* mesa: Move transform feedback error check to reduce array overflow risk.Paul Berry2012-01-111-20/+32
| | | | | | | | | | | | | | | | | | | | | | | | | Previous to this patch, we didn't do the limit check for MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS until the end of the store_tfeedback_info() function, *after* storing all of the transform feedback info in the gl_transform_feedback_info::Outputs array. This meant that the limit check wouldn't prevent us from overflowing the array and corrupting memory. This patch moves the limit check to the top of tfeedback_decl::store() so that there is no risk of overflowing the array. It also adds assertions to verify that the checks for MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS and MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS are sufficient to avoid array overflow. Note: strictly speaking this patch isn't necessary, since the maximum possible number of varyings is MAX_VARYING (16), whereas the size of the Outputs array is MAX_PROGRAM_OUTPUTS (64), so it's impossible to have enough varyings to overflow the array. However it seems prudent to do the limit check before the array access in case these limits change in the future. Reviewed-by: Ian Romanick <[email protected]>
* mesa: Fix transform feedback of unsubscripted gl_ClipDistance array.Paul Berry2012-01-111-33/+56
| | | | | | | | | | | | | | | | | | | | | On drivers that set gl_shader_compiler_options::LowerClipDistance (for example i965), we need to handle transform feedback of gl_ClipDistance specially, to account for the fact that the hardware represents it as an array of vec4's rather than an array of floats. The previous way this was accounted for (translating the request for gl_ClipDistance[n] to a request for a component of gl_ClipDistanceMESA[n/4]) doesn't work when performing transform feedback on the whole unsubscripted array, because we need to keep track of the size of the gl_ClipDistance array prior to the lowering pass. So I replaced it with a boolean is_clip_distance_mesa, which switches on the special logic that is needed to handle the lowered version of gl_ClipDistance.

* mesa: Fix computation of transform feedback num_components.Paul Berry2012-01-111-1/+7
| | | | | | | | | | | | | | | | | | The function tfeedback_decl::num_components() was not correctly accounting for transform feedback of whole arrays and gl_ClipDistance. The bug was hard to notice in tests, because it only affected the checks for MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS and MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS. This patch fixes the computation, and adds an assertion to verify num_components() even when MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS and MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS are not exceeded. The assertion requires keeping track of components_so_far in tfeedback_decl::store(); this will be useful in a future patch to fix non-multiple-of-4-sized gl_ClipDistance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The trick was to produce an assignment in the IR along the lines of: (assign (xyzw) (var_ref R0) (swiz wwww (var_ref R0) )) which occurs only rarely even in code that looks like it should do this, because of the assignment temporaries generated in ast_to_hir. From the IR above, this optimization pass would then propagate references of R0 into R0.wwww (seems reasonable), but without this patch, a later reference of R0.wwww would see R0 first, turning that into R0.wwww.wwww, which triggered opt_swizzle_swizzle, and then we looped back to this code to do it again. Avoid that by skipping over the usual ir_rvalue visitor's ir_swizzle hook, so that we get handle_rvalue() on the ir_swizzle itself, not its referenced value. Looking at only the swizzle will always optimize away at least as much as looking at the swizzle's refererenced value. We now still claim to propagate r0.w into r0.w, but at least we don't trigger the loop. v2: Rewrite commit message (changes by anholt) Fixes piglit glsl-copy-propagation-self-1 Fixes https://bugs.freedesktop.org/show_bug.cgi?id=34006

* mesa: Fix transform feedback of unsubscripted arrays.Paul Berry2012-01-051-45/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is not explicitly stated in the GL 3.0 spec that transform feedback can be performed on a whole varying array (without supplying a subscript). However, it seems clear from context that this was the intent. Section 2.15 (TransformFeedback) says this: When writing varying variables that are arrays, individual array elements are written in order. And section 2.20.3 (Shader Variables), says this, in the description of GetTransformFeedbackVarying: For the selected varying variable, its type is returned into type. The size of the varying is returned into size. The value in size is in units of the type returned in type. If it were not possible to perform transform feedback on an unsubscripted array, the returned size would always be 1. This patch fixes the linker so that transform feedback on an unsubscripted array is supported. Fixes piglit tests "EXT_transform_feedback/builtin-varyings gl_ClipDistance[{4,8}]-no-subscript" and "EXT_transform_feedback/output_type *[2]-no-subscript". Note: on back-ends that set gl_shader_compiler_options::LowerClipDistance (for example i965), tests "EXT_transform_feedback/builtin-varyings gl_ClipDistance[{1,2,3,5,6,7}]" still fail.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using transform feedback, there are three circumstances in which it is useful for Mesa to instruct a driver to stream out just a portion of a varying slot (rather than the whole vec4): (a) When a varying is smaller than a vec4, Mesa needs to instruct the driver to stream out just the first one, two, or three components of the varying slot. (b) In the future, when we implement varying packing, some varyings will be offset within the vec4, so Mesa will have to instruct the driver to stream out an arbitrary contiguous subset of the components of the varying slot (e.g. .yzw or .yz). (c) On drivers that set gl_shader_compiler_options::LowerClipDistance, if the client requests that an element of gl_ClipDistance be streamed out using transform feedback, Mesa will have to instruct the driver to stream out a single component of one of the gl_ClipDistance varying slots. Previous to this patch, only (a) was possible, since gl_transform_feedback_info specified only the number of components of the varying slot to stream out. This patch adds gl_transform_feedback_info::ComponentOffset, which indicates which components should be streamed out. Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | This patch adds two new fields to the gl_transform_feedback_info struct: - BufferStride records the total number of components (per vertex) that transform feedback is being instructed to store in each buffer. - Outputs[i].DstOffset records the offset within the interleaved structure of each transform feedback output. These values are needed by the i965 gen6 and r600g back-ends, so it seems better to have the linker provide them rather than force each back-end to compute them independently. Also, DstOffset helps pave the way for supporting ARB_transform_feedback3, which allows the transform feedback output to contain holes between attributes by specifying gl_SkipComponents{1,2,3,4} as the varying name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Invalid shaders containing the character % at an unexpected location would cause Bison to call yyerror with a message of: syntax error, unexpected '%' Bison expects yyerror() to take a string, while _mesa_glsl_error() is a printf-style function. This hit the classic printf string escape issue: _mesa_glsl_error(loc, state, "unexpected '%'"); // invalid! _mesa_glsl_error(loc, state, "%s", "unexpected '%'"); // correct. This caused assertion failures after ralloc_asprintf_append called vsnprintf to determine the length of the text that would be printed: vsnprintf would see the invalid format and return -1, an invalid length. The solution is to define a proper yyerror() wrapper function that calls _mesa_glsl_error with the "%s". Since we compile with -p "_mesa_glsl", yyerror is defined as: #define yyerror _mesa_glsl_error So we have to #undef yyerror in order to be able to declare it.

The second call, abs(5), would find the newly imported float signature in the local shader, and settle for that.

Not to mention printing a user-friendly error message with pretty-printed "maybe you meant this" candidate signatures. The second has to deal with void/non-void functions, pre-call implicit conversions for "in" parmeters, and post-call "out" call conversions. Trying to do both in one function is just too unwieldy.

This could be done via the existing mechanisms: sig = f->exact_matching_signature(params); if (sig != NULL) { exact = true; } else { sig = f->matching_signature(params); exact = false; } However, this requires walking the list of function signatures twice, which also means walking each signature's formal parameter lists twice.
