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
