Hi Juzhe,
I meant that “lens” is undefined, from looking around I guess that needs to be
vec_loop_lens *lens = &LOOP_VINFO_LENS (loop_vinfo);
for `bias` I meant
cond = gimple_build
s.

Thanks Tamar.
I am not sure whether I am not on the same page with you.
IMHO, ARM SVE will use the final mask = loop mask (generate by WHILE_ULT) &

Hi Juzhe,
I’m happy to take the hunks, just that I can’t test it and don’t know the

I still need to read up on it.
I tried adding that chunk in, but for the first bit `lens` seems undefined, and

I'll also need what to
