Could we look at the âVersion needsâ section (.gnu.version_r) and perhaps
use a special symbol version for getrandom?


Such a special symbol would mark getrandom as needing early resolution?

We already scan .gnu.version_r, so we can quickly detect special casesat very little extra cost. It's somewhat ugly because it's not ageneric mechanism like IFUNC (but then, the IFUNC experience suggestsit's better to gather internal users first before providing a genericinterface).
