Oldham" Date: Fri, 17 Sep 2004 21:55:02 +0000 Subject: alias.c (find_base_decl): Remove unreachable case '3' block. 2004-09-17 Jeffrey D. Oldham Zack Weinberg * alias.c (find_base_decl): Remove unreachable case '3' block. * expr.c (safe_from_p): Abort if passed a type. * tree-gimple.c (recalculate_side_effects): Abort if passed anything other than an expression. * tree-ssa-pre.c (phi_translate): Return expr immediately if is_gimple_min_invariant is true for it. Reorder cases for clarity. Abort on un-handled tree classes. (valid_in_set): Likewise. * tree.c (tree_code_class_strings): New static data. * tree.h (enum tree_code_class): New. (tree_code_class_strings): Declare. (TREE_CODE_CLASS_STRING, EXCEPTIONAL_CLASS_P, CONSTANT_CLASS_P) (REFERENCE_CLASS_P, COMPARISON_CLASS_P, UNARY_CLASS_P, BINARY_CLASS_P) (STATEMENT_CLASS_P, EXPRESSION_CLASS_P, IS_TYPE_OR_DECL_P): New macros. (TYPE_P, DECL_P, IS_NON_TYPE_CODE_CLASS, IS_EXPR_CODE_CLASS) (checking macros, EXPR_LOCATION, SET_EXPR_LOCATION, EXPR_LOCUS): Update. * tree.def, c-common.def, objc/objc-tree.def: Use tree_code_class enumeration constants instead of code letters. * alias.c, builtins.c, c-common.c, c-format.c, c-lang.c, c-pragma.c * c-typeck.c, cgraphunit.c, convert.c, dbxout.c, dwarf2out.c * emit-rtl.c expr.c, fold-const.c, gimplify.c, lambda-code.c * langhooks.c, langhooks.h, predict.c, print-tree.c, reload1.c, stmt.c * tree-browser.c, tree-cfg.c, tree-chrec.c, tree-complex.c, tree-dfa.c * tree-dump.c, tree-eh.c, tree-gimple.c, tree-inline.c, tree-nested.c * tree-outof-ssa.c, tree-pretty-print.c, tree-sra.c, tree-ssa-ccp.c * tree-ssa-dce.c, tree-ssa-dom.c, tree-ssa-forwprop.c, tree-ssa-live.c * tree-ssa-loop-im.c, tree-ssa-loop-ivopts.c, tree-ssa-operands.c * tree-ssa-phiopt.c, tree-ssa-pre.c, tree-ssa-propagate.c * tree-ssa.c, tree-ssanames.c, tree-tailcall.c, tree.c, varasm.c * config/sol2-c.c, config/arm/arm.c, config/i386/winnt.c * config/pa/pa.c, config/pa/pa.h, config/sh/sh.c, objc/objc-lang.c Update to match. * LANGUAGES: Add note about change. ada: * ada-tree.def: Use tree_code_class enumeration constants instead of code letters. * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c: Update for new tree-class enumeration constants. cp: * cp-tree.def: Use tree_code_class enumeration constants instead of code letters. * call.c, class.c, cp-gimplify.c, cp-lang.c, cxx-pretty-print.c * mangle.c, pt.c, semantics.c, tree.c, typeck.c: Update for new tree-class enumeration constants. fortran: * f95-lang.c, trans-expr.c, trans.c: Update for new tree-class enumeration constants. java: * java-tree.def: Use tree_code_class enumeration constants instead of code letters. * java-gimplify.c, jcf-write.c, lang.c, parse.y: Update for new tree-class enumeration constants. treelang: * treetree.c: Update for new tree-class enumeration constants.
