Thanks for the quick response. I wrote some code to search “llvm.dbg.cu” for the function (right before the failed assertion): if (TheCU == nullptr) { errs() << "compile unit: " << TheCU << "\n scopeNode(" << FnScope->getScopeNode() << ") => " << *FnScope->getScopeNode() << "\n"; auto fn = MF->getFunction(); errs() << " fn => " << fn->getName() << "\n"; MDNode *node = nullptr; auto mod = fn->getParent(); au...

...here's another issue I wanted to mention: I have noticed that debugging and inlining don't play very well together. Even if other optimizations are disabled, if I turn on inlining, I get null pointer errors in this piece of code in DwarfDebug::constructInlinedScopeDIE(): *if* (!Scope->getScopeNode()) *return* NULL; DIScope DS(Scope->getScopeNode()); DIE *ScopeDIE = *new* DIE(dwarf::DW_TAG_inlined_subroutine); DISubprogram InlinedSP = getDISubprogram(DS); CompileUnit *TheCU = getCompileUnit(InlinedSP); DIE *OriginDIE = TheCU->getDIE(InlinedSP); assert(OriginDIE &&am...

Hi Paul, Thanks for your response. Let me actually post more details visualizing my case. Assuming that can help. so the IR before the opt tool is running is: ; Function Attrs: nounwind define i16 @main() #0 !dbg !13 { entry: %retval = alloca i16, align 1 ... } ; Function Attrs: inlinehint nounwind define internal void @delay(i16 %d) #4 !dbg !69 { entry: %d.addr = alloca i16,

We have a test case where we are hitting an assertion in the X86 code generator. The assertion is: "Assertion failed: TheCU && "Unable to find compile unit!", file .\..\..\..\lib\CodeGen\AsmPrinter\DwarfDebug.cpp, line 1411" The bitcode is attached. What I am trying to figure out is what is malformed about our debug that is causing this error? This is reproducible

That happens because we create the subprogram below as a context to the “DW_TAG_typedef” that was created as a type to “DW_TAG_pointer_type” that was added to the retained type list because of the explicit cast to (T*). This is the code that creates DW_TAG_subprogram: DIE *DwarfUnit::getOrCreateSubprogramDIE(const DISubprogram *SP, bool Minimal) { ... // DW_TAG_inlined_subroutine may refer
