Hi folks, While building openmpi.4.0.0(Optimized debug build), using trunk clang we encountered a crash(assertion failure). Initially assertion seems trivial: [...] void llvm::DwarfExpression::addFragmentOffset(const llvm::DIExpression*): Assertion `FragmentOffset >= OffsetInBits && "overlapping or duplicate fragments"' failed. [...] But, narrowing to RC. We discovered "-O3 -enable-partial-inlining" pass which is doing some DebugInfo manipulation, later triggering this.

Hello, I'm using DIBuilder to create debugging information, I'm not clear about two things: [1] Could you help explain the meaning and the difference between"alignment" and "offset" of a type ? e.g class Actor{ int age; const char* name; } Besides, I found the denotation of createMemberType and createStructType both have "Member

Are there any utility classes, similar to IRBuilder, for creating source level debugging info? -- Talin

I don't think so. Contribution welcome! :-) LLVM debugging support isn't anywhere near where it needs to be.

...Then when parsing a METADATA_COMPOSITE_TYPE, if we are importing a module I change the calls to buildODRType and GET_OR_DISTINCT to instead create a type declaration: - pass in flags Flags|DINode::FlagFwdDecl - pass in nullptr for BaseType, Elements, VtableHolder, TemplateParams - pass in 0 for OffsetInBits Note that buildODRType will not mutate any existing DICompisiteType for that identifier found in the DITypeMap to a type declaration (FlagFwdDecl) though. This is good since we are sharing the DITypeMap with the original (destination) module, and we don't want to change any type definitions o...

Hi list, Is there a standards based reason why the DIFlags enum is set to uint32_t[1]? I am sure my DWARF-std-reading-fu is not up to snuff and so I cannot seem to find it. The reason I ask is that we are running out of space for our own DIFlags and would like to nail this down before deciding on an approach. Thanks! Sohail [1] The code in question:
