generic.texi (ANNOTATE_EXPR): Document 3rd operand.
* doc/generic.texi (ANNOTATE_EXPR): Document 3rd operand. * cfgloop.h (struct loop): Add unroll field. * function.h (struct function): Add has_unroll bitfield. * gimplify.c (gimple_boolify) <ANNOTATE_EXPR>: Deal with unroll kind. (gimplify_expr) <ANNOTATE_EXPR>: Propagate 3rd operand. * loop-init.c (pass_loop2::gate): Return true if cfun->has_unroll. (pass_rtl_unroll_loops::gate): Likewise. * loop-unroll.c (decide_unrolling): Tweak note message. Skip loops for which loop->unroll==1. (decide_unroll_constant_iterations): Use note for consistency and take loop->unroll into account. Return early if loop->unroll is set. Fix thinko in existing test. (decide_unroll_runtime_iterations): Use note for consistency and take loop->unroll into account. (decide_unroll_stupid): Likewise. * lto-streamer-in.c (input_cfg): Read loop->unroll. * lto-streamer-out.c (output_cfg): Write loop->unroll. * tree-cfg.c (replace_loop_annotate_in_block) <annot_expr_unroll_kind>: New case. (replace_loop_annotate) <annot_expr_unroll_kind>: Likewise. (print_loop): Print loop->unroll if set. * tree-core.h (enum annot_expr_kind): Add annot_expr_unroll_kind. * tree-inline.c (copy_loops): Copy unroll and set cfun->has_unroll. * tree-pretty-print.c (dump_generic_node) <annot_expr_unroll_kind>: New case. * tree-ssa-loop-ivcanon.c (try_unroll_loop_completely): Bail out if loop->unroll is set and smaller than the trip count. Otherwise bypass entirely the heuristics if loop->unroll is set. Remove dead note. Fix off-by-one bug in other note. (try_peel_loop): Bail out if loop->unroll is set. Fix formatting. (tree_unroll_loops_completely_1): Force unrolling if loop->unroll is greater than 1. (tree_unroll_loops_completely): Make static. (pass_complete_unroll::execute): Use correct type for variable. (pass_complete_unrolli::execute): Fix formatting. * tree.def (ANNOTATE_EXPR): Add 3rd operand. ada/ * gcc-interface/trans.c (gnat_gimplify_stmt) <LOOP_STMT>: Pass 3rd operand to ANNOTATE_EXPR and also pass unrolling hints. c/ * c-parser.c (c_parser_while_statement): Pass 3rd operand to ANNOTATE_EXPR. (c_parser_do_statement): Likewise. (c_parser_for_statement): Likewise. cp/ * pt.c (tsubst_expr) <ANNOTATE_EXPR>: Recurse on 3rd operand. * semantics.c (finish_while_stmt_cond): Pass 3rd operand to ANNOTATE_EXPR. (finish_do_stmt): Likewise. (finish_for_cond): Likewise. fortran/ * trans-stmt.c (gfc_trans_forall_loop): Pass 3rd operand to ANNOTATE_EXPR. From-SVN: r255106
