Hi, > You need to call di.createCompileUnit() once for your translation unit in the beginning. You don't need to keep track of CU yourself. DIBuilder will take care of it. After words, you can call di.createBasicType(..) and it will work. Actually it doesn't. But if I call di.createCompileUnit(file, dir, producer, ...) with file or dir different from that of CU already in the file,

I get the filename and directory from DISubprogram from reading llvm.dbg.sp and use that to DIBuiler::.createCompileUnit. This leads to "duplicate symbol" error from llc. >>> You need to call di.createCompileUnit() once for your translation unit in the beginning. You don't need to keep track of CU yourself.

Hi, I am wondering if someone can guide me in adding metadata to IR which already contains some metadata. I am trying to add dbg.declare inst for a local variable I added to a function. I used the DIBuilder to build a DIVariable. When I try to compile llc fails with following message. llc: MCAsmStreamer.cpp:273: virtual void<unnamed>::MCAsmStreamer::EmitLabel(llvm::MCSymbol*): Assertion
