Hi Alexander,
As mentioned in [1], Arm Cortex-R52 can have either single precision or double
precision + Neon. This is reflected in GCC 8 by -mcpu=cortex-r52 defaulting to
the latter (double precision + Neon) and -mcpu=cortex-r52+nofp.dp giving you the
former (single precision).

Hi,
As I understand from this
https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html current master
branch doesn't have support of double-precision FPv5 floating-point
instructions for ARMv8-R (Cortex-r52).
If yes, are there any chances to see them in GCC 8 ?
