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:
@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

int *getPtr()
