VI is present
        before referencing VINSN_SCHED_TIMES.
        * common.opt (flag_sel_sched_reschedule_pipelined): New flag to
        reschedule pipelined code without pipelining after scheduling
        region.
        * sched-deps.c (sched_analyze_insn): Replace TRUE_BARRIER with
        MOVE_BARRIER to generate anti instead of true dependencies for
        JUMP followed with a BARRIER.
