Yep, it's once again variable and it's type using different scopes. Is there any strong reason why you set scope for global DIDerivedType? ________________________________________ От: Carlo Kok <ck at remobjects.com> Отправлено: 21 марта 2018 г. 18:22 Кому: Evgeny Leviant; llvm-dev at lists.llvm.org Тема: Re: [llvm-dev] lld/lto/win32 crash on DIE code Thanks!

This isn't a realistic/viable implementation, just a hacked up "can I make it produce the right output" kind of thing, but while I hammer out a few more details (like fixing MC to allow multiple sections with the same name but different comdat groups) I figured I'd throw it out there to have a bit of a chat about it. I've tested simple cases of a single type and they seem to

I'm looking for a way to efficiently traverse the Metadata structure in reverse, or otherwise find DITypes that refer to another DIType. As an example, say I have a DICompositeType describing a struct. Now I want to find other DITypes containing this type, e.g. a DIDerivedType describing its pointer type, or another struct containing this struct as one of its fields. Is this possible in LLVM today? Would it be unreasonable to save Metadata to Metadata uses, like what is done for Value to Value uses? Any help would be greatly appreciated, Henrik -------------- next part...

...3.png] I've already found at least one bug in my compiler's frontend using this tool :) Oh, and before I forget, I need three small changes to DebugInfo.h: - DebugInfoFinder's 'module' parameter should be const. - isArtificial should return a bool, not an unsigned. - DIDerivedType should have an method that allows access to the 'name' attribute of the DIE.
