From 38de91b028639ef5f4a4c8874b3ee23503fd2f3a Mon Sep 17 00:00:00 2001 From: Fabricio Voznika Date: Thu, 30 May 2019 12:01:41 -0700 Subject: Add build guard to files using go:linkname Funcion signatures are not validated during compilation. Since they are not exported, they can change at any time. The guard ensures that they are verified at least on every version upgrade.
