What version of LLVM are you using? I recently made some tablegen
changes to allow nodes to have multiple predicates. See r57565 for
an example of a change made possible by being able to have multiple
predicates on a node, and it sounds similar to what you describe.

[LLVMdev] Load/Store issues: tablegen/customization?
I've been running into two issues with load/store handling:
(1) is that tablegen doesn't seem to handle the two predicates that
get attached to my instructions. The first is the predicate in
TargetSelectionDAG.td, identifying a load node as, say, extloadi8. The
second is my identification of the load as having a particular address
space (need different instructions for different
