This tried to de-duplicate identical copies of the same shader assembly, but in the least efficient way possible: it did a linear walk through every shader in the entire context memcmp'ing the final assembly (after going through the effort to compile it). In the end, all it saved was space and number of BOs, not even state changes. This optimization has been mostly replaced by st/mesa's cache mechanism, which looks for multiple shaders that compile to the same NIR and go further than this did, and actually reuse the same pipe shader state. That's even more efficient than this. This seems to still trigger some times, because the NIR that st/mesa hashes hasn't quite been finalized and stripped. But it would be better to improve that, not this. Reviewed-by: Jason Ekstrand <jason@jlekstrand.net> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8634>
