<br>
I would like to disable vectorization on the XCore target by default.<br>
<br>
I assume I need to push_back -fno-vectorize in clang/lib/driver/Tools.cpp for Triple::xcore.<br>
<br>
Should I also disable the pass in llvm explicitly?<br>
I tried setting getNumberOfRegisters in XCoreTTI::TargetTransformInfo viz:<br>
<br>
unsigned getNumberOfRegisters(bool Vector) const {<br>
if (Vector) {<br>
return 0;<br>
}<br>
return 12;<br>
}<br>
<br>
But this made no difference (I need to double check).<br>
<br>
What is the correct way to disable vectorization passes?<br>
<br>
