* c-typeck.c (store_init_value): Don't require constant initializer elements with -pedantic -std=c99. (digest_init): Change error about non-constant initializer elements into pedwarn. (constructor_range_end): Remove. (constructor_incremental, designator_depth, designator_errorneous): New variables. (struct constructor_stack): Remove range_end, add incremental. (struct constructor_range_stack, constructor_range_stack): New. (struct initializer_stack): Add constructor_range_stack. (finish_init): Set it. (start_init): Likewise. require_constant_elements for non-static trees only if not flag_isoc99. (really_start_incremental_init): Remove constructor_range_end, add constructor_incremental. (pop_init_level): Likewise. (push_init_level): Likewise. If implicit and the subobject had some value set already, preinitialize the level with it. Warn about missing braces only if not pushing due to designators. (set_designator, push_range_stack): New functions. (set_init_label): Use them. (set_init_index): Likewise. Remove constructor_range_end. Error if designator index is outside of array bounds. (add_pending_init): Compare values of purpose index trees, not the trees themselves. Allow overwriting of already initialized element. Issue a warning if it had side-effects. (set_nonincremental_init, set_nonincremental_init_from_string): New functions. (pending_init_member): Rename to... (find_init_member): ...this function. Call set_nonincremental_init if necessary. Compare values of purpose index trees, not the trees themselves. Return the actual value, not just non-zero if something is found. (output_init_element): Remove checks for duplicates. If field has zero size, only check the initializer for correctness. Call set_nonincremental_init if necessary. Push RECORD/ARRAY into AVL if constructor_incremental is zero. Change error about initializers not computable at load time into pedwarn. (output_pending_init_elements): Compare bit positions, not FIELD_DECLs to take into account zero-sized fields. (process_init_element): Use constructor_range_stack to fill all ranges in the designator lists from current level up. * extend.texi: Update documentation for labeled elements. * gcc.c-torture/execute/20000801-3.x: Remove. * gcc.dg/c90-init-1.c: New test. * gcc.dg/c99-init-1.c: New test. * gcc.dg/c99-init-2.c: New test. * gcc.dg/gnu99-init-1.c: New test.
