Convert test inputs from the version 1 file format to version 2

[mernst]

This is one of two open PRs that drop support for the obsolete version 1 .decls/.dtrace format: this PR, and #880 (Daikon itself), which contains this PR. #882 (Perl front end) and #883 (scripts) have landed. This PR changes only test inputs, goals, and test drivers, and the current code passes the tests with them.

It converts all 26 version 1 test inputs to version 2:

• tests/daikon-tests/{tcas,schedule,schedule2,pine_mdiep}
• tests/diff-tests/{schedule2,StackAr}
• java/daikon/test/SampleTester.decls
• java/daikon/test/split/targets/{StreetNumberSet,Fib,QueueAr,BigFloat}.decls
• java/daikon/test/dtracediff/*.dtrace.gz

The conversion preserves variable kinds, enclosing variables, isParam (as flags is_param), static constants (as constant records), and the OBJECT parent relations that the version 1 hierarchy code inferred from names. As in version 1, a variable is an array if and only if its rep-type is an array. In a scalar variable's name, [] is a pointer dereference; it becomes [0] (with var-kind field [0]), as Kvasir writes it. The output is the same, except:

• With version 1 input, the old pine_mdiep output printed p->f as p.f and p[0] as p[]; version 2 prints names as declared. After normalizing those, the pine_mdiep output is identical.
• Nine more splitters compile (QueueAr.isFull/dequeue/enqueue, BigFloat.bdiv_). With version 1 input, the generated splitters referred to variables that were never declared, such as this_theArray; with version 2 input, the splitter generator finds the array variable this.theArray[..].

tests/diff-tests/StackAr had been excluded from testing since 2010 and failed ("exit found with no corresponding entry"), because its decls file declares an EXIT ppt before the corresponding ENTER ppt. This PR converts it (moving each ENTER declaration first), reenables it, and regenerates its goal files. Running the reordered version 1 inputs with the current Daikon gives the same output, except that one derived variable prints as post(this.topOfStack)+1 rather than post(this.topOfStack+1). tests/diff-tests/Makefile now runs every subdirectory and stops if a subdirectory's make fails.

It also deletes test inputs that nothing references: SampleTesterGlobal.decls and the RatNum, StackAr, and fuzzy splitter targets, and the version 1 Kvasir goal files SimpleDisambigStructTest.disambig.{decls,dtrace}.goal.

Walkthrough

The pull request converts several Daikon declaration fixtures to version 2.0 records. QueueAr and BigFloat splitter targets add array-variable lookups and use array values from tuples. StackAr and schedule2 expected outputs are revised. The changes also remove selected declaration and specification fixtures and update diff-test make rules and splitter-test setup.

Priority: ➖ Normal

Change: Other

Merge Risk: 🔵 Low · up to 1ca72

The StackAr declarations may misidentify a push argument, but a change to the test output has not been established. This is a bounded fixture concern to resolve or accept before merging.
