Hi,
After supporting all vcond/vcondu patterns in AArch64 backend, now we can vectorize VEC_COND_EXPR with different type in comparison operands and value operands on AArch64.  GCC uses vect_cond_mixed to control such test cases, for now, there are below cases affected by it:

pr61194.c
    This was failed for all targets, but was just fixed by my previous tree ifcvt patch.
slp-cond-2-big-array.c
slp-cond-2.c
vect-cond-10.c
vect-cond-8.c
vect-cond-9.c

They will start passing after this patch.

Test on AArch64.  Is it OK?

Thanks,
bin
