reg+reg isn't valid for TFmode (because reg+reg+offset isn't valid for the
second half). My guess would be that in rs6000_legitimize_address
else if (GET_CODE (x) == PLUS
&& GET_CODE (XEXP (x, 0)) == REG
&& GET_CODE (XEXP (x, 1)) != CONST_INT
&& GET_MODE_NUNITS (mode) == 1
&& ((TARGET_HARD_FLOAT && TARGET_FPRS)
|| TARGET_POWERPC64
|| (((mode != DImode && mode != DFmode && mode != DDmode)
|| TARGET_E500_DOUBLE)
&& mode != TFmode && mode != TDmode))
&& (TARGET_POWERPC64 || mode != DImode)
&& mode != TImode)
should disallow TFmode like it disallows TImode.
