From 93b564c444edc41901d0f7e922833eeb751f8249 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Sun, 11 Feb 2018 10:35:44 +0100 Subject: qapi: Reduce use of global variables in generators some MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In preparation of the next commit, which will turn the generators into modules. These global variables will become local to main() then.
