<div>Hello clang developers,<br>
<br>
</div>
Recently I've run into issue where gcc outperforms clang by
many factors. After investigation and profiling I've noticed
that calls to some complex numbers operations like "cabs"
aren't inlined but rather dynamically linked (which doesn't
happen in case of gcc). Further investigation shows that
(looking at lib/CodeGen/CGBuiltin.cpp) clang has very few
basic builtins for complex numbers and missing out some
important ones, is there any reason why wasn't this
implemented? And if there is no reason, is there a possibility
to have such feature in clang? I could possibly add some of
these functions, as I'm a student and I'd feel great to have
some lines of code in clang compiler. <br>
