The last sentence is not completely correct, since the feature is available
on pre-Power9 cpus too. The first sentence could be worded a little better
too. How about:
GCC version 14 onwards supports the __builtin_set_fpscr_rn built-in,
which now returns the FPSCR fields in a double. This feature is
available when the __SET_FPSCR_RN_RETURNS_FPSCR__ macro is defined.
