From: "sayle at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/30391] [4.3 regression] ICE at -O1 with conditional expressions and GIMPLE_MODIFY_STMT Date: Fri, 16 Feb 2007 03:38:00 -0000 [thread overview] Message-ID: <20070216033838.19599.qmail@sourceware.org> (raw) In-Reply-To: <bug-30391-10259@http.gcc.gnu.org/bugzilla/> ------- Comment #10 from sayle at gcc dot gnu dot org 2007-02-16 03:38 ------- Subject: Bug 30391 Author: sayle Date: Fri Feb 16 03:38:22 2007 New Revision: 122030 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=122030 Log: PR middle-end/30391 * tree.c (expr_align): Handle MODIFY_EXPR. GIMPLE_MODIFY_STMT should be unreachable. (build2_stat): Allow construction of MODIFY_EXPR at any time. For the time being redirect GIMPLE_MODIFY_STMT to the new (renamed) build_gimple_modify_stmt_stat. (build2_gimple_stat): Rename to... (build_gimple_modify_stmt_stat): Now longer take a CODE argument. Always build a GIMPLE_MODIFY_STMT node. * tree.h (build2_gimple, build2_gimple_stat): Delete. (build_gimple_modify_stmt, build_gimple_modify_stmt_stat): New declarations. * tree-cfg.c (factor_computed_gotos, tree_merge_blocks, gimplify_val): Use build_gimple_modify_stmt instead of build2_gimple. * tree-complex.c (set_component_ssa_name, expand_complex_move, expand_complex_div_wide): Likewise. * tree-ssa-dom.c (record_equivalences_from_stmt): Likewise. * tree-ssa-loop-im.c (schedule_sm): Likewise. * tree-ssa-loop-ivopts.c (rewrite_use_nonlinear_expr): Likewise. * tree-ssa-loop-manip.c (create_iv): Likewise. * tree-ssa-phiopt.c (conditional_replacement, minmax_replacement, abs_replacement): Likewise. * tree-ssa-pre.c (create_expression_by_pieces, poolify_modify_stmt, realify_fake_stores): Likewise. * builtins.c (std_expand_builtin_va_start): Build a MODIFY_EXPR node rather than a GIMPLE_MODIFY_STMT node. (std_gimpify_va_arg_expr, expand_builtin_va_copy, fold_builtin_memset, fold_builtin_memory_op, do_mpfr_sincos): Likewise. (integer_valued_real_p): Handle MODIFY_EXPR, not GIMPLE_MODIFY_STMT. * expr.c (expand_expr_real_1): Handle both MODIFY_EXPR and GIMPLE_MODIFY_STMT. * gfortran.dg/pr30391-1.f90: New test case.
