In theory this bug could associated CaptureOutNodes with the wrong transitively called
callable. However, in practice I could not create a test case that revealed incorrect
behaviour. I've included one such test case in the commit.
I believe that the cause of this is that OutNode::getACall() is not actually used in the
data flow libraries. Instead, DataFlowDispatch::Cached::getAnOutNode is the predicate
which is used to associated OutNode's with DataFlowCall's in practice, and that is always
used in a context that correctly binds the runtime target of the call.
Added basic support for the using stmt, checked stmt, unchecked stmt
Note that the translations do not use the compiler generated element framework and hence they are just rough approximations. For accuracy, in the future their translation should use it.
Added support for continue stmt.
Minimal refactoring of the `TranslatedSpecificJump` classes.
Added a new test file, `jumps.cs` and updated the expected output.
This currently relies on the fact that qltest includes `ql/csharp/ql/src/Metrics` in addition to `ql/csharp/ql/src` on its search path when run internally, which is inconsistent with the other languages. Since this is the only test that relies on it, I'd like to update it and get rid of the extra search root eventually.
The way object creation was translated has been changed: now creations are treated as expressions.
The main motivation for this was the inability to have creation expressions as arguments to
function calls (a test case has been added to showcase this).
All code that dealt with creation expressions has been moved from `TranslatedInitialization.qll` to `TranslatedExpr.qll`.
Some light refactoring has also been done, mainly removing code that was useless after the changes mentioned above.
The foreach was erroneously labelling the `True` and `False` edges as backedges.
Added a case for the compiler generated while in the predicate `getInstructionBackEdgeSuccessor/2`
from the file `IRConstruction.qll` so that only the edges from inside the body are labeled as back edges.
The `raw/internal` folder has been restructured to better enhance code sharing between compiler generated elements and AST generated elements.
The translated calls classes have been refactored to better fit the C# library.
A new folder has been added, `common` that provides blueprints for the classes that deal with translations of calls, declarations, exprs and conditions.
Several `TranslatedX.qll` files have been modified so that they use those blueprint classes.
