Subject: openbios: do not error-out array-bounds warning
From: Michael Tokarev <mjt@tls.msk.ru>
Date: Fri, 02 Sep 2022 18:35:30 +0300
gcc-12.2 produces an apparently wrong warning for this file:
roms/openbios/arch/ppc/qemu/init.c:400:10: error: \
array subscript 0 is outside array bounds of ‘uint32_t[0]’ {aka ‘unsigned int[]’} \
[-Werror=array-bounds]
400 | *dsi = 0x48002002;
| =====^===========
Turn this particular -Werror back into warning. Gcc is apparently wrong here.
