android-x86-mesa.git/src/glsl/builtins, branch android-x86-2.2 Androïd/x86 port of Mesa drivers https://git.hiegel.fr/cgit/android-x86-mesa.git/atom?h=android-x86-2.2 2010-11-30T21:48:28Z glsl: Lazily import built-in function prototypes. 2010-11-30T21:48:28Z Kenneth Graunke kenneth@whitecape.org 2010-11-11T20:11:27Z urn:sha1:f5692f452f7ae77d1e710041ffebb468cc5ba87b This makes a very simple 1.30 shader go from 196k of memory to 9k. NOTE: This -may- be a candidate for the 7.9 branch, as the benefit is substantial. However, it's not a simple change, so it may be wiser to wait for 7.10. glsl: Reimplement the "cross" built-in without ir_binop_cross. 2010-11-17T21:20:30Z Kenneth Graunke kenneth@whitecape.org 2010-11-17T21:20:30Z urn:sha1:671ccf593e1079d0f3e1adf42831d09da91a2b68 We are not aware of any GPU that actually implements the cross product as a single instruction. Hence, there's no need for it to be an opcode. Future commits will remove it entirely. glsl: Implement the asinh, acosh, and atanh built-in functions. 2010-11-15T22:02:52Z Kenneth Graunke kenneth@whitecape.org 2010-11-15T21:58:51Z urn:sha1:db9b8c062fe8ebb7321a24207f2887a28b31a55d generate_builtins.py: Fix inconsistent use of tabs and spaces warning. 2010-11-15T22:02:52Z Kenneth Graunke kenneth@whitecape.org 2010-11-15T22:00:03Z urn:sha1:096d36872ff531b0295109165cb90ea63be7a1b1 glsl/builtins: Clean up some ugly autogenerated code in atan. 2010-11-03T20:39:41Z Kenneth Graunke kenneth@whitecape.org 2010-10-31T04:59:52Z urn:sha1:91b72864b0b774a25712cf7e5196a22acc1693d9 In particular, calling the abs function is silly, since there's already an expression opcode for that. Also, assigning to temporaries then assigning those to the final location is rather redundant. glsl/builtins: Rename 'x' to 'y_over_x' in atan(float) implementation. 2010-11-03T20:39:41Z Kenneth Graunke kenneth@whitecape.org 2010-10-31T04:51:01Z urn:sha1:84566c770a8742638ff11fbae59756a50513d621 For consistency with the vec2/vec3/vec4 variants. generate_builtins.py: Output large strings as arrays of characters. 2010-10-21T18:45:38Z Kenneth Graunke kenneth@whitecape.org 2010-10-21T18:42:45Z urn:sha1:2cacaf6e7b9bc38efd47413b5e667b6e750698b8 This works around MSVC's 65535 byte limit, unfortunately at the expense of any semblance of readability and much larger file size. Hopefully I can implement a better solution later, but for now this fixes the build. glsl: Add support for GLSL 1.30's modf built-in. 2010-10-21T07:14:37Z Kenneth Graunke kenneth@whitecape.org 2010-10-19T18:56:47Z urn:sha1:574c53f551cb35173aee4acfa5c374613b953264 glsl: Add support for the 1.30 round() built-in. 2010-10-14T22:59:47Z Kenneth Graunke kenneth@whitecape.org 2010-10-14T21:33:30Z urn:sha1:27ced5c5ff907557007ed6cb78cef5810cf48ef5 This implements round() via the ir_unop_round_even opcode, rather than adding a new opcode. We may wish to add one in the future, since it might enable a small performance increase on some hardware, but for now, this should suffice. glsl: Add front-end support for GLSL 1.30's roundEven built-in. 2010-10-14T22:59:47Z Kenneth Graunke kenneth@whitecape.org 2010-10-14T20:40:26Z urn:sha1:6dc204c5dc723bbf9337aa7787cd6cc309a24285 Implemented using the op-code introduced in the previous commit.
