  6. In our context, some construct has decided that we don't support
  7. XF mode (which is not true for the architecture, in general, as
  8. this patch supports, but is sufficient for our strange environment).
  10. Backport of commit 43ccb7e445329dd9557b42e7289a87a8071ab0f7.
  12. [PATCH] libgcc: Enable XF mode conversions to/from DFP modes only if
  13.  supported
  15. Some targets do not support XF mode (eg AArch64), so don't build the
  16. corresponding to/from DFP modes convertion routines if
  17. __LIBGCC_HAS_XF_MODE__ is not defined.
