We are not aware of any GPU that actually implements the cross product
as a single instruction. Hence, there's no need for it to be an opcode.
Future commits will remove it entirely.

This is really supposed to be defined only if the driver supports highp
in the fragment shader - but all of our current ES2 implementations do.
So, just define it. In the future, we'll need to add a flag to
gl_context and only define the macro if the flag is set.
"Fixes" freedesktop.org bug #31673.

Return values were erroneously cast from (ir_rvalue*) to (ir_expression*).
NOTE: This is a candidate for the 7.9 branch.

ir_binop_less, ir_binop_greater, ir_binop_lequal, and ir_binop_gequal
are defined to work on vectors as well as scalars, as long as the two
operands have the same type.
This is evident from both ir_validate.cpp and our use of these opcodes
in the GLSL lessThan, greaterThan, lessThanEqual, greaterThanEqual
built-in functions.
Found by code inspection. Not known to fix any bugs. Presumably, our
tests for the built-in comparison functions must pass because C.E.
handling is done on the ir_call of "greaterThan" rather than the inlined
opcode. The C.E. handling of the built-in function calls is correct.
NOTE: This is a candidate for the 7.9 branch.

Default group bytes to 512 on evergreen. Don't query
tiling config yet for evergreen, the current info returned is not
adequate for evergreen (no way to get bank info).

Vertex data swizzles are already done in the vertex shader. Doing them twice
breaks BGRA vertex arrays for example.

RET was interpreted as END, which was wrong. Instead, if a shader contains RET
in the main function, it will fail to compile with an error message
from now on.
The hack is from early days.

These predicates will be used in other places soon.

This was accidentally removed in commit 32aaf89823de11e98cb59d5ec78c66cd3e74bcd4.

When drawing GL_DEPTH_COMPONENT the usual fragment pipeline steps apply
so don't override the depth state.
When drawing GL_STENCIL_INDEX (or GL_DEPTH_STENCIL) the fragment pipeline
does not apply (only the stencil and Z writemasks apply) so disable writes
to the color buffers.
Fixes some regressions from commit ef8bb7ada98f1ddc8e2554a7336af5d669cb1290

This helps distinguish between lowering passes, optimization passes, and
other compiler code.

This was from when glsl2 lived in a separate repository and used
automake.

This consolidates the TOKEN_OR_IDENTIFIER and RESERVED_WORD macros into
a single KEYWORD macro.
The old TOKEN_OR_IDENTIFIER macros handled the case of a word going from
an identifier to a keyword; the RESERVED_WORD macro handled a word going
from a reserved word to a language keyword. However, neither could
properly handle samplerBuffer (for example), which is an identifier in
1.10 and 1.20, a reserved word in 1.30, and a keyword in 1.40 and on.
Furthermore, the existing macros didn't properly handle reserved words
in GLSL ES 1.00. The best they could do was return a token (rather than
an identifier), resulting in an obtuse parser error, rather than a
user-friendly "you used a reserved word" error message.

This is nice because printing type->base_type in GDB will now give you a
readable name instead of a number.
|
|
Functions are not first class objects in GLSL, so there is never a value
of function type. No code actually used this except for one function
which asserted it shouldn't occur. One comment mentioned it, but was
incorrect. So we may as well remove it entirely.

The (piglit) mipmap_limits test shows the issue very clearly.

This driver is a fake swdri driver that perform no operations
beside allocation gallium structure and buffer for upper layer
usage.
It's purpose is to help profiling core mesa/gallium without
having pipe driver overhead hidding hot spot of core code.
scons file are likely inadequate i am unfamiliar with this
build system.
To use it simply rename is to swrast_dri.so and properly set
LIBGL_DRIVERS_PATH env variable.
