Subject: optabs: Variable index vec_set
Date: Mon, 31 Oct 2022 16:42:56 +0100	[thread overview]
Message-ID: <546be11b-5bb6-e312-e309-291787d25018@linux.ibm.com> (raw)

Hi,

I'm looking into vec_set with variable index on s390.  Uros posted a
patch [1] that did not make it upstream in Nov 2020.  It changed the
mode of the index operand to whatever the target supports in
can_vec_set_var_idx_p.  I missed it back then but we indeed do not make
proper use of vec_set with an index register.

With the patch my local changes to make better use of vec_set work
nicely even though I haven't done a full bootstrap yet.  Were there
other issues with the patch or can it still be applied?

Regards
 Robin
