The ir_constant::has_value method already does this.

This is an invasive set of changes. Each user shader tracks a set of other
shaders that contain built-in functions. During compilation, function
prototypes are imported from these shaders. During linking, the
shaders are linked with these built-in-function shaders just like with
any other shader.

And remove checks of surface depth bits. The state tracker should
not turn on depth/stencil testing if the framebuffer doesn't have
depth/stencil.

glx_info is used if X_DRI2SwapBuffers is defined

This configure some of the value properly based on
asic so others asic than RV710 works too.

some of the ALU instructions are different on r6xx vs r7xx,
separate the alu translation to separate files, and use family
to pick which compile stage to use.
|
|
allow pipe driver to get the family of the gpu.
|
|
The other drivers just return 0 without the assert.
|
|
Depth clamping seems to be implicit if clipping is disabled.
It's not perfect, but it's good enough for wine and passes
the corresponding piglit tests.

To quiet a compiler warning.
|
|
In both the preprocessor and in the compiler proper, we use a custom
yyltype struct to allow tracking the source-string number in addition
to line and column. However, we were previously relying on bison's
default initialization of the yyltype struct which of course is not
aware of the source field and leaves it uninitialized.
We fix this by defining our own YYLLOC_DEFAULT macro expanding on the
default version (as appears in the bison manual) and adding
initialization of yylloc.source.
|
|
This quiets a compiler warning, (and ensures a segmentation fault rather
than memory corruption if this variable is written through before being
initialized elsewhere).
|
|
While bootstrapping the dependencies, make will see the "include depend"
directive before the depend file has been created. To avoid a spurious
warning in this case we use "-include" instead, (which differs precisely
in the fact that it will not emit a diagnostic if the named file does
not exist).

Based on the two recent changes to program_lexer.l.
|
|
This avoids two "function defined but not used" warnings. For the yyinput
function we define YY_NO_INPUT which tells flex to simply not generate this
function.
For unput, we add a call to this function, but inside a while(0) so
that it will quiet the warning without actually changing any
functionality.
|
|
Add declarations for two functions generated in the flex ouput. It
would be nicer if flex simply declared these generated functions as
static, but for now we can at least avoid the warning this way.
|
|
Previously, any occurence of the unary plus operator would trigger a
bogus type mismatch error. Fix this by making the ast_plus case look
more like the ast_neg case as far as type-checking is concerned.
With this change the shaders/CorrectPreprocess8.frag test in piglit
now passes.
|
|
Set sampler max_lod to avoid sampling the 1x1 and 2x2 mipmap levels.
Fixes piglit line-aa-width test, fd.o bug 29160.

Instead of one big boolean indicating indirect addressing, use a
bitfield indicating which register files are accessed with indirect
addressing.
Most shaders that use indirect addressing only use it to access the
constant buffer. So no need to use an array for temporary registers
in this case.

As with indexing the const buffer, the ADDR reg may have totally
different values for each element. Need to use a gather operation.
|
|
|
|
|
|
This used to be a somewhat packed struct, but no longer. Remove the
last remaining bitfield tag.
|
|
|
|
The previous code assumed that all elements of the address register
were the same. But it can vary from pixel to pixel or vertex to
vertex so we must use a gather operation when dynamically indexing
the constant buffer.
Still need to fix this for the temporary register file...

The lowering code should probably be moved elsewhere.

Coming changes to the handling of built-in functions necessitate this.
|
|
This is quite a large patch because breaking it into smaller pieces
would result in the tree being intermitently broken. The big changes
are:
* Add the ir_var_temporary variable mode
* Change the ir_variable constructor to take the mode as a
parameter and correctly specify the mode for all ir_varables.
* Change the linker to not cross validate ir_var_temporary
variables.
* Change the linker to pull all ir_var_temporary variables from
global scope into 'main'.

This caught the failure in cloning of ir_dereference_record.
|
|
We're good at propagating error types around, but finding when the
first one was triggered can be painful if we aren't paying attention.
