<b>Subject:</b> [LLVMdev] Vector promotion broken for <2 x [i8|i16]><o:p></o:p></span></p>
</div>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Vector promotion which is new in LLVM 3.1 is broken for sub32 bit types. The problem is in the VectorLegalizer::PromoteVectorOp.<o:p></o:p></p>
<p class="MsoNormal">The function getTypeToPromoteTo will return a <2 x i32> for a <2 x i8>, <2 x i16> or <4 x i8>. The problem is that there are no vectors of size 1 defined for i32 or i16. The attached patch fixes these issues.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This can be reproduced by setting in any target:<o:p></o:p></p>
<p class="MsoNormal">setOperationAction(ISD::AND, MVT::i8, Promote);<o:p></o:p></p>
<p class="MsoNormal">setOperationAction(ISD::AND, MVT::v2i8, Promote);<o:p></o:p></p>
<p class="MsoNormal">setOperationAction(ISD::AND, MVT::i16, Promote);<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Let me know if this is good,<o:p></o:p></p>
