Git-commit: 041b18cf23a0acf7b0eddf63cd7a2a10192432a1 Author: Timothy Arceri Subject: st/shader_cache: restore num_tgsi_tokens when loading from cache References: bnc#1079465 fdo#104762 Patch-Mainline: Upstream Signed-off-by: Michal Srb Without this we will fail to correctly serialise programs when using glGetProgramBinary() if the program was retrieved from the disk cache rather than freshly compiled.
