[Mesa-dev] [PATCH v3 00/29] add fp64 support to mesa and glsl compiler

[Ilia Mirkin]

I just sent out a few updated patches (latest can be seen in
https://github.com/imirkin/mesa/commits/fp64-5) -- with all that in
place the mysterious failure in one of the initializer tests is gone,
and the constbuf locations being used correspond to the ones that we
expect instead of having *tons* of empty space.
