Title:
qemu/hw/i386/amd_iommu.c:188: possible bad shift ?
Status in QEMU:
Fix Released
Bug description:
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;
