[Qemu-devel] [PATCH v2] spapr: Fix compiler warnings for some versions of gcc

[Stefan Weil]

i686-w64-mingw32-gcc (GCC) 4.6.3 from Debian wheezy reports these warnings:

hw/ppc/spapr_hcall.c:188:1: warning:
 control reaches end of non-void function [-Wreturn-type]

hw/ppc/spapr_pci.c:454:1: warning:
 control reaches end of non-void function [-Wreturn-type]

Both warnings are fixed by using g_assert_not_reached instead of assert.
A second line with assert(0) in spapr_pci.c which did not raise a compiler
warning was modified, too, because g_assert_not_reached documents the
purpose of that statement and is not removed in release builds.

This patch is an improved version which replaces
http://patchwork.ozlabs.org/patch/253939/ and
http://patchwork.ozlabs.org/patch/253938/.

Patch http://patchwork.ozlabs.org/patch/253937/ of my
previous series is still applicable. Please consider
applying it to the ppc queue.

I suggest replacing assert(0) by g_assert_not_reached()
in the rest of QEMU's code, too. If there is consensus,
I'll send a patch which does this.

Replacing assert by g_assert would also make sense with a
few exceptions in time critical code (TCG, TCI).

Regards
Stefan W.
