[LLVMdev] MSVC compiling issue

That won't work either (that is, the assert fires). In debug mode the 
MSVC lib tries to test the ordering of the sequence. And it uses the 
yielded predicate for this (which in this particular case is a very bad 
idea).

Does that mean, that gcc actually only needs

bool operator()(const LiveRange&A, SlotIndex B) ?

According to C++(2003) 25.0.0.8 the answer is "yes", however that 
section talks about BinaryPredicate and not Compare. The standard is 
rather unclear at this point and I'm going over to comp.std.c++ to ask.
