Sample source
In the attached source, compiled with -O2 -g on x86-64 Linux, the local
variable "op" is live for at least several instructions, but the debug info
shows no location for it. We ought to be able to keep track of that.
The local "delta" is live for one instruction, but also has no location in
the debug info. That one seems a little iffier but seemed worth mentioning.
I won't have time to look at this for a while, so I figured I'd post the
bug in case somebody else got inspired. Source and .s attached.</pre>
