Here is the program (test.c) For 32-bit, -msoft-float is a distinct ABI from -mhard-float, and requires its own copies of libgcc, libc, etc.; you can't just build and run a soft-float program on a hard-float system without building all those separate libraries and arranging for the program to find them at link time and run time. For 64-bit, -msoft-float is not supported, and hard-float is always available. (__float128 might use software or hardware floating point - software before POWER9, hardware with POWER9 - but that's controlled by other options.)
