<html><head></head><body>The problem is a bitcode implementation that has a stdcall function that's used from native code. 1 side has _elements_exception_handler, compiled that would be __elements_exception_handler@20 due to stdcall. The native bit has the mangled name and the linker can't find it as the bitcode indexes have it without mangling.<br>
<br>
I'll try to prepare a testcase when I get back in the office.<br><br><div class="gmail_quote">Rui Ueyama <ruiu@google.com> schreef op 30 maart 2018 19:17:06 CEST:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

When having thinlto enabled in both ends the same thing happens (but bitcode on both ends works fine)<br>
