What is BIGGEST_ALIGNMENT? Does a 64-bit value require a 64-bit alignment? If not, perhaps BIGGEST_ALIGNMENT should be 32. If BIGGEST_ALIGNMENT must be 64 for some reason, but in this specific case you have a DImode value which does not require 64-bit alignment, then I agree that there is a case missing from the compiler. Unfortunately it looks like it may be painful to fix, as the proper fix will entail using TYPE_ALIGN of the type, but the type is not currently available in emit_library_call_value Ian
