X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=91b8ecbe1c134604fc87b3761a308b15a6caf394;p=mesa.git glsl: Disallow primitive type layout qualifier on variables. This only makes any sense on the GS input or output layout declaration, nowhere else. Fixes the piglit tests: * spec/glsl-1.50/compiler/incorrect-in-layout-qualifiers-with-variable-declarations.geom * spec/glsl-1.50/compiler/incorrect-out-layout-qualifiers-with-variable-declarations.geom * spec/glsl-1.50/compiler/layout-fs-no-output.frag * spec/glsl-1.50/compiler/layout-vs-no-input.vert * spec/glsl-1.50/compiler/layout-vs-no-output.vert Signed-off-by: Chris Forbes Reviewed-by: Kenneth Graunke --- diff --git a/src/glsl/ast_to_hir.cpp b/src/glsl/ast_to_hir.cpp index 132a955b781..92e0f90b81c 100644 --- a/src/glsl/ast_to_hir.cpp +++ b/src/glsl/ast_to_hir.cpp @@ -2469,6 +2469,13 @@ apply_type_qualifier_to_variable(const struct ast_type_qualifier *qual, _mesa_shader_stage_to_string(state->stage)); } + /* Disallow layout qualifiers which may only appear on layout declarations. */ + if (qual->flags.q.prim_type) { + _mesa_glsl_error(loc, state, + "Primitive type may only be specified on GS input or output " + "layout declaration, not on variables."); + } + /* Section 6.1.1 (Function Calling Conventions) of the GLSL 1.10 spec says: * * "However, the const qualifier cannot be used with out or inout."
