On cores without fpcvt support, we cannot promote int_to_fp i1 operations, because there is nothing to promote them to. The most straightforward implementation of this uses a select to choose between the two possible resulting floating-point values (and that's what is done here). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203015 91177308-0d34-0410-b5e6-96231b3b80d8
