| * | SI-6035: Specialization and separate compilation.Grzegorz Kossakowski2012-07-162-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix an issue when specialization wouldn't work properly in a setting where separate compilation was involved. E.g. if you inherit from a class that is specialized and has been compiled separately you might not get proper forwarders generated. A test-case that this commit adds covers that scenario. The root cause of this issue was the fact that SPECIALIZED flag was not pickled. Thanks to recent Flags reorganization (see a9b85db) all that needs to be done is to set the flag before pickling. We choose to that in superaccessors phase because it's a phase that runs before pickling and after type checking (so we can check if given symbol has an annotation). Removed old logic from uncurry that was responsible for setting flags that is not needed anymore because we set them in superaccessors. Review by @axel22 and @paulp.

The resulting natural beauty is evident in the diff of t6028.check. This subsumes the treatment in 0e170e4b that ensured named parameter calls cannot see mangled names; pos/t6028 confirms as much.

You should put your tests in `instrumented/` directory if you are interested in method call counts. Examples include tests for specialization (you want to count boxing and unboxing method calls) or high-level tests for optimizer where you are interested if methods are successfuly inlined (so they should not be called at runtime) or closures are eliminated (so no constructors of closures are called). Check `scala.tools.partest.instrumented.Instrumentation` to learn how to use the instrumentation infrastructure. The instrumentation itself is achieved by attaching a Java agent to the forked VM process that injects calls to profiler. Check `scala.tools.partest.javaagent.ProfilingAgent` for details. --- A few notes on low-level details of this change: * Partest now depends on asm library for byte-code instrumentation (`build.xml`) * Build additional jar called `scala-partest-javaagent.jar` that is used with `-javaagent:` option. (`build.xml`) * Set `-javaagent:` option for all tests in `instrumented/` directory. (`RunnerManger.scala`) * Introduce a new category of tests called `instrumented`. * Add one instrumented test to demonstrate usage and test new infrastructure itself.

The original implementation in SI-5830 (#821) was pretty buggy. [from the doc comment of `collapseGuardedCases`:] Collapse guarded cases that switch on the same constant (the last case may be unguarded). Cases with patterns A and B switch on the same constant iff for all values x that match A also match B and vice versa. (This roughly corresponds to equality on trees modulo alpha renaming and reordering of alternatives.) The rewrite only applies if some of the cases are guarded (this must be checked before invoking this method). The rewrite goes through the switch top-down and merges each case with the subsequent cases it is implied by (i.e. it matches if they match, not taking guards into account) If there are no unreachable cases, all cases can be uniquely assigned to a partition of such 'overlapping' cases, save for the default case (thus we jump to it rather than copying it several times). (The cases in a partition are implied by the principal element of the partition.) The overlapping cases are merged into one case with their guards pushed into the body as follows (with P the principal element of the overlapping patterns Pi): `{case Pi if(G_i) => B_i }*` is rewritten to `case P => {if(G_i) B_i}*` The rewrite fails (and returns Nil) when: (1) there is a subsequence of overlapping cases that has an unguarded case in the middle; only the last case of each subsequence of overlapping cases may be unguarded (this is implied by unreachability) (2) there are overlapping cases that differ (tested by `caseImpliedBy`) cases with patterns A and B are overlapping if for SOME value x, A matches x implies B matches y OR vice versa <-- note the difference with case equality defined above for example `case 'a' | 'b' =>` and `case 'b' =>` are different and overlapping (overlapping and equality disregard guards) Improved by @retronym's feedback in the following ways: - fix patternEquals (it's now quadratic, but correct) - update neg/t6011 to test the improved patternEquals - remove side-effect-in-condition ugliness - introduce isGuardedCase - docs & various code clarity Also closes SI-6048 (duplicate).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Why hand out big blocks of tests to workers. Just put them all in a queue and let the threads consume them when they can. This speeds up partest a fair bit in those not uncommon situations where one worker would end up lagging well behind the others, and drops another 150ish lines of code. Test suite time on my 8-core machine goes from 28:21 to 22:34.

Avoids mystery constants. Makes a whole bunch of new flags be pickled which were not pickled before (more precisely: Everything in InitialFlags with value greater than 1 << 31 which is not in FlagsNotPickled now gets pickled whereas before it wasn't. Among these: VARARGS, IMPLCLASS, SPECIALZED, DEFAULTINIT, SYNCHRONIZED. I am curious how many tickets will get fixed by this change. The first one I noted is t5504, which previously enforced the buggy behavior through a neg check! There are also some build manager check file changes that have to do with the fact that flags now print in a different order for performance reasons.
