* glsl: Fix prorgram interface query locations biasing for SSO.Kenneth Graunke2016-04-011-8/+3
| | | | | | | | | | | | | | | | | | | | | With SSO, the GL_PROGRAM_INPUT and GL_PROGRAM_OUTPUT interfaces refer to the first and last shader stage linked into a program. This may not be the vertex and fragment shader stages. So, subtracting VERT_ATTRIB_GENERIC0 and FRAG_RESULT_DATA0 is bogus. We need to subtract VERT_ATTRIB_GENERIC0 for VS inputs, FRAG_RESULT_DATA0 for FS outputs, and VARYING_SLOT_VAR0 for other cases. Note that built-in variables get a location of -1.

| | | | | | | | | | | | | | | | | | | | System values are just built-in input variables that we've opted to special-case out of convenience. We need to consider all inputs, regardless of how we've classified them. Unfortunately, there's one exception: we shouldn't add gl_BaseVertex unless ARB_shader_draw_parameters is enabled, because it doesn't actually exist in the language, and shouldn't be counted in the GL_ACTIVE_RESOURCES query.

* Revert "i965: Don't add barrier deps for FB write messages."Matt Turner2016-03-301-4/+3
| | | | | | | | | | | | | | This reverts commit d0e1d6b7e27bf5f05436e47080d326d7daa63af2. The change in the vec4 code is a mistake -- there's never an FS_OPCODE_FB_WRITE in vec4 code. The change in the fs code had the (harmless) effect of not recognizing an FB_WRITE as a scheduling barrier even if it was marked EOT -- harmless because the scheduler marked the last instruction of a block as a barrier, something I'm changing in the following patches. This will be reimplemented later in the series.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here we use the built-in validation in ast_layout_expression::process_qualifier_constant() to check for mismatching global out strides on buffers in a single shader. From the ARB_enhanced_layouts spec: "While *xfb_stride* can be declared multiple times for the same buffer, it is a compile-time or link-time error to have different values specified for the stride for the same buffer." For intrastage validation a new helper link_xfb_stride_layout_qualifiers() is created. We also take this opportunity to make sure stride is at least a multiple of 4, we will validate doubles at a later stage. From the ARB_enhanced_layouts spec: "If the buffer is capturing any double-typed outputs, the stride must be a multiple of 8, otherwise it must be a multiple of 4, or a compile-time or link-time error results." Finally we update store_tfeedback_info() to apply the strides to LinkedTransformFeedback and update the buffers bitmask to mark any global buffers with a stride as active. For example a shader with: layout (xfb_buffer = 0, xfb_offset = 0) out vec4 gs_fs; layout (xfb_buffer = 1, xfb_stride = 64) out; Is expected to have a buffer bound to both 0 and 1.
