[Mesa-dev] [PATCH 0/6] glsl_to_tgsi: Further improvement of lifetime tracking for register merge

[Gert Wollny]

I Just wanted to add that the code is now also available from

https://github.com/gerddie/mesa/tree/lifetime-update-v1

re-based against 15e208c4. 

(I waited for "wayland-egl: adds CFLAGS for wayland.egl.h include" 
to have a green board on travis-ci) 

Best, 
Gert
