I didn't mention gcc.. I agree they shouldn't be used in the wild, but<br>
they are..<br>
<br>
Why not leave the built-in support and under the hood just map that to<br>
something more portable? This is a pretty low cost (zero?) maintenance<br>
burden...<br>
<br>
Intentionally breaking stuff without at least giving any warning or<br>
marking as deprecated in a major release 1st.. Is this an exception<br>
because __built-ins are grey area support?<br><br></blockquote><div><br></div><div>What Reid is saying has been our policy from the beginning, there's even a script in the repository (that I sadly haven't updated in years) that helps handle the transition between builtins and the *mmintrin.h headers.</div></div></div></div></blockquote><div><br></div></span>I agree that we don't need to support undocumented builtins.</div><div><br></div><div>John.</div></div><br></blockquote></div></div><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">_______________________________________________<br>
