* i965: Fix flat integral varyings.Paul Berry2011-10-312-3/+5
| | | | | | | | | | | | | | | | | Previously, the vertex and fragment shader back-ends assumed that all varyings were floats. In GLSL 1.30 this is no longer true--they can also be of integral types provided that they have an interpolation qualifier of "flat". This required two changes in each back-end: assigning the correct type to the register that holds the varying value during shader execution, and assigning the correct type to the register that ties the varying value to the rest of the graphics pipeline (the message register in the case of VS, and the payload register in the case of FS). Fixes piglit tests fs-int-interpolation and fs-uint-interpolation. Acked-by: Kenneth Graunke <[email protected]>
* mesa: Add glsl_type::get_scalar_type() function.Paul Berry2011-10-312-0/+34
| | | | | | | | This function is similar to get_base_type(), but when called on arrays, it returns the scalar type composing the array. For example, glsl_type(vec4[]) => float_type. Acked-by: Kenneth Graunke <[email protected]>
* i965/gen6+: Switch GLSL from ALT to IEEE floating point modePaul Berry2011-10-314-6/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | i965 graphics hardware has two floating point modes: ALT and IEEE. In ALT mode, floating-point operations never generate infinities or NaNs, and MOV instructions translate infinities and NaNs to finite values. In IEEE mode, infinities and NaNs behave as specified in the IEEE 754 spec. Previously, we used ALT mode for all vertex and fragment programs, whether they were GLSL programs or ARB programs. The GLSL spec is sufficiently vague about how infs and nans are to be handled that it was unclear whether this mode was compliant with the GLSL 1.30 spec or not, and it made it very difficult to test the isinf() and isnan() functions. This patch changes i965 GLSL programs to use IEEE floating-point mode, which is clearly compliant with GLSL 1.30's inf/nan requirements. In addition to making the Piglit isinf and isnan tests pass, this paves the way for future support of the ARB_shader_precision extension. Unfortunately we still have to use ALT floating-point mode when executing ARB programs, because those programs require 0^0 == 1, and i965 hardware generates 0^0 == NaN in IEEE mode. Fixes piglit tests "isinf-and-isnan fs_fbo", "isinf-and-isnan vs_fbo", and {fs,vs}-{isinf,isnan}-{vec2,vec3,vec4}.
* glsl: Add isinf() and isnan() builtins.Paul Berry2011-10-314-4/+34
| | | | | | | | | | | | | The implementations are as follows: isinf(x) = (abs(x) == +infinity) isnan(x) = (x != x) Note: the latter formula is not necessarily obvious. It works because NaN is the only floating point number that does not equal itself. Fixes piglit tests "isinf-and-isnan fs_basic" and "isinf-and-isnan vs_basic".
* glsl: Add '.ir' extension to builtin IR filesPaul Berry2011-10-3166-3/+9
| | | | | | | | This patch adds the extension '.ir' to all the files in src/glsl/builtins/ir/, and changes generate_builtins.py so that it no longer globs on '*' to find the files to build. This prevents spurious files (such as EMACS' infamous *~ backup files) from breaking the build.
* glsl: Fix copy-paste error in constant_expression_value(ir_binop_nequal)Paul Berry2011-10-311-1/+1
| | | | | | | | | | | The implementation of ir_binop_nequal in constant_expression_value() appears to have been copy-and-pasted from the implementation of ir_binop_equal, but with all instances of '==' changed to '!='. This is correct except for one minor flaw: one of those '==' operators was in an assertion checking that the types of the two arguments were equal. That one needs to stay an '=='. Fixes piglit tests {fs,vs}-inline-notequal.

* svga: Flush the hwtnl primitives before writing to buffers.José Fonseca2011-10-315-4/+62
| | | | | | | | | | | | | | | svga keeps a small queue of similar primitive draws in order to coalesce them into a single draw primitive command. But the buffers referred in primitives not yet emitted were being ignored in the considerations to flush or not the context. This fixes piglit vbo-map-remap, vbo-subdata-sync, vbo-subdata-zero, and Seeker. Based on investigation and patch from Brian Paul. Reviewed-By: Brian Paul <[email protected]>
