Hey I am wondering how do i have a global variable in GENERIC currently i am doing: tree stack_offset = build_decl (BUILTINS_LOCATION, VAR_DECL, create_tmp_var_name ("__MODULE_STK_OFFS"), sizetype); TREE_STATIC (stack_offset) = 1; TREE_PUBLIC (stack_offset) = 1; TREE_USED (stack_offset) = 1; DECL_INITIAL (stack_offset) = build_int_cst (integer_type_node, 0); rest_of_decl_compilation (stack_offset, 1, 0); Then i add this to the array of stuff you pass to the middle-end but i am getting: <built-in>: In function ‘t.__main_start__’: <built-in>:0:0: internal compiler error: in expand_expr_real_1, at expr.c:9326 Its this assert: /* Variables inherited from containing functions should have been lowered by this point. */ context = decl_function_context (exp); gcc_assert (!context || context == current_function_decl || TREE_STATIC (exp) || DECL_EXTERNAL (exp) /* ??? C++ creates functions that are not TREE_STATIC. */ || TREE_CODE (exp) == FUNCTION_DECL); So it must be because that has no context set but i the idea is that i want in generic to be able to use this global variable: sizetype myglobal void myfunction () { ... sizetype x = myglobal + ... } I hope this makes sense just not sure what the context needs to be set to i think. --Phil
