Maybe you can clear this up for me, regarding keeping the FPU stack
clean/the way I `expect it be' --

How/Why duz:
	asm("fldl %0" : : "f" (double_arg) );
become:
1:	/NO_APP
2:		fldl _double_arg
3:	/APP
4:		fldl %st
5:	/NO_APP
6:		fstp %st(0)
7:

Lines 4 and 6 don't leave st(0) with double_arg. gcc insists on putting
these extra instructions in the S file output. How do I stop this? What
is gcc doing ?

Thanks,
