* glsl/lower_output_reads: fix geometry shader output handling with ↵Nicolai Hähnle2016-11-211-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | conditional emit Consider a geometry shader that contains code like this: some_out = expr; if (cond) { ... EmitVertex(); } else { ... EmitVertex(); } Both branches should see the correct value of some_out. Since this is a rather subtle and rare case, I'm submitting a piglit test for this as well. GLSL says that the values of output variables are undefined after EmitVertex(). With this change, the values will now be defined and unmodified. This may reduce optimization opportunities in the probably quite rare case where subsequent compiler passes cannot prove that the value of the output variable is overwritten.

| | | | | | | | | | | | | | | | | | | | | | | | | | Karol Herbst's fuzzing efforts discovered that we would hit the following assert: assert(dummy_instructions.is_empty()); when processing an illegal array size expression of float[(1=1)?1:1] t; In do_assignment, we realized we needed an rvalue for (1 = 1), and generated a temporary variable and assignment from the RHS. We've already flagged an error (non-lvalue in assignment), and return a bogus value as the rvalue. But process_array_size sees the bogus value, which happened to be a constant expression, and rightly assumes that processing a constant expression shouldn't have generated any code. instructions. To handle this, make do_assignment not generate any temps or assignments when it's already raised an error - just return an error value directly.

| | | | | | | | | | | | | | | | | | | | | | If the user did not request full linking, link the shader with the built-in functions, inline them, and eliminate them.

Update expected output of warnings tests to prevent 'make check' regressions. v4: Optimize harder. Most important, do function inlining.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The #version directive can only handle decimal constants. Enforce that the value is a decimal constant. Section 3.3 (Preprocessor) of the GLSL 4.50 spec says: The language version a shader is written to is specified by #version number profile opt where number must be a version of the language, following the same convention as __VERSION__ above. The same section also says: __VERSION__ will substitute a decimal integer reflecting the version number of the OpenGL shading language. Use a separate flag to track whether or not the #version line has been encountered. Any possible sentinel (0 is currently used) could be specified in a #version directive. This would lead to trying to (internally) redefine __VERSION__. Since there is no parser location for this addition, NULL is passed. This eventually results in a NULL dereference and a segfault. Attempts to use -1 as the sentinel would also fail if '#version 4294967295' or '#version 18446744073709551615' were used. We should have piglit tests for both of these.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now were validating in/out blocks by listing the inputs in the consumer stage and then, for each output of the producer, we checked that it was a match if it was consumed. This method does not catch the case where the consumer has an input that is not present as an output in the producer stage, because it only generates link errors for outputs present in the producer stage that don't match the inputs in the consumer stage. The current method does catch the case were an output from the producer stage is not consumed, which is irrelevant and is ignored. By reversing the way we do this, we can detect this situation, so this patch lists the outputs of the producer stage and then validates inputs of the consumer stage against them. If we see an input in the consumer for which there is no associated output in the producer, we produce a link error. The only exception to this is the special built-in input block gl_in[], since this is implicitly generated for geometry and tessellation stages, but we don't generate it if the producer stage does not write to any of the pre-defined outputs (for example, if the vertex shader does not write to gl_Position, etc). Since writing to these is not mandatory, do not produce a link error in that case. There is a CTS tessellation test (GL45-CTS.tessellation_shader.program_object_properties) that has an empty vertex shader (so it does not produce gl_in[]) and would fail to link if we don't do this.
