qemu/hw/i386/amd_iommu.c:188: possible bad shift ?
qemu/hw/i386/amd_iommu.c:188]: (error) Shifting 32-bit value by 64 bits is undefined behaviour
Source code is
uint64_t mask = ((1 << length) - 1) << bitpos;
Maybe better code
uint64_t mask = ((1ULL << length) - 1) << bitpos;
Thanks for reporting this bug! Looks like this has already been fixed by this commit here:
http://git.qemu.org/?p=qemu.git;a=commitdiff;h=1d5b128cbeeab638f772e
Released with v2.8
