2014-10-24 Richard Biener <rguenther@suse.de> * genmatch.c (expr::gen_transform): Use fold_buildN_loc and build_call_expr_loc. (dt_simplify::gen): Drop non_lvalue for GIMPLE, use non_lvalue_loc to build it for GENERIC. (decision_tree::gen_generic): Add location argument to generic_simplify prototype. (capture_info): New class. (capture_info::capture_info): New constructor. (capture_info::walk_match): New method. (capture_info::walk_result): New method. (capture_info::walk_c_expr): New method. (dt_simplify::gen): Handle preserving side-effects for GENERIC code generation. (decision_tree::gen_generic): Do not reject operands with TREE_SIDE_EFFECTS. * generic-match.h: New file. * generic-match-head.c: Include generic-match.h, not gimple-match.h. * match.pd: Add some constant folding patterns from fold-const.c. * fold-const.c: Include generic-match.h. (fold_unary_loc): Dispatch to generic_simplify. (fold_ternary_loc): Likewise. (fold_binary_loc): Likewise. Remove patterns now implemented by generic_simplify. * gimple-fold.c (replace_stmt_with_simplification): New function. (fold_stmt_1): Add valueize parameter, dispatch to gimple_simplify. (no_follow_ssa_edges): New function. (fold_stmt): New overload with valueization hook. Use no_follow_ssa_edges for the overload without hook. (fold_stmt_inplace): Likewise. * gimple-fold.h (no_follow_ssa_edges): Declare. From-SVN: r216631 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with 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/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
