[Qemu-trivial] [PULL 04/14] target-ppc: Fix compiler warning

From: Michael Tokarev
Subject: [Qemu-trivial] [PULL 04/14] target-ppc: Fix compiler warning
Date: Tue, 24 Jun 2014 20:09:10 +0400

From: Stefan Weil <address@hidden>

gcc reports a warning which is usually wrong:

target-ppc/dfp_helper.c: In function ‘dfp_get_digit’:
target-ppc/dfp_helper.c:417:1: warning:
 control reaches end of non-void function [-Wreturn-type]

The compiler shows the warning if assert is not marked with the noreturn
attribute or if the code is compiled with -DNDEBUG.

Using g_assert_not_reached better documents the intention and does not
have these problems.
