<p>I'd really like an *option* to make builds far more "deterministic" and "consistent" and "repeatable" from machine to machine, maybe similar-target to similar-target (OpenBSD/x86==Linux/x86==NetBSD/x86==Solaris/x86).</p>
<p><br>
</p>
<p>That is: I want the default to have full paths all over the place, but an option to reduce paths to something the same across all machines.</p>
<p><br>
</p>
<p>I want the C backend to by default have a bunch of line numbers to aid debugging, but an option (same option) to omit them.</p>
<p><br>
</p>
<p>Paths like Compiler.ThisFIle, if they have any slashes, should probably just always be forward.</p>
<p>This might break some workflows around copy/paste them into file.open dialogs on Windows though.</p>
<p>Much of Windows supports forward slashes, and much does not.</p>
<p><br>
</p>
<p>Maybe "-very-deterministic". Yes this is half joke -- deterministic is thought to be a boolean, and everything should be deterministic, but the definition of deterministic is actually unclear.</p>
<p><br>
</p>
<p>The "target" in reduce-target-variation isn't clearly the right name for this.</p>
<p>Maybe just reduce-variation or reduce-noise or more-reproducible.</p>
<p><br>
</p>
<p>This is a step toward a distribution form that isn't target-specific.</p>
<p>One run of the C backend could generate something redistributable to all or many targets.</p>
