Yeah the SIGILL trapping is a bit nasty, but that is only used if no implementation of getauxval() exists. So perhaps the cleanest way to approach this is to provide a dummy implementation of getauxval() which only supports AT_HWCAP, and returns the correct hwcap mask for what the CPU id registers report in terms for ISA support for crypto extensions. I can code that up if you want. -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
