<p class="MsoNormal">Forgive me if this is common knowledge amongst the more experienced here, but I’m currently confused by the lit regression tests.<o:p></o:p></p>
<p class="MsoNormal">I’m currently working to validate a Clang/LLVM toolchain, hosted on a Mac OS, which only supports a select number of baremetal ARM targets.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Specifically, the test Driver/darwin-ld-dedup.c fails due to not having available targets compatible with ‘x86_64-apple-macosx10.6.0’. As far as I’m concerned, this target is a do-not-care for me.<o:p></o:p></p>
<p class="MsoNormal">Another that seems suspect is Index/pch-from-libclang.c, which also sets the triple directly to x86_64-apple-darwin.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My target triple does indeed look correct (arch is arm), and the host triple is x86_64-apple-darwin*.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Lit supports REQUIRED checking the target triple, but such checks just don’t appear in these failing tests.<o:p></o:p></p>
<p class="MsoNormal">Is this not a common enough problem, or might I be missing something fundamental in my understanding?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
