libgcc: Enable XF mode conversions to/from DFP modes only if supported
Some targets do not support XF mode (eg AArch64), so don't build the corresponding to/from DFP modes convertion routines if __LIBGCC_HAS_XF_MODE__ is not defined. 2022-03-31 Christophe Lyon <christophe.lyon@arm.com> libgcc/config/libbid/ * _dd_to_xf.c: Check __LIBGCC_HAS_XF_MODE__. * _sd_to_xf.c: Likewise. * _td_to_xf.c: Likewise. * _xf_to_dd.c: Likewise. * _xf_to_sd.c: Likewise. * _xf_to_td.c: Likewise.
