llvm dev - Dec 2012 - [LLVMdev] Value not in slotcalculator! error

Hello,

This is my first post to llvmdev (reading for about a month) so I apologize if
I'm not following protocol.

I'm writing a Common Lisp compiler using LLVM with the C++ API and I'm
experiencing a problem that I have not been able to solve by myself.

I'm getting a "Value not in slotcalculator" when I write out
bitcode for a module that I generated.

It happens the second time that I compile the same source code - the first time
everything works fine and the functions all verify fine.

Here's what I know: when I dump the value that seems to be responsible for
the error:

input>> call V->dump()
output>> declare void @_Unwind_Resume(i8*)

Now the funny thing is I don't call this function, it gets inserted into my
code when I generate a "resume" instruction using
IRBuilder::CreateResume for exception handling.  I've tried adding a
declaration for _UnwindResume myself but that doesn't do anything.

Any help would be appreciated.

Best,

Christian Schafmeister

try running under valgrind.

Do they verify fine just before you write the bitcode?  Both the first and the
second time?

This looks like the kind of change the code generators might make.  Did you
run the code generators?

Ciao, Duncan.
