LowPriorityImplicits / EmbeddedControls (i.e. parents of Predef) - * 3. the rest - * - * 1 is to avoid cyclic reference errors. - * 2 is due to the following. When completing "Predef" (*), typedIdent is called - * for its parents (e.g. "LowPriorityImplicits"). typedIdent checks whether - * the symbol reallyExists, which tests if the type of the symbol after running - * its completer is != NoType. - * If the "namer" phase has not yet run for "LowPriorityImplicits", the symbol - * has a SourcefileLoader as type. Calling "doComplete" on it does nothing at - * all, because the source file is part of the files to be compiled anyway. - * So the "reallyExists" test will return "false". - * Only after the namer, the symbol has a lazy type which actually computes - * the info, and "reallyExists" behaves as expected. - * So we need to make sure that the "namer" phase is run on predef's parents - * before running it on predef. - * - * (*) Predef is completed early when calling "mkAttributedRef" during the - * addition of "import Predef._" to sourcefiles. So this situation can't - * happen for user classes. - * - */ - private def coreClassesFirst(files: List[SourceFile]) = { - val goLast = 4 - def rank(f: SourceFile) = { - if (f.file.container.name != "scala") goLast - else f.file.name match { - case "LowPriorityImplicits.scala" => 2 - case "StandardEmbeddings.scala" => 2 - case "EmbeddedControls.scala" => 2 - case "Predef.scala" => 3 /* Predef.scala before Any.scala, etc. */ - case _ => goLast - } - } - files sortBy rank - } } // class Run def printAllUnits() { print("[[syntax trees at end of %25s]]".format(phase)) - afterPhase(phase)(currentRun.units foreach { unit => + exitingPhase(phase)(currentRun.units foreach { unit => nodePrinters showUnit unit }) } @@ -1739,7 +1614,7 @@ class Global(var currentSettings: Settings, var reporter: Reporter) */ def showDef(fullName: Name, declsOnly: Boolean, ph: Phase) = { val boringOwners = Set[Symbol](definitions.AnyClass, definitions.AnyRefClass, definitions.ObjectClass) - def phased[T](body: => T): T = afterPhase(ph)(body) + def phased[T](body: => T): T = exitingPhase(ph)(body) def boringMember(sym: Symbol) = boringOwners(sym.owner) def symString(sym: Symbol) = if (sym.isTerm) sym.defString else sym.toString @@ -1785,7 +1660,7 @@ class Global(var currentSettings: Settings, var reporter: Reporter) val printer = new icodes.TextPrinter(null, icodes.linearizer) icodes.classes.values.foreach((cls) => { val suffix = if (cls.symbol.hasModuleFlag) "$.icode" else ".icode" - var file = getFile(cls.symbol, suffix) + val file = getFile(cls.symbol, suffix) // if (file.exists()) // file = new File(file.getParentFile(), file.getName() + "1") try { @@ -1795,7 +1670,7 @@ class Global(var currentSettings: Settings, var reporter: Reporter) informProgress("wrote " + file) } catch { case ex: IOException => - if (opt.debug) ex.printStackTrace() + if (settings.debug.value) ex.printStackTrace() globalError("could not write file " + file) } }) @@ -1806,14 +1681,11 @@ class Global(var currentSettings: Settings, var reporter: Reporter) // and forScaladoc default to onlyPresentation, which is the same as defaulting // to false except in old code.
