not you may need to add calls to them to let the rewriter know where to
insert the loads/stores.

[LLVMdev] request for help writing a register allocator
I found the problem! My generated code is spilling correctly but is not
reloading at all. For example, if the original code has the equivalent of
this (where %1024 is a virtual reg):
%1024 = xxx
...
yyy = %1024
and I find no physical register for %1024, then I assign it to physical
register %edi and to a stackslot. That creates code like this:
%edi = xxx
store from %edi to the
