Eric Anholt a9fafc6504 Don't let swizzles with duplicated components be considered as lvalues. 
Fixes swizzle2.frag.
 2010-03-29 12:48:45 -07:00
Eric Anholt ab372dab2a Reject main() declarations with a non-void return value. 
Fixes main3.vert.
 2010-03-29 12:48:45 -07:00
Eric Anholt 2e063f1adf Reject variables marked with attribute in the fragment shader. 
Fixes attribute.frag.
 2010-03-29 12:48:45 -07:00
Eric Anholt 3cb4358f38 Add the instruction for the parameter variable declarations of builtin funcs. 
Matches constructor setup, but I'm not really sure why we make the
variable twice.

Eric Anholt 76a91e1afb Implement dot() builtin. 2010-03-29 12:48:45 -07:00
Eric Anholt 01665262e5 Implement exp2() and log2(), and make ir_unop_exp and ir_unop_log be base e. 
Making the base e functions IR operations is not a clear win.  i965
doesn't support it, it doesn't look like r600 supports it, but r500
does. It should be easily supportable as a lowering pass, though.

Eric Anholt 53afc3609d Implement builtin length() function. 2010-03-29 12:48:45 -07:00
Eric Anholt 44d68fd06f Add sqrt() builtin as an IR operation. 
Following a discussion in #dri-devel, I think this makes more sense
than implementing it as RSQ RCP CMP as Mesa did.  The i965 has a
hardware sqrt that should work, and AMD is suppposed to be able to
implement it as RSQ RCP with an alternate floating point mode so that
the 0.0 case is handled like we want.

Eric Anholt ddd2e83db2 Add builtin pow() function. 2010-03-29 12:48:45 -07:00
Eric Anholt 0f09aea3bf Add support for builtin deprecated fs varyings. 
Fixes glsl-color.frag.

Eric Anholt bfe380a721 Implement some binary gentype builtin functions. 2010-03-29 12:48:45 -07:00
Eric Anholt 2eec73f735 Implement additional unary gentype builtins. 2010-03-29 12:48:45 -07:00
Eric Anholt c22c40015d Implement the first builtin function: exp(). 2010-03-29 12:48:45 -07:00
Ian Romanick 43de172820 Generate more correctly diagnostics from some invalid initializers 2010-03-28 17:03:16 -07:00
Ian Romanick 66faec4895 Initial bits to process initializers in variable declarations 
As a result, the following tests pass:

    glslparsertest/array3.frag
    glslparsertest/CGStandardLibrary.frag
    glslparsertest/ConstantConversions.frag
    glslparsertest/constructor1.frag
    glslparsertest/constructor2.frag
    glslparsertest/constructor3.V110.frag
    glslparsertest/dataType4.frag
    glslparsertest/dataType5.frag
    glslparsertest/dataType13.frag
    glslparsertest/dataType19.frag
    glslparsertest/matrix.V110.frag
    glslparsertest/parser7.frag
    glslparsertest/swizzle3.frag

The following tests also pass, but it is just by dumb luck.  In these
cases the shader fails to compile, but it fails for the wrong reason:

    glslparsertest/array6.frag
    glslparsertest/comma2.frag
    glslparsertest/conditional1.frag
    glslparsertest/conditional2.frag
    glslparsertest/conditional3.frag
    glslparsertest/constFunc.frag
    glslparsertest/ParseTest3.frag
    glslparsertest/ParseTest4.frag
    glslparsertest/varying3.frag
    glslparsertest/parser8.frag (also segfaults)
    glslparsertest/parser9.frag (also segfaults)

The following tests now fail.  As far as I can tell, these are all
cases where the shader was failing to compile, but it was failing for
the wrong reason.

    glslparsertest/CorrectMatComma.frag
    glslparsertest/CorrectModule.frag
    glslparsertest/CorrectSwizzle2.vert
    glslparsertest/shaders/glsl-fs-bug25902.frag

Ian Romanick 19360152f5 Reject uniform initializers in GLSL 1.10 mode 
Now both glslparsertest/dataType3.frag and glslparsertest/dataType2.frag pass.

Eric Anholt 72fc47f0b0 Set variables with the sampler base type to read only. 
Fixes increment3.frag.

Eric Anholt 8518e75d28 Set the var_type for arrays to error_type until it's implemented. 
"Fixes" segfaults in array tests.

Eric Anholt 76ea56c007 Add support for ast_to_hir of pre inc/dec. 2010-03-26 17:51:41 -07:00
Eric Anholt de38f0ed53 Add support for ast_to_hir of post inc/dec. 2010-03-26 17:51:41 -07:00
Eric Anholt c4f86d3b80 Make read-only variables not be considered lvalues. 
This should fix tests trying to assign to builtin "in" variables, and
will also be relied on for post_inc/dec handling.
 2010-03-26 17:51:41 -07:00
Eric Anholt 3c36b2df7c Add constructors for immediate hir constants. 
This will make ast_to_hir for inc/dec easier.
 2010-03-26 17:51:41 -07:00
Eric Anholt 48a0e64b7d Add support for %= in ast_to_hir. 2010-03-26 17:51:41 -07:00

Ian Romanick d1dfe8b994 IR print visitor: Print expressions a little better 2010-03-26 17:42:10 -07:00
Ian Romanick 0b7dcc80eb Initial implementation of constructor handling code 
All of the scalar, vector, and matrix constructors *except* "from
bool" constructors should be handled.  Array and structure
constructors are also not yet handled.

Ian Romanick 605ff69b0d Add missing parenthesis in foreach_iter 
This allows uses like 'foreach_iter(exec_list_iterator, iter, *list_ptr)'.

Ian Romanick 738c183cc9 Slightly change the representation of numeric types 
For numeric types, vector_elements and matrix_columns must be at least
1.  Previously matrix_columns was 0 for vectors, and both were 0 for
scalars.  This change simplifies things in some places.
 2010-03-26 14:43:16 -07:00

Ian Romanick a43817a483 Use glsl_type::is_error instead of comparison with glsl_error_type pointer 2010-03-26 14:27:23 -07:00
Kenneth Graunke affc1413ac Move swizzles out of ir_dereference and into their own class. 
Also turn generate_swizzle into a static "create" method of the new
class; we'll want to use it for the IR reader as well.

Kenneth Graunke 44e1dfa2df Replace "mode" type tag with virtual as_foo() downcasting functions. 
These should work well even in a non-flat IR hierarchy.

This makes it a lot easier to read... if you have a really wide display.

Ian Romanick d7388f389d IR print visitor: print expressions 
Not quite complete.  The operator is not yet printed.

Ian Romanick 8c70a62193 IR print visitor: print ir_dereference instructions 
Also make a slight change to ir_variable.  The ir_dereference tracks
the number of nested dereferences.  If an ir_variable is visited and
the count is non-zero, just print the name of the variable.
