My claim is that we should stop doing this: it should always be 64-bit for x86 and ARM, rather than depending on whether the target is biarch (x86) or whether it is EABI (ARM), just as it is for other targets that may or may not be biarch (MIPS, Power, SPARC). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38934
