Hard float for mips16 means essentially to compile as soft float but to use a runtime library for soft float that is written with native mips32 floating point instructions (those runtime routines run in mips32 hard float mode). The patch reviewed by Reed Kotler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195123 91177308-0d34-0410-b5e6-96231b3b80d8
