This was just ignored (unless for some reason like unfilled polys draw was
handling this).
I'm not convinced of that code, putting the float for the clamp in the key
isn't really a good idea. Then again the other floats for depth bias are
already in there too anyway (should probably have a jit_context for the
setup function), so this is just a quick fix.
Also, the "minimum resolvable depth difference" used isn't really right as it
should be calculated according to the z values of the current primitive
and not be a constant (of course, this only makes a difference for float
depth buffers), at least for d3d10, so depth biasing is still not quite right.

This patch fixes segfaults observed when enabling the post processing
features. When the format is not supported, or a texture cannot be
created, the code must gracefully handle failure and report the error to
the calling code for proper failure handling.
To accomplish this the following changes were made to the filters.h
prototypes:
- bool return for pp_init_func
- Added pp_free_func for filter specific resource destruction
Fixes segfaults from backtraces:
* util_destroy_blit
pp_free
* u_transfer_inline_write_vtbl
pp_jimenezmlaa_init_run
pp_init
This patch also uses tgsi_alloc_tokens to allocate temporary tokens in
pp_tgsi_to_state, instead of allocating the array on the stack. This
fixes the following stack corruption segfault in pp_run.c:
* _int_free
aaline_delete_fs_state
pp_free

OpenGL doesn't support this but d3d10 does.
It is a bit of a pain as it is necessary to keep track of queries
still active at the end of a scene, which is also why I cheat a bit
and limit the amount of simultaneously active queries to (arbitrary)
16 (simplifies things because don't have to deal with a real list
that way). I can't think of a reason why you'd really want large
numbers of overlapping/nested queries so it is hopefully fine.
(This only affects queries which need to be binned.)
v2: don't copy remainder of array when deleting an entry simply replace
the deleted entry with the last one (order doesn't matter).

Previously lp_rast_begin_query commands were always inserted into each bin,
and re-issued if the scene was restarted, while lp_rast_end_query commands
were executed for each still active query at the end of tile rasterization.
Also, the ps_invocations and vis_counter were set to zero when the respective
command was encountered.
This however cannot work for multiple queries of the same type (note that
occlusion counter and occlusion predicate while different type were also
affected).
So, change the logic to always set the ps_invocations and vis_counter to zero
at the start of tile rasterization, and then use "start" and "end" per-thread
query values when encountering the begin/end query commands instead, which
should work for multiple queries of the same type. This also means queries do
not have to be reissued in a new scene, however they still need to be finished
at end of tile rasterization, so a list of queries still active at the end of
a scene needs to be maintained.
Also while here don't bin the queries which don't do anything in rasterization.
(This change does not actually handle multiple queries of the same type yet,
as the list of active queries is just a simple fixed array and setup can still
only have one query active per type.)

This has the (intended!) side effect that vertex shader inputs and
fragment shader outputs will appear in the IR in the same order that
they appeared in the shader code. This results in the locations being
assigned in the declared order. Many (arguably buggy) applications
depend on this behavior, and it matches what nearly all other drivers
do.
Fixes the (new) piglit test attrib-assignments.
NOTE: This is a candidate for stable release branches (and requires the
previous commit to prevent a regression in OpenGL ES 2.0 conformance
test stencil_plane_operation).

The checks to determine when the data can be uploaded in an interleaved
fashion can be tricked by certain data layouts. For example,
float data[...];
glVertexAttribPointer(0, 4, GL_FLOAT, GL_FALSE, 16, &data[0]);
glVertexAttribPointer(1, 4, GL_FLOAT, GL_FALSE, 16, &data[4]);
glDrawArrays(GL_POINTS, 0, 1);
will hit the interleaved path with an incorrect size (16 bytes instead
of 32 bytes). As a result, the data for attribute 1 never gets
uploaded. The single element draw case is the only sensible case I can
think of for non-interleaved-that-looks-like-interleaved data, but there
may be others as well.
To fix this, make sure that the end of the element in the array being
checked is within the stride "window." Previously the code would check
that the begining of the element was within the window.

vec4_visitor::generate_code() switches on vec4_instruction::opcode and
calls into the brw_eu_emit.c layer to generate code for some of them.
It then has a default case which calls generate_vec4_instruction() to
handle the rest...which switches on opcode and handles the rest of the
cases.
The split apparently is that generate_code() handles the actual hardware
opcodes (BRW_OPCODE_*) while generate_vec4_instruction() handles the
virtual opcodes (SHADER_OPCODE_* and VS_OPCODE_*). But this looks
fairly arbitrary, and it makes more sense to combine the two switches.
This patch moves the cases from generate_code() into the helper function
so that generate_code() isn't as large.

