Hi @efriedma,

I remove the IsCastFromFloat flag and store the SDNode before soften in MakeLibCallOptions struct. So that the shouldExtendTypeInLibCall could get the original type directly and get rid of the complicate IsCastFromFloat setting method. I try to illustrate most of the single soft-float functions in rv64i-single-softfloat.ll. Please kindly remind me if I still missing something, thanks.
