<div dir="ltr">Hi all,<div><br></div><div>Up until now, we (Google/Android) had been focused on Ubuntu 12.04 x86_64 LTS, using a custom libedit (July 2013) and gcc 4.8.2 as our primary target Linux system.</div><div><br></div>
<div>As of today, I've upgraded our focus to Ubuntu 14.04 x86_64, building with the clang 3.5 package from Ubuntu and using the stock system libedit. I happen to focus on using the gold linker, but I do switch between that and the bfd linker.</div>
<div><br></div><div>For debug builds using cmake and ninja, I get the following timing numbers on my newly-built Ubuntu 14.04 x86_64-based box on a 32-core machine with a clean build of lldb:</div><div><br></div><div>g++ 4.8.2/ld.bfd (stock) linker: 7.5 minutes</div>
<div><div>g++ 4.8.2/ld.gold linker: 6.0 minutes</div><div>clang-3.5/ld.gold linker: 4.9 minutes</div>-- <br><div dir="ltr">-Todd</div>
