From 63f394203a8be9b87f8617cd7a56a0806c0870b3 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Mon, 5 Apr 2010 14:35:47 -0700 Subject: [PATCH] Set lower bound on size implied by whole-array assignment When an unsized array is accessed with a constant extension index this sets a lower bound on the allowable sizes. When the unsized array gets a size set due to a whole-array assignment, this size must be at least as large as the implied lower bound. This causes the following tests to pass: glslparsertest/glsl2/array-16.vert --- ast_to_hir.cpp | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/ast_to_hir.cpp b/ast_to_hir.cpp index c9f93cbcc42..9d067be02d7 100644 --- a/ast_to_hir.cpp +++ b/ast_to_hir.cpp @@ -489,6 +489,13 @@ do_assignment(exec_list *instructions, struct _mesa_glsl_parse_state *state, assert(var != NULL); + if (var->max_array_access >= unsigned(rhs->type->array_size())) { + /* FINISHME: This should actually log the location of the RHS. */ + _mesa_glsl_error(& lhs_loc, state, "array size must be > %u due to " + "previous access", + var->max_array_access); + } + var->type = glsl_type::get_array_instance(lhs->type->element_type(), rhs->type->array_size()); } -- 2.30.2
