[Stefan Liebler]

The new hwcap values indicate support for arch14 architecture.

I hope it's deliberate not to update HWCAP_IMPORTANT.

Should we add an arch14 glibc-hwcaps subdirectory, or can that wait?

Thanks,
Florian

Hi Florian,

I won't update HWCAP_IMPORTANT.

Even if in future the libraries are not loaded anymore in a subdirectory
with AT_PLATFORM string, I want to keep it in sync with the glibc-hwcaps
subdirectory mechanism. As soon as I know the name, I will post a
further patch. This will also introduce a further libmarkermod5.so in
order to extend tst-glibc-hwcaps.

Thanks,
Stefan
