I have been trying to compile some Llvm code that I generate, and I am running into a problem assembling my ll code. Here is a snippet of the code I am trying to compile:<br> %loc0 = alloca i32<br> call void @llvm.dbg.declare( { }* bitcast(i32* %loc0 to { }*), { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable1 to { }*) )<br>
<br>I get an error from the second line of code:<br> Invalid reference to global<br><br>Just to try to get the code to compile, I replaced the reference to %loc0 with null:<br> %loc0 = alloca i32<br> call void @llvm.dbg.declare( { }* bitcast(i32* null to { }*), { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable1 to { }*) )<br>
<br>This code compiles fine, but obviously will not give the end result I want.<br><br>My current solution is to introduce a temporary variable like this:<br> %loc0 = alloca i32<br> %loc0_void = bitcast i32* %loc0 to { }*<br>
call void @llvm.dbg.declare( { }* %loc0_void, { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable1 to { }*) )<br><br>I would prefer to make the first code snippet work (to avoid adding temporary variables and cluttering up the ll code). But my workaround is alright for now.<br>
<br>I am wondering why my first code snippet doesn't compile properly. Am I doing something incorrect? Or is this possibly and LLVM bug of some kind?<br><br>Thanks a lot,<br>Dave Cope<br><br>
