haveSameSpecialState()

static bool haveSameSpecialState ( const Instruction *  I1, const Instruction *  I2, bool  IgnoreAlignment = false  )

static

Return true if both instructions have the same special state.

This must be kept in sync with FunctionComparator::cmpOperations in lib/Transforms/IPO/MergeFunctions.cpp.
