Hi Alexander,
An evaluation needs to be made of the benefit of a new multilib for Armv8-R
(instead of reusing an existing multilib) compared to the extra maintenance and
build time.
Best regards,
Thomas

Hi Thomas
Don't you know by the way why ARMv8-R is not listed in t-rmprofile multilib ?

That or just use -mfpu=auto (as in -mcpu=cortex-r52 -mfpu=auto
-mfloat-abi=(softfp|hard)).

So in order to set dp+Neon for armv8-r I should to use switch
"neon-fp-armv8". Not an fpv5-d16. Right ?

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 ?
