Hi Carlos

Sorry… forgot to answer about this.

In the static case, processing of the auxiliary vector occurs in generic_start_main (). However, the earliest I can add my initialization function in the arch-specific code is at powerpc’s __libc_start_main () in sysdeps/unix/sysv/linux/powerpc/libc-start.c. That runs before the auxv initialization, therefore I need to add handling of AT_HWCAP, AT_HWCAP2 and AT_PLATFORM at that point.

Regards,
