On the other hand both clang and GCC *do* set an alarmingly similar looking macro - "__SOFTFP__" (no middle underscore) - when compiling for soft-float.
Since we need to build compiler-rt libraries for a couple of our soft-float targets at Wind River, we want to make sure we're building them in the "right" way. Currently we do *not* define __SOFT_FP__ for soft-float targe...
