If it doesn't work, maybe because the binaries call dlopen or depend on the way dynamic linking works, you might be able to use a research tool I developed last year that helps analyze/optimize dynamically linked code as if it were statically linked.

In other words, suppose that the bitcode files for the program and all shared libraries are available. Also, suppose that the libraries can not be linked, statically.
Is it possible to run an analysis (e.g., taint analysis or constant propagation) on the whole user level software stack (at the IR level)? If not, is there any better approach?<br></div><div>Regards.<br></div></div><div>______________________________<wbr>_________________<br></div><div>LLVM Developers mailing list<br></div><div><a href="mailto:llvm-dev@lists.llvm.org" rel="noreferrer noreferrer" target="_blank">llvm-dev@lists.llvm.org</a><br></div><div><a href="https://urldefense.com/v3/__https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-dev__;!!DZ3fjg!u4VQPAnIiZn7aZ7cCB30yAsuwi4iG2eMe2cGZ5zGFYuMB1KV04QbMyHyE3rITRoX7Bs$" rel="noreferrer noreferrer noreferrer" target="_blank">https://lists.llvm.org/cgi-<wbr>bin/mailman/listinfo/llvm-dev</a><br></div></blockquote></div></blockquote></div><div>______________________________<wbr>_________________<br></div><div>LLVM Developers mailing list<br></div><div><a href="mailto:llvm-dev@lists.llvm.org" rel="noreferrer" target="_blank">llvm-dev@lists.llvm.org</a><br></div><div><a href="https://urldefense.com/v3/__https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-dev__;!!DZ3fjg!u4VQPAnIiZn7aZ7cCB30yAsuwi4iG2eMe2cGZ5zGFYuMB1KV04QbMyHyE3rITRoX7Bs$" rel="noreferrer noreferrer" target="_blank">https://lists.llvm.org/cgi-<wbr>bin/mailman/listinfo/llvm-dev</a><br></div></blockquote></div><div><br></div><div><br></div><div>-- <br></div><div><br></div><div dir="ltr"><div>Jakub Kuderski<br></div></div></blockquote></div></blockquote></div><div><br></div><div><b>Attachments:</b><br></div><ul><li>ATT00001.txt<br></li></ul></blockquote><div><br></div></body></html>
