Personally, I like the idea that LD_HWCAP_MASK can affect ifunc
resolvers. Â It gives users a single method to turn off some hardware
capability across all libraries. Â I can see where finer grain control
might also be useful but I think that in general we are going to have
situations where a particular hardware capability is just not working
the way it should and so we want to turn off its use everywhere in an
executable.

OK, I have sent this off in a seperate thread.
