</div>It might not block the compilation process, but it might break the<br>
linking process (build attributes, libraries), or change code<br>
generation, with regards to vectorization and optimizations. I agree<br>
this is not critical, but it's the kind of bug that is hard to find<br>
(as opposed to a compilation error), and the kind of warnings that<br>
people tend not to look at.<br>
<br>
I have no more arguments against the removal, and I don't feel too bad<br>
about it, but was just raising the issue. If people think it's for the<br>
best, I'll go with it.<br>

</div>Hum... ok, I had no idea, and from their docs, it's not clear also. In<br>
that case, fine by me.<br>
<br>
Thanks for threading this awkward minefield! I think Tim and others<br>
more involved in the AArch64 port should have a final look, but from<br>
what you discussed, I have no more objections.<br>
<br>
