VERSION: Unmolested gcc 1.34 bootstrapped with cc -pcc on first
build then normal bootstrap.

The following code:
main()
{
	int i;

	i = 0;

	if(1./4. == i)
		printf(" bug1 FAILED\n");
	else
		printf(" bug1 PASSED\n");
}
when compiled with gcc -O will produce the following assembler
instruction on line 13
	fmoveld #0,fp0
which the assembler will report as having an invalid operand.
Evidently a constant operand is not allowed, I checked that the FX
compiler did generate fmoveld, and it did, but it never generated it with
a constand operand.  I do not know how to constrain the machine description
entry to rule out a constand operand, but allow register and memory
references, which seems to be the ticket here.
