linker: Eliminate more dead code after demoting shader inputs and outputs

Consider the following vertex shader and fragment shader:

Since the fragment shader does not use 'v', it is demoted from a
varying to a simple global variable.  Once that happens, the
assignment to 'v' is useless, and it should be removed.  In addition,
'u' is no longer active, and it should also be removed.

Performing extra dead code elimination after demoting shader inputs
and outputs takes care of this.  This elimination must occur before
assigning uniform locations, or the declaration of 'u' cannot be
removed.

This change *breaks* the piglit test getuniform-01, but that test is
already incorrect.  The test uses a vertex shader that assigns to a
user-defined varying, but it has no fragment shader.  Since Mesa does
not support ARB_separate_shader_objects (we only support the EXT
version), the linker correctly eliminates the user-defined varying.
The cascading effect is that the uniform queried by the C code of the
test is also (correctly) eliminated.

glsl: Add uniform_locations_assigned parameter to do_dead_code opt pass

Setting this flag prevents declarations of uniforms from being removed
from the IR.  Since the IR is directly used by several API functions
that query uniforms in shaders, uniform declarations cannot be removed
after the locations have been set.  However, it should still be safe
to reorder the declarations (this is not tested).

annoying.  I could never seem to remember which one was reversed, which
made it harder to find quickly.  "Max __ Threads" seems more natural.

13 years agoi965: Remove "single threaded" INTEL_DEBUG mode.

i965: Remove "single threaded" INTEL_DEBUG mode.

According to the docs for 3DSTATE_PS (Gen7+) and 3DSTATE_WM (Gen6),
there is a platform dependent value for the minimum number of pixel
shader threads.  It may also vary based on whether WIZ Hashing is on.

For example, Ivybridge requires at least 4 threads if WIZ hashing is
disabled, and 8 if it's enabled.  Programming it to use less threads is
illegal.  Sandybridge appears to have similar restrictions.

So on newer platforms, INTEL_DEBUG=sing will probably just hang the GPU.
Rather than try to patch it up for newer platforms and extend it to
support geometry shaders, just remove it as it isn't that useful anyway.

13 years agomesa: Remove unnecessary and incorrect TexEnv parameter validation.

mesa: Remove unnecessary and incorrect TexEnv parameter validation.

For GL_RGB_SCALE and GL_ALPHA_SCALE targets, the API wrapper code
attempts to ensure the parameter is 1.0, 2.0, or 4.0.

This is unnecessary: set_combiner_scale in texenv.c (called by
_mesa_TexEnvfv) already checks this and raises an appropriate error.

It's also incorrect: For glTexEnvx, the API validation code directly
compares the GLfixed input parameter with a floating point constant,
prior to converting fixed-point to floating point.

Fixes an issue in the OpenGL ES 1.1 conformance suite.
