-msoft-float
Generate output containing library calls for floating point. Warning: there
is no GNU floating-point library for SPARC. Normally the facilities of the
machine's usual C compiler are used, but this cannot be done directly in
cross-compilation. You must make your own arrangements to provide suitable
library functions for cross-compilation.
-msoft-float changes the calling convention in the output file; therefore,
it is only useful if you compile all of a program with this option.
