From: Kalyan Kondapally <kalyan.kondapa...@intel.com> Dynamic indexing of sampler arrays is prohibited by GLSL ES 3.00. Earlier versions allow 'constant-index-expression' indexing, where index can contain a loop induction variable.
Patch allows dynamic indexing for sampler arrays when GLSL ES < 3.00. This change makes 'sampler-array-index.frag' parser test in Piglit pass + fishgl.com works when running Chrome on OpenGL ES 2.0 backend. v2: small change and some more commit message (Tapani) Signed-off-by: Kalyan Kondapally <kalyan.kondapa...@intel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=84225 --- src/glsl/ast_array_index.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/glsl/ast_array_index.cpp b/src/glsl/ast_array_index.cpp index ecef651..b2609b6 100644 --- a/src/glsl/ast_array_index.cpp +++ b/src/glsl/ast_array_index.cpp @@ -226,7 +226,7 @@ _mesa_ast_array_index_to_hir(void *mem_ctx, * dynamically uniform expression is undefined. */ if (array->type->element_type()->is_sampler()) { - if (!state->is_version(130, 100)) { + if (!state->is_version(130, 300)) { if (state->es_shader) { _mesa_glsl_warning(&loc, state, "sampler arrays indexed with non-constant " -- 2.1.0 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
