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()

Михаил wrote: > It is ModulePass with AnalysisUsage of CallGraph Ah, then you'll need to update the CallGraph first. Use "CG.removeFunctionFromModule(F);" before deleting it.

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

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

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 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...

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 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. Can I know that in Module *M Function* F is a method of StructType *st? Also can I know that in this StructType the F has mark "virtual"? Thanks!

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?

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

In my llvm jit project I needed to lookup BB addresses at execution time and then jump to the corresponding BB. A C++ routine called at runtime from IR finds the right BB, gets its BlockAddress and returns it as an i8*. The IR does an indirectbr on this value... Well, not really. The routine returns the address of a BlockAddress node. Is there any way to get the real runtime code address for the

Hi, i ran into a problem when using blockaddress() with a label in another function. It seems to me that LLVM tries to remove the label used in blockaddress because it seems like it is not used, but in fact it may be used somewhere with a indirectbr. I attached a small test-case that produces this error. (The original problem is much more complicated, so i hope the reduced example, which has no

I see. But the block does not necessarily contain dead code. My original problem is more like this: define i32 @main() { entry: %target = bitcast i8* blockaddress(@test_fun, %test_label) to i8* call i32 @test_fun(i8* %target) ret i32 0 } define i32 @test_fun(i8* %target) { entry: indirectbr i8* %target, [label %test_label] test_label: ; assume some code here... br label %ret ret: ret
