From 2208d64998c5f867ccee7eeee298971685bf822d Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Wed, 17 Feb 2016 23:48:25 -0700 Subject: qapi-visit: Use common idiom in gen_visit_fields_decl() We have several instances of methods that do an early exit if output is not needed, then log that output is being generated, and finally produce the output; see qapi-types.py:gen_object() and qapi-visit.py:gen_visit_implicit_struct(). The odd man out was gen_visit_fields_decl(); rearrange it to be more like the others. No semantic change or difference to generated code.
