Added support for pointers and pointer operations and made sure all loads are correct.
Added support for the unsafe stmt.
Added basic support for the fixed stmt (for now we ignore the pinning).
Fixed a bug where assignments of the form `Object obj1 = obj2` would not generate a load instruction for `obj2` (see `raw_ir.expected`).
Added an extra `Load` for object creations that involve structs. This is because the variable that represents the struct should hold the actual struct, not a reference to it.
Refactored the piece of code that decided if a particular expr needs a load instruction and improved the code sharing between `TranslatedExpr.qll` and `TranslatedElement.qll` by creating 2 predicates that tell if a certain expr does or does not need a load.
Added support for `in`, `out` and `ref` parameters.
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.
The most common reason for the C# autobuilder to fail is because it
cannot determine a single unique .sln or .proj file to build, instead
reporting multiple sln or proj files at the same shortest depth. This
commit changes this to build all such files, rather than reporting an
error.
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.
TTransitiveCaptureCall represents a control flow node that may
transitively call many different callables which capture a variable from
the current scope. Captured variables are represented as synthetic
parameters to the callable, at negative indices. However, each of the
different targets may capture a different subset of variables from the
enclosing scope, so we must include the target along side the CFN in
order to prevent incorrect capture flow.
Added support for continue stmt.
Minimal refactoring of the `TranslatedSpecificJump` classes.
Added a new test file, `jumps.cs` and updated the expected output.
