Thanks, but I replaceAllUsesWith() - works well, but I still get bug in eraseFromParent(): While deleting: i32 (%class.B*, i32)* %_ZN1B1xEi An asserting value handle still pointed to this value!

The replaceAllUsesWith + eraseFromParent pattern remains correct, but there's

It also occurs on several (different) test cases. I have founded that assershion rises in void ValueHandleBase::ValueIsDeleted(Value *V); Code from function: // All callbacks, weak references, and assertingVHs should be dropped by now. if (V->HasValueHandle) { #ifndef NDEBUG // Only in +Asserts mode... dbgs() << "While deleting: " << *V->getType()

How correctly remove function from module? For example: int f1(int x) { ... a = f2(smth); ... } int f2 (int y) { ... b = f1(smth); ... } I need delete from module both f1 and f2. They haven't uses in other part of module, but I can't delete them with eraseFromParent, because they are use each other. Yours sincerely, Kadysev Mikhail -------------- next part

Virtual call translates into IR like this: %0 = bitcast %class.A* %call to i32 (%class.A*, i32)*** %vtable = load i32 (%class.A*, i32)*** %0 %vfn = getelementptr inbounds i32 (%class.A*, i32)** %vtable, i64 0 %1 = load i32 (%class.A*, i32)** %vfn Is it possible to map pair [StructType, methodIndex(i64 0 in example)] into Function?

Is it possible to merge StructTypes with different names like: %"class.std::allocator.4" = type { i8 } %"class.__gnu_cxx::new_allocator.5" = type { i8 } %"class.std::allocator.0" = type { i8 } %"class.__gnu_cxx::new_allocator.1" = type { i8 } %"class.std::allocator.0.6" = type { i8 } merge into %"class.__gnu_cxx::new_allocator" = type

Hi. I've tried to search the way to write a pass for clang like a pass for opt, but I haven't find it. Is it possible? I need to save class inheritance of the program being processed to external file. Thanks! Yours sincerely, Kadysev Mikhail -------------- next part -------------- An HTML attachment was scrubbed...

Hi. I have such task: to get information about classes of work program (module) form Module (LLVM class), for example in ModulePass. I tried to analyze source code of LLVM architecture related with Module class, but I have not founded any useful information. Thanks!

Hi! I've have Instruction in my code: ... %call6 = call i32 %9(%class.A* %call3, i32 2) ... And I want to get something like this: ... %11 = icmp eq i32 (%class.D*, i32)* %10, @_ZThn4_N1D1xEi br i1 %11, label %12, label %14 ; <label>:12 ; preds = %7 %13 = bitcast %class.A* %call3 to %class.D* %call64 = call i32

Hi. I have a test program: class A { int A; public: virtual void test ( int x ) = 0; }; class B : public A { int B; public: void test ( int x ) {}; }; int main() { A *a = new B(); a->test(1); } We have call site CS: "a->test(1);". CS.getCalledFunction() - return NULL, so we can say that this call site is virtual. My optimization determines, that in this call site

Is it possible to use address of function in case block of switch instruction? I understand that it should be constants only, but in llvm reference i founded that: "The addresses of global variables and functions are always implicitly valid (link-time) constants.

Hi All, I tryed to create a global structured derived declaration in my compiler by: StructType *st = StructType(getGlobalContext(), elements, false); In dump module i didn't find any code needed to declare a new user data type. Is there a instruction to add this class into current module? Cheers, Manuele
