</span>It makes the LLVM IR simpler by removing the "lifetime" intrinsic that is added by the "-inline" pass.<br>
Other than that it is not needed.<br>
<br>
Anyway, once I use the "always_inline" attribute you suggested, there is no need for "-inline" nor "-soa" passes.<br>

I just needed to keep the static, so clang can get rid of the inlined function once it inline it.<br></blockquote><div><br></div><div>Hmm, that shouldn't be necessary - in C++ an inline function, once inlined into all the call sites, should be removed/omitted entirely by the optimizers, even at -O0. Oh, so long as the function is marked inline - so inline or static would be needed (in addition to the always_inline attribute, in either case), not both. I usually use inline, but I'm not especially wedded to it or anything.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
