Hi, I'm trying to understand how clang keeps track of which declarations are called within a translation unit and decides to codegen their definitions. DeclBase.h has a markUsed to keep track of ODR use, and I think that the decl can be found from the symbol table via ASTContext.h (for example looking up a template via GetQualifiedTemplateName -> getAsTemplateDecl -> setIsUsed ). This is just a result of fumbling around in the dark, I could be totall...

Hello, I recently ran into an issue where I wanted to use dyn_cast with a Multiple Inheritance hierarchy. LLVM’s help page on RTTI claims that it can be done, and that Clang’s Decl and DeclContext implement it; however, when I try to use it I run into odd behavior. Here’s my sample code which doesn’t work: ``` struct Base { void *ptr; bool hasInfo; }; struct Info { int size; static

..._|_|X] automatic static assert *- is adding the static assert needs to be manually or is it done automatically with the declaration of the new bitfield. This is not actually true. There is only a single static_assert for the size of the union in Stmt [1] and the same could be done for the union in DeclBase. > * *[_|_|X] runtime assert* - that a new value set, fits into the the bitfield (without truncation). This is true, I agree here that this is useful. > * *[_|_|X] typed* - as opposed to using a representative type (like `int`) and then cast to the actual required type (like `bool` or...

Been having a bit of a problem with dyn_cast: Suppose I have a class A that inherits from two base classes, both of which support dyn_cast. In order to use dyn_cast on A, I need to do a bunch of extra work: 1) Since dyn_cast uses reinterpret_cast rather than static_cast, the pointer value won't get adjusted by the cast operation, making the pointer invalid. I end up having to redefine

Ehud, can you elaborate on which classes you're trying to change. I know some of the classes already use methods like getSubclassDataFromInstruction() to hide bits from the subclasses. They could probably shift the data too. ~Craig On Fri, Dec 27, 2019 at 9:35 AM Bruno Ricci via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Hi, > > On 26/12/2019 20:53, Ehud Katz via
