From 2c76a6f7f85365cefb5200b2b3408fd6bd421b3d Mon Sep 17 00:00:00 2001
From: Tobias Klauser <tklauser@distanz.ch>
Date: Wed, 12 May 2021 17:55:42 +0200
Subject: [PATCH] all: add //go:build lines to assembly files
Don't add them to files in vendor and cmd/vendor though. These will be
pulled in by updating the respective dependencies.
For #41184
