* glsl: empty declarations should be validChia-I Wu2011-08-052-12/+8
| | | | | | | | | | | | | | | Unlike C++, empty declarations such as float; should be valid. The spec is not explicit about this actually. Some apps that generate their shader sources may rely on this. This was noted when porting one of them to Linux from Windows.

* mesa: Ensure that gl_shader_program::InfoLog is never NULLIan Romanick2011-08-021-0/+1
| | | | | | | | | | | | | | | | This prevents assertion failures in ralloc_strcat. The ralloc_free in _mesa_free_shader_program_data can be omitted because freeing the gl_shader_program in _mesa_delete_shader_program will take care of this automatically. A bunch of this code could use a refactor to use ralloc a bit more effectively. A bunch of the things that are allocated with malloc and owned by the gl_shader_program should be allocated with ralloc (using the gl_shader_program as the context).

* glsl: improve the accuracy of the atan(x,y) builtin function.Paul Berry2011-08-011-1/+3
| | | | | | | | | | The previous formula for atan(x,y) returned a value of +/- pi whenever |x|<0.0001, and used a formula based on atan(y/x) otherwise. This broke in cases where both x and y were small (e.g. atan(1e-5, 1e-5)). This patch modifies the formula so that it returns a value of +/- pi whenever |x|<1e-8*|y|, and uses the formula based on atan(y/x) otherwise.
* glsl: improve the accuracy of the asin() builtin function.Paul Berry2011-08-011-28/+40
| | | | | | | | | | | | | | | | | | | | | | | | The previous formula for asin(x) was algebraically equivalent to: sign(x)*(pi/2 - sqrt(1-|x|)*(A + B|x| + C|x|^2)) where A, B, and C were arbitrary constants determined by a curve fit. This formula had a worst case absolute error of 0.00448, an unbounded worst case relative error, and a discontinuity near x=0. Changed the formula to: sign(x)*(pi/2 - sqrt(1-|x|)*(pi/2 + (pi/4-1)|x| + A|x|^2 + B|x|^3)) where A and B are arbitrary constants determined by a curve fit. This has a worst case absolute error of 0.00039, a worst case relative error of 0.000405, and no discontinuities. I don't expect a significant performance degradation, since the extra multiply-accumulate should be fast compared to the sqrt() computation. Fixes piglit tests {vs,fs}-asin-float and {vs,fs}-atan-*

* glsl: Fix conversions in array constructorsChad Versace2011-07-301-2/+10
| | | | | | | | | | | | | | | | | | | | | | Array constructors obey narrower conversion rules than other constructors [1] --- they use the implicit conversion rules [2] instead of the scalar constructor conversions [3]. But process_array_constructor() was incorrectly applying the broader rules.

| | | | | | | | | | | | | | | | | | | | lower_variable_index_to_cond_assign runs until it can't make any more progress. It then returns the result of the last pass which will always be false. This caused the lowering loop in _mesa_ir_link_shader to end before doing one last round of lower_if_to_cond_assign. This caused several if-statements (resulting from lower_variable_index_to_cond_assign) to be left in the IR. In addition to this change, lower_variable_index_to_cond_assign should take a flag indicating whether or not it should even generate if-statements. This is easily controlled by switch_generator::linear_sequence_max_length. This would generate much better code on architectures without any flow contol.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the code would just look at deref->array->type to see if it was a constant. This isn't good enough because deref->array might be another ir_dereference_array... of a constant. As a result, deref->array->type wouldn't be a constant, but deref->variable_referenced() would return NULL. The unchecked NULL pointer would shortly lead to a segfault. Instead just look at the return of deref->variable_referenced(). If it's NULL, assume that either a constant or some other form of anonymous temporary storage is being dereferenced. This is a bit hinkey because most drivers treat constant arrays as uniforms, but the lowering pass treats them as temporaries. This keeps the behavior of the old code, so this change isn't making things worse.

| | | | | | | | | | | | | | | | | | | | | | | | | The previous implementation could easily get tricked if the LHS of an assignment included a non-constant index that was "inside" another dereference. For example: mat4 m[2]; m[0][i] = vec4(0.0); Due to the way it tracked whether the array was being assigned, it would think that the non-constant index was in an r-value. The new code fixes that by tracking l-values and r-values differently. The index is also replaced by cloning the IR and replacing the index variable instead of the odd way it was done before. v2: Apply some simplifications suggested by Eric Anholt. Making assignment_generator::rvalue be ir_dereference instead of ir_rvalue simplified the code a bit. Fixes i965 piglit fs-temp-array-mat[234]-index-wr and vs-varying-array-mat[234]-index-wr.

| | | | | | | | | | | | | This patch adds a new build artifact, glsl_test, which can be used for testing optimization passes in isolation. I'm hoping that we will be able to add other useful standalone tests to this executable in the future. Accordingly, it is built in a modular fashion: the main() function uses its first argument to determine which test function to invoke, removes that argument from argv[], and then calls that function to interpret the rest of the command line arguments and perform the test. Currently the only test function is "optpass", which tests optimization passes.

The complie-time check happens to detect some cases that may be removed by various optimization passes. The spec doesn't seem to allow this, but other vendors (e.g., NVIDIA) appear to only check at link-time after all optimizations.

| | | | | | | | | | | | | | | | | | | | | When parsing S-Expressions, we need to store nul-terminated strings for Symbol nodes. Prior to this patch, we called ralloc_strndup each time we constructed a new s_symbol. It turns out that this is obscenely expensive. Instead, copy the whole buffer before parsing and overwrite it to contain \0 bytes at the appropriate locations. Since atoms are separated by whitespace, (), or ;, we can safely overwrite the character after a Symbol. While much of the buffer may be unused, copying the whole buffer is simple and guaranteed to provide enough space. Prior to this, running piglit-run.py -t glsl tests/quick.tests with GLSL 1.30 enabled took just over 10 minutes on my machine. Now it takes 5.

| | | | | | | | | | | | | | | | | | | | | | This brings us into compliance with page 17 (page 22 of the PDF) of the GLSL 1.20 spec: "[Sampler types] can only be declared as function parameters or uniform variables (see Section 4.3.5 "Uniform"). ... [Samplers] cannot be used as out or inout function parameters." The spec isn't explicit about whether this rule applies to structs/arrays containing shaders, but the intent seems to be to ensure that it can always be determined at compile time which sampler is being used in each texture lookup. So to avoid creating a loophole, the rule needs to apply to structs/arrays containing shaders as well. Fixes piglit tests spec/glsl-1.10/compiler/samplers/*.frag, and fixes bug 38987.

* linker: Only over-ride built-ins when a prototype has been seenIan Romanick2011-07-172-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | The GLSL spec says: "If a built-in function is redeclared in a shader (i.e., a prototype is visible) before a call to it, then the linker will only attempt to resolve that call within the set of shaders that are linked with it." This patch enforces this behavior. When a function call is processed a flag is set in the ir_call to indicate whether the previously seen prototype is the built-in or not. At link time a call will only bind to an instance of a function that matches the "want built-in" setting in the ir_call. This has the odd side effect that first call to abs() in the shader below will call the built-in and the second will not: float foo(float x) { return abs(x); } float abs(float x) { return -x; } float bar(float x) { return abs(x); } This seems insane, but it matches what the spec says.
