Hi, I would like to extend DebugInfo library for the purpose of using it in AddressSanitizer/ThreadSanitizer run-time libraries. Current interface is: class DILineInfo { const char *FileName; uint32_t Line; uint32_t Column; ... }; class DIContext { ... virtual DILineInfo getLineInfoForAddress(uint64_t address) = 0; }; First, I would like to get function name associated with the

...lar/value/addr intrinsic, then the DILocation attached to the intrinsic indirectly points there: > > DIScope *Scope = DILocation(dbg_intrinsic.getDebugLoc()).getScope(); > while (!isa<DISubprogram>(Scope)) > Scope = Scope->getScope(); > auto *origFunction = cast<DIFunction>(Scope); This works, thank you! (I had to slightly modify the code FWIW: DILocation *DIL = dbg_intrinsic.getDebugLoc(); if (DIL) { DIScope *Scope = DIL->getScope(); while (Scope && !isa<DISubprogram>(Scope)) Scope = Scope->getScope().resolve();...

...variable, without any actual function at all. To build corresponding debug info, I must: 6. Build a llvm::DIArray, using llvm::getOrCreateArray, from the results of 4. 7. Build a llvm::DIComposite type for the function, using llvm::createSubroutineType, from the result of 6. 8. Build a llvm::DIFunction using llvm::createFunction, from the result of 7. Here, I need the formal values, with names, first, before building the function type. This appears to imply that, in debug info, the formal names are also part of the function type, which thus cannot be reused for a different function with diff...

(I think I've asked a similar question off-list a couple of times, but never got an answer) Hi folks, For [K]MSAN we need to figure out which inlined function a local var originally belonged to in the source file. E.g. when a local buffer %buf is declared in @bar(), but @bar() is inlined into @foo(), then there's a local %buf.i in @foo(), but we need to determine that the local came from
