[Mesa-dev] [PATCH 24/88] glsl: compile shaders when program not found in cache

[Timothy Arceri]

We may have seen the individual shaders before and skipped compiling
but they may not have been used together in this combination before.

We could probably only compile the shaders which were skipped here
but we need to be careful because the source may also have been
changed since the last compile so for now we just recompile
everything.
