Subject: [Qemu-devel] [PATCH 0/2] target-i386: Fix undefined behavior on bit shifts
Date: Tue, 29 Sep 2015 17:34:21 -0300 [thread overview]
Message-ID: <1443558863-26132-1-git-send-email-ehabkost@redhat.com> (raw)
This fixes two errors detected by clang:
target-i386/cpu.c:1494:15: runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
target-i386/translate.c:2423:26: runtime error: left shift of negative value -8
Eduardo Habkost (2):
target-i386: Use 1UL for bit shift
target-i386: Don't left shift negative constant
target-i386/cpu.c | 2 +-
target-i386/translate.c | 2 +-
