1085648 - libvpx gained a dependency on some recent version of xcode/clang for AVX2 support

Status: RESOLVED WONTFIX

(Core :: WebRTC, defect)

Description

[Randell Jesup [:jesup] (needinfo me)]

Either:
Force everyone to update clang and xcode (and recent xcodes only work on 10.9.x), or
We should make it cleanly build if you don't have AVX2 support in xcode/clang.

I'll attach a patch generated by modifying update.py per rillian's instructions and running it.  Note I don't have ndk installed so I commented out one target.  I also had to modify moz.build trivially.

This builds and runs on OSX 10.7.5 & XCode 4.6.3 (clang (apple) 4.2 (425.0.28) based on clang 3.2svn.

rillian - is this resolved now?

I'm fine to wontfix it if you are. We still require AVX intrinsics to build, but I upgraded to 10.10 so I can't easily verify the dependency on older xcode. We do build with whatever clang the 10.8 builders use though, so maybe Apple pushed an update?

Note that the parts of the patch touching libvpx code itself are out of date.

We haven't done anything about this issue for several months. Giving up.
