Flat source listing including library calls

I would like to use floats for a particular routine in my project. However I do not have enough space to include the float library and leave it there statically. To effectively have a larger code space, currently I bring in code segments from an external ROM and execute them, making extensive use of the USER SEGMENTS.

Is there a way to relocate individual routines in the float library as in the SEGMENTS directive?

Alternately is there a way to get an assembler listing which does not include calls to the float library from code similar to below using directives like
#pragma listinclude
#pragma src
?

I have the full verstion of uVision 3 and have looked for the floating point library source but feel stymied. I have even tried to EXTRACT some of the functions but was not sure how to go about it.

Thanks,
David

float a;
float b;
signed long c;

void main(void){
}

void divide(void){
a = a / b;
} void cast(void){
a = (float) c;
}
