Re: [fpu] FPU compilation problem

[dmackesy@site.uottawa.ca]

Substituting the following code in place of line 315 seems to work fine:

assign ok_shift_f2i = f2i_shft > 8'd56;
assign shift_amt = ok_shift_f2i ? 6'd56 : f2i_shft[5:0];
assign exp_f2i_1 = {{8{fract_in[47]}}, fract_in } << shift_amt;

Obviously you have to create two new wires as well (ok_shift and 
shift_amt)
