Teach APFloat how to create both QNaNs and SNaNs and with arbitrary-width payloads. APFloat's internal folding routines always make QNaNs now, instead of sometimes making QNaNs and sometimes SNaNs depending on the type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97364 91177308-0d34-0410-b5e6-96231b3b80d8

Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8

Do not use host floating point types when emitting ASCII IR; loading and storing these can change the bits of NaNs on some hosts. Remove or add warnings at a few other places using host floating point; this is a bad thing to do in general. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62712 91177308-0d34-0410-b5e6-96231b3b80d8

Make special cases (0 inf nan) work for frem. Besides APFloat, this involved removing code from two places that thought they knew the result of frem(0., x) but were wrong. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62645 91177308-0d34-0410-b5e6-96231b3b80d8
