Hi all, -soft-float can not be rightly use by llc. All float function operation will call soft float, but not hard. My mips device cannot support half float type, so I hack the llvm, and add soft half float and add -soft-float option. I add the function define for __gnu_f2h_ieee() and __gnu_h2f_ieee (), and it can call the soft half float. However, all the others function about float also call the soft float, how I do make only __gnu_f2h_ieee() use soft float, other use hard float??? Thank you all !!
