has hard float, when you compile the mips32 code you have to make sure that it knows to compile any mips32 routines as hard float. I need to clean up the way mips16 hard float is specified but I need to first think through all the details. Mips16 always has a form of soft float, the difference being whether the underlying hardware has floating point. So it's not really necessary to pass the -soft-float to llvm since soft-float is always true for mips16 by virtue of the fact that it will not register floating point registers. By using this fact, I can simplify the way this is all handled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189690 91177308-0d34-0410-b5e6-96231b3b80d8
