Right now, I'm working on moving a bunch of code into a new static library called libformat that can be independently developed and *tested*. One of the problems we had before was that the only format-conversion testing we did was through piglit which can't actually hit all of the code-paths. Hopefully, splitting it out will make it easier to test and easier to combine efforts than gallium depending on mesa or the other way around. > > BTW, this series will conflict with the big endian work that Richard > Sandiford is doing. > Yeah, I'm aware of that. --Jason Ekstrand
