Could you re-title this patch into something like "Support const
vector expansion with xxx pattern",

I didn't take a close review yet, (and I suspect I can't find time
before I start my vacation :P), but I am thinking we may adding
selftests for expand_const_vector in *future*, again, not blocker for

I'll take this one. Go enjoy your vacatio

Hi Juzhe,
seems a nice improvement, looks good to me. While reading I was wondering
if vzext could help synthesize some (zero-based) patterns as well
(e.g. 0 3 0 3...).
However the sequences
Hi Juzhe,
seems a nice improvement, looks good to me. While reading I was wondering
if vzext could help synthesize some (zero-based) patterns as well
(e.g. 0 3 0 3...).
However the sequences I could come up with were not shorter than what we
