* glsl: Properly pack GS output varyingsPaul Berry2013-08-011-2/+57
| | | | | | | | | | | | | | In geometry shaders, outputs are consumed at the time of a call to EmitVertex() (as opposed to all other shader types, where outputs are consumed when the shader exits). Therefore, when packing geometry shader output varyings using lower_packed_varyings, we need to do the packing at the time of the EmitVertex() call. This patch accomplishes that by adding a new visitor class, lower_packed_varyings_gs_splicer, which is responsible for splicing the varying packing code into place wherever EmitVertex() is found.

* glsl: Modify varying packing to use a temporary exec_list.Paul Berry2013-08-011-10/+18
| | | | | | | | | | | | | | This patch modifies lower_packed_varyings to store the packing code it generates in a temporary exec_list, and then splice that list into the shader's main() function when it's done. This paves the way for supporting geometry shader outputs, where we'll have to splice a clone of the packing code before every call to EmitVertex(). As a side benefit, varying packing code is now emitted in the same order for inputs and outputs; this should make debug output a little easier to read. Reviewed-by: Ian Romanick <[email protected]>

| | | | | | | | | | | | | | | | From section 4.3.4 (Inputs) of the GLSL 1.50 spec: Geometry shader input variables get the per-vertex values written out by vertex shader output variables of the same names. Since a geometry shader operates on a set of vertices, each input varying variable (or input block, see interface blocks below) needs to be declared as an array. Therefore, the element type of each geometry shader input array should match the type of the corresponding vertex shader output.

* main: Allow for the possibility of GL 3.2 without ARB_geometry_shader4.Paul Berry2013-08-017-8/+17
| | | | | | | | | | | | | | | | | | | | | | Previously, we assumed that the only way Mesa would expose geometry shader support was via the ARB_geometry_shader4 extension. But this extension has some extra complications over GL 3.2 (interactions with compatibility-only features, and link-time initialization of the constant gl_VerticesIn). So we want to allow for the possibility of supporting GL 3.2 (with GLSL 1.50 style geometry shaders) even if ctx->Extensions.ARB_geometry_shader4 is false. This patch adds a new function, _mesa_has_geometry_shaders(), which returns true if either ARB_geometry_shader4 is supported or the GL version is at least 3.2 desktop. Since compute_version() only enables GL 3.2 functionality when GLSL 1.50 support is present, a sufficient way for a back-end to advertise geometry shader support is to set ctx->Const.GLSLVersion >= 150. v2: Remove unnecessary ctx->Const.GeometryShaders150 constant.

* glsl/linker: Make update_array_sizes apply to just uniforms.Paul Berry2013-08-011-3/+1
| | | | | | | | | | | | | | | | | | | | Commit 586b4b5 (glsl: Also update implicit sizes of varyings at link time) extended update_array_sizes() to apply to both uniforms and shader ins/outs. However, doing creates problems for geometry shaders, because update_array_sizes() assumes that variables with matching names in different parts of the pipeline should have the same sizes. With the addition of geometry shaders, this is no longer true (e.g. both vertex and geometry shaders have a gl_ClipDistance output variable, but there's no reason these variables should have the same sizes). The original reason for commit 586b4b5 (avoid problems with gl_TexCoord being 0 length) has since been addressed by commit 6f53921 (linker: Ensure that unsized arrays have a size after linking). So go ahead and switch update_array_sizes() back to only acting on uniforms. Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

However, indexing with an out-of-range value that isn't constant merely results in undefined results. Since optimization passes (e.g. loop unrolling) can convert non-constant array indices into constant array indices, it's possible that ir_set_program_inouts will encounter a constant array index that is out of range; if this happens, just mark the whole array as used.

| | | | | | | | | | | | | | | | | | | | | | | The code in ir_set_program_inouts that marks just a portion of a variable as used (rather than the whole variable) only works on a few kinds of indexing operations: - Indexing into matrices - Indexing into arrays of matrices, vectors, or scalars. Fortunately these are the only kinds of indexing operations that we expect to see; everything else is either handled by a previously-executed lowering pass or prohibited by GLSL. However, that could conceivably change in the future (the GLSL rules might change, or we might modify the lowering passes). To avoid mysterious bugs in the future, let's have ir_set_program_inouts report an assertion failure if it ever encounters an unexpected kind of indexing operation (and in release builds, fall back to just marking the whole variable as used).

* gallium: clarify shift behavior with shift count >= 32Roland Scheidegger2013-08-021-12/+18
| | | | | | | | | | | | | | | | | | Previously, nothing was said what happens with shift counts exceeding bit width of the values to shift. In theory 3 behaviors are possible: 1) undefined (classic c definition) 2) just shift out all bits (so result is zero, or -1 potentially for ashr) 3) mask the shift count to bit width - 1 API's either require 3) or are ok with 1). In particular, GLSL (as well as a couple uninteresting legacy GL extensions) is happy with undefined, whereas both OpenCL and d3d10 require 3). Consequently, most hw also implements 3). So, for simplicity we just specify that 3) is required rather than saying undefined and then needing state trackers to work around it. Also while here specify shift count as a vector, not scalar. As far as I can tell this was a doc bug, neither state trackers nor drivers used scalar shift count. Reviewed-by: Jose Fonseca <[email protected]>

And why would you only invalidate on a server that emits invalidate events, when the comment said to emit invalidates if the server *doesn't*? Only, I missed that we otherwise don't flag that our buffers might have changed at swap time at all, so the driver was only checking for new buffers when triggered by the Viewport hack. Of course you don't expect Viewport to be called after a swap.
