Subject: [PATCH] Fix constant folding for one lane vectors (PR15611)<br>
<br>
Hi,<br>
<br>
The attached patch fixes constant folding for one lane vectors,<br>
which is the root cause for PR15611. The faulty code path is<br>
taken by scalarizing vector code during type legalization.<br>
<br>
The constant folding code will currently return a scalar when<br>
taking one lane input vectors, which can cause an assertion failure<br>
later.<br>
<br>
The changed code was wrong because if the size of the output vector<br>
is 1, we can still be in the case where we need to return a one lane<br>
vector.<br>
<br>
Please review!<br>
<br>
Thanks,<br>
Silviu<o:p></o:p></p>
