<div dir="ltr">Were you trying to use a Debug build to build LLVM? Yes, that would be very slow.<br><br>If you mean you were using a release build of LLVM to build a Debug build of LLVM - yeah, that's generally going to be recommended. Did this get slower/change significantly in performance? Many people have trouble with building Debug builds (no matter the host compiler) especially if they're using bfd-ld, since it's quite slow/uses a lot of memory. There are a few other issues to do with memory usage (do you have less than about a GB of RAM per CPU? Then you'll probably hit swapping by default & have a bad time - there are ways around that)<div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jan 2, 2020 at 5:42 PM Itaru Kitayama via llvm-dev <<a href="mailto:llvm-dev@lists.llvm.org">llvm-dev@lists.llvm.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi,<div><div>When building LLVM, is it always recommended to do it with the</div><div>latest official release, currently, it is 9.0.1?
