Hi all,
This is a minor patch that fixes the entry for the fp16fml feature in
GCC's aarch64-option-extensions.def.
As can be seen in the Linux sources here
https://github.com/torvalds/linux/blob/master/arch/arm64/kernel/cpuinf
o.c#L69
the correct string is "asimdfhm", not "asimdfml".
Cross-compiled and tested on aarch64-none-linux-gnu.
Is this ok for trunk?
Also, I don't have commit rights, so could someone commit it on my behalf?
James approved it offline so I've committed it on Stam's behalf as
r276097 with a slightly adjusted ChangeLog:
2019-09-24 Stamatis Markianos-Wright <stam.markianos-wri...@arm.com>
* config/aarch64/aarch64-option-extensions.def (fp16fml):
Update hwcap string for fp16fml.
Thanks,
Kyrill
