| * (GL_MAX_VERTEX_ATTRIBS / 3) dmat3x2, |

| * (GL_MAX_VERTEX_ATTRIBS / 6) dmat3 and dmat3x4, |
| * (GL_MAX_VERTEX_ATTRIBS / 8) dmat4x3 and dmat4, |
| * attributes can be used in each shader stage at the same time. |
| * |
| * The test should run in 7 iterations: |
| * |
| * a) In the first iteration, (GL_MAX_VERTEX_ATTRIBS / 2) double |
| * attributes and (GL_MAX_VERTEX_ATTRIBS / 2) dvec2 attributes |
| * should be defined in a vertex shader. The test should verify |
| * the values exposed by these attributes and write 1 to an |
| * output variable if all attribute values are found to be |
| * correct, or set it to 0 if at least one of the retrieved |
| * values is found invalid. |
| * |
| * Double attributes should be assigned the value: |
| * (n_attribute + gl_VertexID * 2) |
| * |
| * Dvec2 attribute components should be assigned the following |
| * vector values: |
| * (n_attribute + gl_VertexID * 3 + 1, |
| * n_attribute + gl_VertexID * 3 + 2) |
| * |
| * b) In the second iteration, (GL_MAX_VERTEX_ATTRIBS / 4) dvec3 |
| * and (GL_MAX_VERTEX_ATTRIBS / 4) dvec4 attributes should be |
| * defined in a vertex shader. Verification of the data exposed |
| * by these input variables should be performed as in step a), |
| * with an exception of the values passed through the attributes. |
| * |
| * Dvec3 attribute components should be assigned the following |
| * vector values: |
| * (n_attribute + gl_VertexID * 3 + 0, |
| * n_attribute + gl_VertexID * 3 + 1, |
| * n_attribute + gl_VertexID * 3 + 2). |
| * |
| * Dvec4 attribute components should be assigned the following |
| * vector values: |
| * (n_attribute + gl_VertexID * 4 + 0, |
| * n_attribute + gl_VertexID * 4 + 1, |
| * n_attribute + gl_VertexID * 4 + 2, |
| * n_attribute + gl_VertexID * 4 + 3). |
| * |
| * n_attribute corresponds to the ordinal number of each attribute, |
| * as defined in the shader. |
| * |
| * c) In the third iteration, (GL_MAX_VERTEX_ATTRIBS / 2) dmat2 attributes |
| * should be defined in a vertex shader. Verification of the data exposed |
| * by these input variables should be performed as in step a), with an |
| * exception of the values passed through the attributes. |
| * |
| * Subsequent matrix elements should be assigned the following value: |
| * (n_type + n_attribute + gl_VertexID * 16 + n_value) |
| * |
| * n_type corresponds to the ordinal number of type as per the |
| * order at the beginning of the paragraph. |
| * n_value corresponds to the ordinal number of the element. |
| * |
| * d) In the fourth iteration, (GL_MAX_VERTEX_ATTRIBS / 8) dmat3x2 and |
| * (GL_MAX_VERTEX_ATTRIBS / 8) dmat4x2 attributes should be defined in a |
| * vertex shader. Verification of the data exposed by these input |
| * variables should be performed as in step a), with an exception of the |
| * values passed through the attributes. |
| * |
| * Use the same element values as in step c) |
| * |
| * e) In the fifth iteration, (GL_MAX_VERTEX_ATTRIBS / 8) dmat2x3 and |
| * (GL_MAX_VERTEX_ATTRIBS / 8) dmat2x4 attributes should be defined in a |
| * vertex shader. Verification of the data exposed by these input |
| * variables should be performed as in step a), with an exception of the |
| * values passed through the attributes. |
| * |
| * Use the same element values as in step c) |
| * |
| * f) In the sixth iteration, (GL_MAX_VERTEX_ATTRIBS / 12) dmat3 and |
| * (GL_MAX_VERTEX_ATTRIBS / 12) dmat3x4 attributes should be defined in a |
| * vertex shader. Verification of the data exposed by these input |
| * variables should be performed as in step a), with an exception of the |
| * values passed through the attributes. |
| * |
| * Use the same element values as in step c) |
| * |
| * g) In the seventh iteration, (GL_MAX_VERTEX_ATTRIBS / 16) dmat4x3 and |
| * (GL_MAX_VERTEX_ATTRIBS / 16) dmat4 attributes should be defined in a |
| * vertex shader. Verification of the data exposed by these input |
| * variables should be performed as in step a), with an exception of the |
| * values passed through the attributes. |
| * |
| * Use the same element values as in step c) |
| * |
| * h) Modify the language of cases a) - g), so that instead of separate |
| * attributes, all attributes of the same type are now a single arrayed |
| * attribute. |
| * |
| * Vertex shaders from both iterations should be used to form two program |
| * objects. 1024 vertices should be used for a non-indiced GL_POINTS |
| * draw call, made using those two programs. |
| * |
| * All glVertexAttribL*() and glVertexAttribLPointer() should be used for |
| * the purpose of the test. The following draw call API functions should be |
| * tested: |
| * |
| * a) glDrawArrays() |
| * b) glDrawArraysInstanced(), primcount > 1, zero vertex attrib divisor |
| * c) glDrawArraysInstanced(), primcount > 1, non-zero vertex attrib divisor |
| * d) glDrawElements() |
| * e) glDrawElementsInstanced(), properties as in b) |
| * f) glDrawElementsInstanced(), properties as in c) |
| * |
| * All shaders used by the test should come in two flavors: |
| * |
| * - one where attribute locations are explicitly defined in the body; |
| * - the other one where attribute locations are to be assigned by |
| * the compiler. |
| * |
| * For each shader, the test should make sure that all attributes have |
| * been assigned correct amount of locations. (eg: dvec4 attribute |
| * should be granted exactly one location). |
| * |
| * Data stored in output variables should be XFBed to the test. |
| * The test passes if the retrieved values are found to be valid |
| * for all vertex shader invocations. |
