Kenneth Graunke 67029b13b7 Actually emit temp declaration in vector comparison builtins. 2010-04-21 23:58:13 -07:00
Kenneth Graunke 6202cbfe36 Fix ir_dead_code for function refactoring. 2010-04-21 16:02:15 -07:00
Kenneth Graunke 7bcd5bedcc Emit body for constructors in the right place. 
Previously, the body of some vector constructors were added to the wrong
function signature, and the body of matrix constructors were just being
dumped in the main instruction stream.
 2010-04-21 15:37:10 -07:00
Kenneth Graunke 3289886688 Remove ir_label since it is no longer used. 2010-04-21 15:37:10 -07:00
Kenneth Graunke 9fa99f3b6c Refactor IR function representation. 
Now, ir_function is emitted as part of the IR instructions, rather than
simply existing in the symbol table.  Individual ir_function_signatures
are not emitted themselves, but only as part of ir_function.
 2010-04-21 15:36:36 -07:00
Kenneth Graunke f96c52ba2e Use ir_function_signature::function_name() rather than direct access. 2010-04-21 15:36:36 -07:00
Kenneth Graunke 67a092ae09 Ensure that both parameter lists are the same length in function overloading. 
Fixes new test function-05.glsl, where the second function has matching
parameter types, but less of them.

Ian Romanick ff236fa9b6 Add missing break statement 2010-04-21 15:08:08 -07:00
Eric Anholt 7d21104a8b Remove dead code assignments and variable declarations. 
This pass only works on assignments where the variable is never
referenced.  There is no code flow analysis, so it can't do a better
job of avoiding redundant assignments.

For now, the optimizer only does do_dead_code_unlinked(), so it won't
trim the builtin variable list or initializers outside of the scope of
functions.  This is because we don't have the visibility into other
functions that might get linked in in order to eliminate work on
global variables.

Eric Anholt 71df19f5ef Mark some variables as having usage beyond the shader's scope. 
This will be important to optimization passes.  We don't want to
dead-code eliminate writes to out varyings, or propagate uninitialized
values of uniforms.

Ian Romanick 484606610e While-loops also start a new scope. 2010-04-16 16:42:43 -07:00
Eric Anholt 44b694e1f6 Avoid generating ir_if for &&, || short-circuiting with constant LHS. 
It was breaking constant expression detection for constant
initializers, i.e. CorrectParse2.frag, CorrectParse2.vert.
 2010-04-16 13:49:04 -07:00
Eric Anholt 0d42321ec1 Add support for inlining calls done inside of expressions. 2010-04-16 12:56:18 -07:00
Eric Anholt 4950a68bf2 Make && and || only evaluate the RHS when the LHS requires it. 2010-04-16 01:10:32 -07:00
Eric Anholt 5ba9420608 Add an ir_if simplification pass. 
This is relatively simple at the moment, recognizing only constant
values, and not (for example) values that are restricted to a range
that make the branching constant.  However, it does remove 59 lines
from the printout of CorrectParse2.vert.
 2010-04-14 17:05:13 -07:00
Eric Anholt 60be7626b8 Check that the return type of function definition matches its prototype. 
Doesn't fix any testcases, but fixes a FINISHME.
 2010-04-14 16:19:19 -07:00
Eric Anholt 1e7ec3ce12 Check that function definition parameter qualifiers match proto qualifiers. 
Fixes function9.frag.
 2010-04-14 16:18:19 -07:00

Fixes CorrectFunction1.vert, glsl-fs-notequal.frag.
 2010-04-08 15:35:34 -07:00
Eric Anholt cc49cea9ea Add support for builtin gentype mix(gentype a, gentype b) 
Fixes glsl-fs-mix.frag, glsl-fs-mix-constant.frag.
 2010-04-08 15:10:37 -07:00

