From c2c7065e1752a3be1b437d1ea359cde35d28ee3b Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Sat, 14 Sep 2019 17:34:58 +0200 Subject: [PATCH] qapi: Reject blank 'if' conditions in addition to empty ones "'if': 'COND'" generates "#if COND". We reject empty COND because it won't compile. Blank COND won't compile any better, so reject that, too.
