Hello All,

I have problems with ctfconvert with build sources of xen-4.2 on illumos based platform:

could you please let me know - what the reason to have a variable in structure 'struct hvm_hw_cpu_xsave' with zero size:
struct { char x[0]; } ymm;    /* YMM */

Best regards,

The structure is variable length depending on whether the VM has enabled AVX support.

It is rather unfortunate that we have non-complient C used to specify the ABI.
