Hi Sylvestre,<br>
<br>
Thx again, and i indeed did a build without any dependency on libgcc
(clang / libcxx / lld / compiler-rt / libunwind ... version 6.0.1)
on Ubuntu 16.04.<br>
The main difficulty was the dependency of compiler-rt on libunwind
and in the end the result was not 100% satisfying since on every
link -L/usr/local/lib had to be given to not pull in the wrong
(system) libunwind (in fact i removed the system libunwind-dev, link
line without hassles now, but not 100% satisfying as well).<br>
Not depending (runtime dependency) on libgcc would be a further
improvement for apt.llvm.org IMO.<br>
There still would be a dependency an crtbegin / crtend, but this is
lacking an official solution by now and is only a link time
dependency.<br>
<br>
Best regards<br>
<br>
Franz<br>
<br>
P.S.<br>
<br>
Another possible improvement here would be lld supporting file based
configuration (e.g. /usr/local lib first) and / or linker scripts.<br>

<div>I didn't investigating replacing libgcc. Would you have
some doc on this to evaluate the complexity?</div>

<br>
Today i noticed that on <a href="http://apt.llvm.org"
rel="noreferrer" target="_blank" moz-do-not-send="true">apt.llvm.org</a>
now with clang / llvm 7 there are<br>
packages for libcxx / libcxxabi (not available in previous
versions),<br>
thanks.<br>
Which amounts to the next level of "perfection": Would it be
possible to<br>
craft packages which depend on compiler-rt instead of libgcc?<br>
<br>
Best regards<br>
