[Xen-devel] [PATCH for-4.13 0/6] xen/arm: Add support to build with clang

Posted by Julien Grall 4 years, 6 months ago

Hi all,

After this series, I am able to build Xen on Arm64 with clang 7.0. There
are still some issues when building Xen on Arm32 and also using lld.

Cross-compilation is left outside for now, but this is still a good start
for clang (and armclang).

Cheers,

Julien Grall (6):
  xen/arm: fix get_cpu_info() when built with clang
  xen/arm64: bitops: Match the register size with the value size in flsl
  xen/arm: cpuerrata: Match register size with value size in

  xen/arm: cpufeature: Match register size with value size in
    cpus_have_const_cap
  xen/arm: mm: Mark check_memory_layout_alignment_constraints as unused
  xen/arm: traps: Mark check_stack_alignment_constraints as unused