Eric Anholt 925759283a Add builtin normalize() functions. 
Fixes CorrectSqizzle2.vert.
 2010-04-08 14:38:32 -07:00
Eric Anholt 2a7b2b22f4 Repeat the optimization passes until we stop making progress. 2010-04-08 13:43:56 -07:00
Eric Anholt 6192434ac3 Add inlining support for array dereferences. 2010-04-08 13:42:41 -07:00
Eric Anholt cad9766118 Inline functions consisting of a return of an expression. 2010-04-08 11:24:06 -07:00
Ian Romanick b427c917ce Remove extraneous base-class constructor calls 2010-04-07 18:03:50 -07:00
Eric Anholt fbc7c0b8f2 Make function bodies rely on the parameter variable declarations. 
Previously, generating inlined function bodies was going to be
difficult, as there was no mapping between the body's declaration of
variables where parameter values were supposed to live and the
parameter variables that a caller would use in paramater setup.
Presumably this also have been a problem for actual codegen.
 2010-04-07 17:23:23 -07:00
Eric Anholt 6173312d84 Make dot() take the right number of args. 2010-04-07 17:23:23 -07:00
Eric Anholt 7e78e07ddb Fix the returns of builtin functions to actually return. 2010-04-07 17:23:23 -07:00
Eric Anholt 894ea972a4 Put function bodies under function signatures, instead of flat in the parent. 
This will let us know the length of function bodies for the purpose of
inlining (among other uses).

Eric Anholt f1ddca9f21 Clarify the types of various exec_list in ir.h 2010-04-07 17:23:23 -07:00

Ian Romanick 887a8b07de Clean up error reporting in _mesa_glsl_process_extension 2010-04-07 16:57:56 -07:00
Ian Romanick c178c74c27 Add tracking for extension based warnings 
Using '#extension foo: warn' instructs the compiler to generate a
warning when some feature of the extension 'foo' is used.  This patch
adds some infrastructure needed to support that for variables.

Similar changes will be needed for types and built-in functions.

Ian Romanick 1799a0cd41 Emit a warning when an unknown extension is used with #extension 2010-04-07 16:49:25 -07:00
Ian Romanick 56b8b21410 Add _mesa_glsl_warning to emit warnings to the shader log 2010-04-07 16:49:25 -07:00
Ian Romanick e701761cc8 Begin processing #extension directive 
Nowhere near complete.  It just parses correctly at this point.
 2010-04-07 16:49:25 -07:00
Ian Romanick ae4c4c0795 Use _mesa_glsl_shader_target_name 2010-04-07 16:49:25 -07:00
Ian Romanick 5bfe30a02b Add utility function to get the name of a shader target 2010-04-07 16:49:25 -07:00
Ian Romanick 1b3f47fd36 Call glsl_type::get_instance correctly: the number of rows must be at least 1 
This causes the following tests to pass:

    shaders/glsl-tex-mvp.vert

Ian Romanick b0b8fa4885 Eat whitespace while in the PP state 2010-04-07 16:49:25 -07:00
Ian Romanick 62f62ca3b3 Partially fix comment handling in preprocessor directives. 
Multi-line /* */ comments are still broken.  I think this will wait to
be fixed until we have a real preprocessor.
 2010-04-07 16:49:25 -07:00
Ian Romanick 77cce649c9 Add support for bool to ir_equal and ir_nequal constant handling 2010-04-07 16:49:25 -07:00
Ian Romanick 8645a955fc Add gl_ClipDistance in fragment shader 2010-04-07 16:49:25 -07:00
Ian Romanick 8c46ed2490 Generate correct IR for do-while loops 
Previously the same code was generated for a while loop and a do-while
loop.  This pulls the code that generates the conditional break into a
separate method.  This method is called either at the beginning or the
end depending on the loop type.

Ian Romanick 4cf20cd37c Process ast_jump_statement into ir_loop_jump 
Specifically, handle 'break' and 'continue' inside loops.

This causes the following tests to pass:

    glslparsertest/shaders/break.frag
    glslparsertest/shaders/continue.frag
