* glsl: Handle the inout qualifier in fragment shader output declarations.Francisco Jerez2016-08-241-0/+12
| | | | | | | | | | | | According to the EXT_shader_framebuffer_fetch extension the inout qualifier can be used on ESSL 3.0+ shaders to declare a special kind of fragment output that gets implicitly initialized with the previous framebuffer contents at the current fragment coordinates. In addition we allow using the same language to define FB fetch outputs in GLSL 1.3+ shaders in preparation for the desktop MESA_shader_framebuffer_fetch extensions.

* glsl: Fix invariant matching in GLSL 4.30 and GLSL ES 1.00.Kenneth Graunke2016-08-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | Old languages (GLSL <= 4.20 and GLSL ES 1.00) require "invariant" to be specified on both inputs and outputs, and match when linking. New languages only allow outputs to be qualified as "invariant" and remove the "invariant must match" restriction when linking varyings (because no input can have that qualifier). Commit 426a50e2089b12d33f5c075aa5622f64076914a3 introduced the new behavior for ES 3.00. It also removed the "must match" restriction for ES 1.00 shaders, which I believe is incorrect. This patch adds that back, as well as making 4.30+ follow the new rules. Thanks to Qiankun Miao for noticing this discrepancy.

* glsl/parser: handle multiple layout sections with AST nodes.Dave Airlie2016-05-231-0/+2
| | | | | | | | | | | | | For geometry/compute inputs and tess control outputs, we create an AST node to keep track of some things. However if we have multiple layout sections, we don't ever link the node into the AST. This is because we create the node on the rightmost layout declaration and don't pass it back in so it gets linked at the end of the parsing of the rightmost.

* glsl: parse new transform feedback layout qualifiersTimothy Arceri2016-03-311-0/+25
| | | | | | | | | | | | | | | | | | | | | | We reuse the existing offset field for holding the xfb_offset expression but create a new flag as to avoid hitting the rules for the offset qualifier for UBOs. xfb_buffer qualifiers require extra processing when merging as they can be applied to global out defaults. We just apply the same rules as we do for the stream qualifier as the spec says: "The *xfb_buffer* qualifier follows the same conventions, behavior, defaults, and inheritance rules as the qualifier stream, and the examples for stream apply here as well." For xfb_stride we push everything into a global out field for later processing as xfb_stride applies to the entire buffer. We still need to have a separate field to store per variable strides because they can still effect implicit offsets e.g. when applied to block members with implicit offsets.

* glsl: Add function parameters to the parser symbol table.Kenneth Graunke2016-03-071-0/+2
| | | | | | | | | | | | | | | | | | | In a shader such as: struct S { float f; } float identity(float S) { return S; } we would think that "S" in "return S" referred to a structure, even though it's shadowed by the "float S" parameter in the inner struct. This led to the parser's grammar seeing TYPE_IDENTIFIER and getting confused. Fixes dEQP-GLES2.functional.shaders.scoping.valid. function_parameter_hides_struct_type_{vertex,fragment}.

| | | | | | | | | | | | | | | | | | | | | | | The lexer/parser use a symbol table to classify identifiers as variables, functions, or structure types. For some reason, we neglected to add variables in simple declarations such as int x = 5; but did add subsequent variables in multi-declarations: int x = 5, y = 6; // y gets added, but not x, for some reason Fixes four dEQP-GLES2.functional.shaders.scoping.valid subcases: - local_int_variable_hides_struct_type_vertex - local_int_variable_hides_struct_type_fragment - local_struct_variable_hides_struct_type_vertex - local_struct_variable_hides_struct_type_fragment Signed-off-by: Kenneth Graunke <kenneth@whitecape.org> Reviewed-by: Timothy Arceri <timothy.arceri@collabora.com>
