* Desugar module var and accessor in refchecks/lazyvalsJason Zaugg2015-10-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than leaving it until mixin. The broader motivation is to simplify the mixin phase of the compiler before we get rid of implementatation classes in favour of using JDK8 default interface methods. The current code in mixin is used for both lazy val and modules, and puts the "slow path" code that uses the monitor into a dedicated method (`moduleName$lzyCompute`). I tracked this back to a3d4d17b77. I can't tell from that commit whether the performance sensititivity was related to modules or lazy vals, from the commit message I'd say the latter. As the initialization code for a module is just a constructor call, rather than an arbitraryly large chunk of code for a lazy initializer, this commit opts to inline the `lzycompute` method. During refchecks, mixin module accessors are added to classes, so that mixed in and defined modules are translated uniformly. Trait owned modules get an accessor method with an empty body (that shares the module symbol), but no module var. Defer synthesis of the double checked locking idiom to the lazyvals phase, which gets us a step closer to a unified translation of modules and lazy vals. I had to change the `atOwner` methods to to avoid using the non-existent module class of a module accessor method as the current owner. This fixes a latent bug. Without this change, retypechecking of the module accessor method during erasure crashes with an accessibility error selecting the module var. In the process, I've tweaked a tree generation utility method to wvoid synthesizing redundant blocks in module desugaring.

* Commenting out unused members.Paul Phillips2012-11-191-1/+1
| | | | | | | | | | | | | | | | | | I want to get this commit into the history because the tests pass here, which demonstrates that every commented out method is not only unnecessary internally but has zero test coverage. Since I know (based on the occasional source code comment, or more often based on knowing something about other source bases) that some of these can't be removed without breaking other things, I want to at least record a snapshot of the identities of all these unused and untested methods. This commit will be reverted; then there will be another commit which removes the subset of these methods which I believe to be removable. The remainder are in great need of tests which exercise the interfaces upon which other repositories depend.
* Removed unused imports.Paul Phillips2012-11-061-2/+0
| | | | | | | | | A dizzying number of unused imports, limited to files in src/compiler. I especially like that the unused import option (not quite ready for checkin itself) finds places where feature implicits have been imported which are no longer necessary, e.g. this commit includes half a dozen removals of "import scala.language.implicitConversions".

| | | | | | | | | | | | | | | | | closes #3582: typedTypeDef needs to run in a new typer for TypeDefs with type parameters this was honored when typedTypeDef was called by typed1, but other callers did not this would cause higher-order type parameters to be re-entered in the scope of a method or a class (by the way, should we recycle scopes for higher-order type params? now new scopes are created, symbols entered, and tree's symbols updated) changed some spurious vars to vals review by odersky

| | | | | | | | | As a brief diversion from real work, implemented Damerau–Levenshtein and ran it on trunk to elicit obvious misspellings. Unfortunately they're mostly in places like compiler comments which real people never see, but I fixed them anyway. All those English Lit majors who peruse our sources are sure to be pleased. No review.
