<div class="">Hello,</div>
<div class=""><br class="">
</div>
<div class="">Is there a combination of the current tools would would allow me to apply LTO to a set of object files where are less than an entire application? Similar to “ld –r” for doing a partial link.</div>
<div class="">I assume it would start with “clang –flto –c {a,b,c}.c” but the a subsequent link step fails do to unresolved references of course.</div>
<div class="">Using llvm-link will linke the bitcode files but does not trigger compilation.</div></div></div></blockquote><div><br class=""></div><div>You can llvm-link and then run clang. Note that the result of LTO in this case is not as powerful as when it is linker driver, since you can’t internalize.</div><div>You may also want to look at llvm-lto, but it can be annoying because it requires (AFAIK) an export list.</div><div><br class=""></div><div>What is your use-case?</div><div><br class=""></div><div>— </div><div>Mehdi</div><div><br class=""></div><div><br class=""></div><br class=""><blockquote type="cite" class=""><div class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; font-size: 14px; font-family: Calibri, sans-serif;" class="">
