Bug #4398
openAspectator and C back-end should support GCC vector type
0%
Description
There are some issues related with unsupported GCC vector type on kvm drivers. They happen just for 3 drivers, that use "sse128_t"http://lxr.free-electrons.com/source/arch/x86/include/asm/kvm_emulate.h#L212 vector type.
Previously these drivers have led to segfault (#4390) when using specific aspect files, and have led to a failure of C-backend for any aspect file. At the moment Aspectator fails when it encounters it. Vector types should be supported in both Aspectator and C-backend.

It is as relevant today as it's ever been

It seems that to support this normally we need to do many things because of GCC operates with specific types internally rather than with, say, integers with corresponding attributes.
Suddenly, to avoid corresponding errors from CIF when dealing with source code of the Linux kernel it is enough to add the following command-line option:
-Dvector_size(x)=
This suppresses the only vector type that is used in the Linux kernel. Hopefully, the rest code does not use specific vector operations. Corresponding data is passed to inline assembler that is ignored.
