Right, we actually depend on at least texture_env_combine in practice and that adds the ADD operation by itself. In theory we could perhaps use texture_env_add when texture_env_combine isn't available, but it doesn't seem worth it at this point. Fwiw, the only GPU I know of that doesn't at least have texture_env_combine is my ancient ATI Mach64 GPU. I agree that it's not worth the effort.
The Mach64 DRM module never made it into the kernel, afaik the Mach64 DDX driver is abandoned and the the mesa parts were removed from Mesa 8.0. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBAgAGBQJU7uyfAAoJEN0/YqbEcdMwtlYP/1g4d/E4g5dMNI7KinPYbx+Z 9MWhhUcegvC3rwNMMkJPSVSzR1WYbfDQgPCxuhKnMPuzNoa2ypviUuZArR/nhEZv +086ym1icpn0hAI+goDrL/DATcYyilHifM0gV5T64+4ieWMeNGrz8B4Jh3u9Bx3c lSJaKMH/e6Jos2Jp5MG37U97hSpdFsLL83RcQwXln67kMoucJOiqLvYnCDkzaD62 eAYZq8SucsupBGXNY0B6r6Q8/Z/geZsoiy6JzbFbvQgNJpnu1fvR3r4Bh8tejqOs P0WykVLOluHlnTuRMgaJYmr/WNOZAgWm+7YqoruIAlDgUAn9mGX01I6VwitI6xr8 zjoB4n4rhkMNCJy9uz6DC69IiRvqvEuB3KbshBUl6jGbBqxRjvGpz2AHgVzD2yy8 7whj9dtjq0wugI5saM2jSVuspSoVXxdO5igNL4RJLCA/IkPy8xwNvb1+dhzpchYv LAFPLu93Cy/OLA28mTcSfkwnwvbWhgSbBxyFhAaHfO8BDEjTJpDuULrnzs4q6KXb yvhHeIzXbBMVlMOk8PuIjOEEIyJhas7Nea4LJcOFyFs0CLNNpFNKq0UKsOm48Orj 0CHThLenyVwdlm3WDzXfPf2l84gLE8t6ev6SVKn+5EapfMEnDWKvHMkeL43sQ04j vfoFB4Ox+ZX6uZ35MAip =r+WW -----END PGP SIGNATURE-----
