* glsl: Add a "ubo_load" expression type for fetches from UBOs.Eric Anholt2012-08-073-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers will probably want to be able to take UBO references in a shader like: uniform ubo1 { float a; float b; float c; float d; } void main() { gl_FragColor = vec4(a, b, c, d); } and generate a single aligned vec4 load out of the UBO. For intel, this involves recognizing the shared offset of the aligned loads and CSEing them out. Obviously that involves breaking things down to loads from an offset from a particular UBO first. Thus, the driver doesn't want to see variable_ref(ir_variable("a")), and even more so does it not want to see array_ref(record_ref(variable_ref(ir_variable("a")), "field1"), variable_ref(ir_variable("i"))). where a.field1[i] is a row_major matrix. Instead, we're going to make a lowering pass to break UBO references down to expressions that are obvious to codegen, and amenable to merging through CSE. v2: Fix some partial thoughts in the ir_binop comment (review by Kenneth) Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

* glsl: Refactor #version validation to be more future-proof.Kenneth Graunke2012-07-313-38/+16
| | | | | | | | | | | | | | | | | The previous implementation required a flag in _mesa_glsl_parse_state and line of code to initialize it for every version of the shading language we intend to support. As we look to add 150, 330, 400, 410, 420, and beyond, this gets rather unwieldy. This patch retains the switch statement (to reject, say, #version 111), but removes all the bits. Code to check for ctx->API == API_OPENGL_CORE could easily be added to the 110 and 120 cases to reject those. v2: Use _mesa_is_desktop_gl to preserve the existing behavior in the presence of the new API_OPENGL_CORE enumeration.

| | | | | | | | | | | | | | | | | | | | | Previously, the code for setting this flag for GLSL programs was duplicated in three places: brw_link_shader(), glsl_to_tgsi_visitor, and ir_to_mesa_visitor. In addition to the unnecessary duplication, there was a performance problem on i965: brw_link_shader() set the flag before doing its final round of optimizations, which meant that if the optimizations managed to eliminate all the discard operations, the flag would still be set, resulting (at least in theory) in slower performance. This patch consolidates all of the code that sets UsesKill for GLSL programs into do_set_program_inouts(), which already is doing a similar job for UsesDFdy, and which occurs after i965's final round of optimizations. Non-GLSL programs (ARB programs and the state tracker's glBitmap program) are unaffected. Reviewed-by: Eric Anholt <[email protected]>
