From e887688b8e39a2abad0707b080f3282306c1c8bf Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Fri, 7 Sep 2012 12:24:32 +0200 Subject: [PATCH] tcg/optimize: fix if/else/break coding style optimizer.c contains some cases were the break is appearing in both the if and the else parts. Fix that by moving it to the outer part. Also move some common code there.
