Summary:
Add basic translation for C++ `new` keyword.
Currently, it's modeled as simple `malloc` call.
Following constructs are still not working properly:
- array new `new [size_expr]`
- run initializer attached to `new` (such as `new int(5)`)
- `delete[]`
Summary:
1. Unify the code now that MemberExpr has more information available and it can be shared with ObjCIvarRefExpr
2. Use type from decl_ref instead of expression type. For methods, expression type is useless (`<bound something something`>). For fields it should be the same
Summary:
The methods in objc can have the same name in the same class, but one be instance and the other class,
so that we need to take the instance flag into account when defining unique names for ObjC methods.
Summary:
This commit is the result of
`find infer/src -name '*.ml' -or -name '*.mli' -exec ocp-indent -i \{\} \;`
and
`INFER_CHECK_COPYRIGHT=1 InferPrint`
Summary:
In preparation for C++ methods, we need to have type with
class, method, mangled (for overloading?)
1. Change objc method to support it
2. Do some renames to be less confusing
Summary:
In objC we already prefix field names with classes.
It's better to make it consistent since it'll allow
us to share more code between C++ and objC
Summary:
This makes infer C frontend compatible
with new scheme for naming which has:
1. plain name (like 'fun')
2. qualified name (reversed list like ['fun', 'class', 'top_class', 'namespace'])
Summary:
@public
Add support for default function arguments.
As a side change - always create cmethod_signature for a function
Test Plan:
1. Call function with default parameter and confirm that it gets parsed and reports null dereference (B5 but still). It didn't before.
2. Created a test case
Summary: @publicThe first argument of builtin calls in C gets translated twice, which is bad if the argument is a side-effecting expression like a function call.
Test Plan: Attached test previously reported a memory leak because the translation introduces an extra call to malloc(), now reports nothing.
Summary:
@public
Translate CXXStaticCastExpr
Test Plan:
Add test, confirm that it gets translated.
Also create example to see that infer reports null dereference with this change:
struct X { int a; };
int main() {
X *x = static_cast<X*>(nullptr); // <- reports now
//X *x = (X*)nullptr; // <- reported before
return x->a;
}
Summary:
@public
Make c frontend understand CXXNullPtrLiteralExpr.
Note that the implementation differs from GNUNullExpr
Test Plan:
Create function that returns nullptr:
int* getPtr() {return nullptr;}
look at specs:
InferPrint infer-out/specs/getPtr\{831F\}.specs
Procedure: getPtr
int *getPtr()

Summary:
@public
Sorting the fields in structs and classes. Was needed in the backend and forgotten.
Fixes the github issue https://github.com/facebook/infer/issues/90.
Test Plan: Added a new test that shows that we now get a spec for the example from the github issue.
