Subject: [Qemu-devel] [PATCH for-2.9 0/6] disas: Fix various coverity nits
Date: Fri,  3 Mar 2017 15:50:27 +0000	[thread overview]
Message-ID: <1488556233-31246-1-git-send-email-peter.maydell@linaro.org> (raw)

This patchset fixes all the coverity issues for disas/:
 * dead ?: code in hppa
 * a NULL pointer deref following an internal-error case
   in i386
 * unintended sign extension after shift of unsigned char
   in m68k, microblaze, cris, arm

The hppa, i386, and arm changes won't have a visible effect
as they're either "never happens" cases or the code doesn't
care. I think m68k, microblaze and cris are genuinely
bug fixes.

Disclaimer: generally compile tested only.

thanks
