ICI->getPredicate() == ICmpInst::ICMP_EQ.

See the doxygen for CmpInst: http://llvm.org/doxygen/classllvm_1_1CmpInst.html and ICmpInst: http://llvm.org/doxygen/classllvm_1_1ICmpInst.html . (Note that ICI->isEquality() returns true for both 'eq' and 'ne'.)

The “eq” part means “equality”. That’s how you know which kind of comparison you’re dealing with. You should read about the icmp instruction.
