From 24f4d3d3aeabf83445839099d6d66cbb3089c37a Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 10 Jan 2018 20:25:53 +0000 Subject: tracetool: report error on foo() instead of foo(void) C functions with no arguments must be declared foo(void) instead of foo(). The tracetool argument list parser has never accepted an empty argument list. This patch adds a clear error message for this error case.
