* dwarf2read.c (read_array_type): Read the DW_AT_byte_size from the DIE and set the length of the type. * gdbtypes.h (get_array_bounds): Move here from valprint.h. * gdbtypes.c (get_array_bounds): Move here from valprint.c and return 0 if the corresponding bounds of the type are undefined. * valprint.h (get_array_bounds): Move declaration to gdbtypes.h. * valprint.c (get_array_bounds): Move implementation to gdbtypes.c. (val_print_array_elements): Use get_array_bounds to compute the number of array elements instead of dividing the length of the array by the length of the element types. * valarith.c (vector_binop): Likewise. * valops.c (value_cast): Likewise. * c-valprint.c (c_val_print): Likewise. * c-typeprint.c (c_type_print_varspec_suffix): Likewise. gdb/testsuite: * gdb.base/gnu_vector.exp: Adjust expect messages.
