BUGS n code generated for target i386 compiling __bswapdi3, and for target x86-64 compiling __bswapsi2()
Hi @ll,
targetting i386, LLVM/clang generates wrong code for the following
functions:
unsigned long __bswapsi2 (unsigned long ul)
{
return (((ul) & 0xff000000ul) >> 3 * 8)
| (((ul) & 0x00ff0000ul) >> 8)
| (((ul) & 0x0000ff00ul) << 8)

[PATCH v10 0/2] s390: virtio: let arch validate VIRTIO features
Hi all,
The goal of the series is to give a chance to the architecture
to validate VIRTIO device features.
The tests are back to virtio_finalize_features.
No more argument for the architecture callback which only reports
if the architecture needs guest memory access restrictions for
VIRTIO.
I renamed the callback to arch_has_restricted_virtio_memory_access,
and the config option to