Commit 526ffdfc033ab01cf133cb7e8290c65d12ccc9be attempted to generalize
the source register type assertions to allow D and UD. However, the
src1 and src2 assertions actually checked src0.type against D and UD due
to a copy and paste bug.
It also began setting the source and destination register types based on
dest.type, ignoring src0/src1/src2.type completely. BFE and BFI2 may
actually pass mixed D/UD types and expect them to be ignored, which is
arguably a bit sloppy, but not too crazy either.
This patch simply removes the source register assertions as those values
aren't used anyway. It also clarifies the comment above the block that
sets the register types.

Over the last few years, the compiler has grown to support 7 different
language versions and 6 extensions that add new built-in types. With
more and more features being added, some of our core code has devolved
into an unmaintainable spaghetti of sorts.
A few problems with the old code:
1. Built-in types are declared...where exactly?
The types in builtin_types.h were organized in arrays by the language
version or extension they were introduced in. It's factored out to
avoid duplicates---every type only exists in one array. But that
means that sampler1D is declared in 110, sampler2D is in core types,
sampler3D is a unique global not in a list...and so on.
2. Spaghetti call-chains with weird parameters:
generate_300ES_types calls generate_130_types which calls
generate_120_types and generate_EXT_texture_array_types, which calls
generate_110_types, which calls generate_100ES_types...and more
Except that ES doesn't want 1D types, so we have a skip_1d parameter.
add_deprecated also falls into this category.
3. Missing type accessors.
Common types have convenience pointers (like glsl_type::vec4_type),
but others may not be accessible at all without a symbol table (for
example, sampler types).
4. Global variable declarations in a header file?
#include "builtin_types.h" in two C++ files would break the build.
The new code addresses these problems. All built-in types are declared
together in a single table, independent of when they were introduced.
The macro that declares a new built-in type also creates a convenience
pointer, so every type is available and it won't get out of sync.
The code to populate a symbol table with the appropriate types for a
particular language version and set of extensions is now a single
table-driven function. The table lists the type name and GL/ES versions
when it was introduced (similar to how the lexer handles reserved
words). A single loop adds types based on the language version.
Explicit extension checks then add additional types. If they were
already added based on the language version, glsl_symbol_table simply
ignores the request to add them a second time, meaning we don't need
to worry about duplicates and can simply list types where they belong.
v2: Mark uvecs and shadow samplers as ES3 only, and 1DArrayShadow as
unsupported in ES entirely. Add a touch more doxygen.

Currently, vector types are linked together closely: the glsl_type
objects for float, vec2, vec3, and vec4 are all elements of the same
array, in that exact order. This makes it possible to obtain vector
types via pointer arithmetic on the scalar type's convenience pointer.
For example, float_type + (3 - 1) = vec3.
However, relying on this is extremely fragile. There's no particular
reason the underlying type objects need to be stored in an array. They
could be individual class members, possibly with padding between them.
Then the pointer arithmetic would break, and we'd get bad pointers to
non-heap allocated data, causing subtle breakage that can't be detected
by valgrind. Cue insanity.
Or someone could simply reorder the type variables, causing us to get
the wrong type entirely. Also cue insanity.
Writing this explicitly is much safer. With the new helper functions,
it's a bit less code even.

This patch introduces new functions to quickly grab a pointer to a
vector type. For example:
glsl_type::bvec(4) returns glsl_type::bvec4_type
glsl_type::ivec(3) returns glsl_type::ivec3_type
glsl_type::uvec(2) returns glsl_type::uvec2_type
glsl_type::vec(1) returns glsl_type::float_type
This is less wordy than glsl_type::get_instance(GLSL_TYPE_BOOL, 4, 1),
which can help avoid extra word wrapping.

In glapi_priv.h we always need the typedef for the GLclampx type
since GL_OES_fixed_point is now defined in glext.h but the
GLclampx type is not. GLclampx is not used by anything in glext.h
but we need it for GL ES dispatch.
This is a huge patch because the structure of the file has been
changed.
The following extensions are new, however:
GL_AMD_interleaved_elements
GL_AMD_shader_trinary_minmax
GL_IBM_static_data
GL_INTEL_map_texture
GL_NV_compute_program5
GL_NV_deep_texture3D
GL_NV_draw_texture
GL_NV_shader_atomic_counters
GL_NV_shader_storage_buffer_object
GL_NVX_conditional_render
GL_OES_byte_coordinates
GL_OES_compressed_paletted_texture
GL_OES_fixed_point
GL_OES_query_matrix
GL_OES_single_precision
And these extensions were removed:
GL_FfdMaskSGIX
GL_INGR_palette_buffer
GL_INTEL_texture_scissor
GL_SGI_depth_pass_instrument
GL_SGIX_fog_scale
GL_SGIX_impact_pixel_texture
GL_SGIX_texture_select
