I want to insert some functions into the llvm bitcode ir files.

So I use IRBuilder and CreateCall().

But it how error : inlinable function call in a function with debug info must have a !dbg location.

I don't know what DebugLoc should I give the new CallInst to setDebugLoc.

I Create this CallInst , so this CallInst doesn't hava so-called "DebugLoc" mapping to the source code , right ?

And also I want the compiler can do some inline optimization to my program.

So I have to give this CallInst a DebugLoc....

What would happen if the DebugLoc of an Instruction is wrong ?

would there be any error?
