Comment at: lib/Basic/Targets/Mips.cpp:141
+                      Twine(32 / (FPMode == FP64 || IsSingleFloat ? 1 : 2)));
 
   if (IsMips16)
----------------
What do you think about this variant of the code? It's longer, but imho looks more clear.
```
switch (FPMode) {
case FPXX:
  Builder.defineMacro("__mips_fpr", Twine(0));
  break;
case FP32:
  Builder.defineMacro("__mips_fpr", Twine(32));
  break;
case FP64:
  Builder.defineMacro("__mips_fpr", Twine(64));
  break;
}

if (FPMode == FP64 || IsSingleFloat)
  Builder.defineMacro("_MIPS_FPSET", Twine(32));
else
  Builder.defineMacro("_MIPS_FPSET", Twine(16));
```
