llvm dev - May 2009 - [LLVMdev] "Processed value not in any map!" failures

When I build LLVM with ENABLE_EXPENSIVE_CHECKS=1, make check fails:

If it helps, at this point I->dump() gives:

0xa21e504: i64 = TargetConstant <1>

Thanks,

building with ENABLE_EXPENSIVE_CHECKS=1 turns on a bunch
of extra sanity checking in LegalizeTypes.  "make check" used to
pass all tests with this on.  I notice that the failing node is a target
constant.  These are a special case, and the code dealing with them
was tweaked a little while ago - probably that caused this.  I will
take a look.

Ciao,

Duncan.

Thanks for fixing this, Duncan!
