<div dir="ltr">I agree with Jordan (and Chris) on this. I think that we should try to simplify the build process that we have rather than encouraging more build script wrappers. The current build process is pretty cumbersome which is why I think that many people have wrapper scripts. In fact, it seems that it is complicated enough that we need a wrapper script officially (aka build-script). I think that we should aim to break down the pieces a bit further and encourage it to be more like LLVM where even though there are multiple projects, there is no need for a wrapper script, instead everything works out of the box with minimal tweaks.<div><div><br></div><div>That said, something like Chris' idea of a bisection script seems quite valuable, especially given the interdependencies between LLVM, clang, and swift.</div><div><br></div><div><div class="gmail_extra"><div class="gmail_quote">On Sat, Oct 21, 2017 at 9:10 AM, Chris Lattner via swift-dev <span dir="ltr"><<a href="mailto:swift-dev@swift.org" target="_blank">swift-dev@swift.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Any scripts should be subject to the same code review and design policies as the rest of the compiler. A bisection script or build-script seem fine, but a four line script to automate something is probably not the right thing to include.<br>

So I propose to create a sub-folder, e.g. ‘dev-scripts’ to place such scripts (just for new scripts, I’m not proposing moving existing scripts). The intention is to keep the bar low to contribute to dev-scripts. So scripts may be not super-polished and it’s also ok to have multiple scripts which do similar things.<br>
