Chris Lattner	44298d184a	Teach codegen to lower llvm.powi to an efficient (but not optimal) ... multiply sequence when the power is a constant integer. Before, our codegen for std::pow(.., int) always turned into a libcall, which was really inefficient. This should also make many gfortran programs happier I'd imagine. llvm-svn: 92388	2010-01-01 03:32:16 +00:00
