From 56d92b003a223585980df5403ee9e3a55de90adf Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Wed, 16 Sep 2015 13:06:21 +0200 Subject: [PATCH] qapi-commands: De-duplicate output marshaling functions gen_marshal_output() uses its parameter name only for name of the generated function. Name it after the type being marshaled instead of its caller, and drop duplicates. Saves 7 copies of qmp_marshal_output_int() in qemu-ga, and one copy of qmp_marshal_output_str() in qemu-system-*.
