-msoft-float -m64 x86 machine, gcc is not referring to software floating point librar

[achaleus]

Dear edaboard,
I have a third party software floating point library which was compiled using 64 bit machine (-m64). I am trying to infer this floating point library using gcc flag -msoft-float.

If I am using gcc -msoft-float -m32 flag for c = a+b, where c,a,b are float values,gcc infers assembly __addsf3 which is a software fp library. If I am trying to use gcc -msoft-float -m64 flag for the same c = a+b, gcc infers hardware floating point addss.
Any suggestion on how to infer software floating point library using -m64 option are greatly appreciated

-one is to link your thirdparty lib as -lthirdpartlibname.

And this seems to be supported only in some versions of gcc.
