(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

Hi All, I want to change debug information of an llvm instruction so that the modified debug info is subsequently passed to executable binary. So if I use "addr2line" utility on the binary, it will return my modified debug information. I've tried to change by using the following code snippet: MDNode *N = Inst->getMetadata("dbg"); DebugLoc Loc =

However, if Scope is a LexicalBlock, getDirectory() returns the filename (conv.c) iso. the directory. The associated .ll does hav...

...ich lacks the is_stmt flag. The relevant code is: unsigned Flags = 0; PrevInstLoc = DL; if (DL == PrologEndLoc) { Flags |= DWARF2_FLAG_PROLOGUE_END; PrologEndLoc = DebugLoc(); } if (PrologEndLoc.isUnknown()) Flags |= DWARF2_FLAG_IS_STMT; if (!DL.isUnknown()) { const MDNode *Scope = DL.getScope(Asm->MF->getFunction()->getContext()); recordSourceLine(DL.getLine(), DL.getCol(), Scope, Flags); It's easy to change this code to apply is_stmt for every line table entry but I think that this is the wrong approach. The real question is, why do we have an inconsistency where some...
