Patch for rhel-alt-7.4, once branch is created none

Description Laszlo Ersek 2017-06-15 11:44:32 UTC 
+++ This bug was initially created as a clone of Bug #1429050 +++

The exact same issue as described in bug 1429050 happens in RHEL-7.4 as well, using package "mesa-private-llvm-3.9.1-3.el7.aarch64".

Jeremy's patch in bug 1429050 comment 4 (direct link: attachment 1261680 [details]) applies to the above-mentioned RHEL-7.4 package (i.e., dist-git commit 6ec0b20b46c9) without conflicts, and works fine:

http://people.redhat.com/lersek/a95d492b-9f7a-4ba5-a6a4-a030f66bcae8-pegas10-aarch64-gnome.png

Please branch the "mesa-private-llvm" package for Pegas-1.0, and incorporate the patch.
Comment 2 Igor Gnatenko 2017-06-15 12:20:48 UTC 
Please, can you create new bugs instead of cloning them? Me (and probably all others who were CCed on original bug) don't want to see RHEL-related bugs.
