Douglas Gregor	caa1bf434d	Emit an error if an array is too large. We're slightly more strict than GCC 4.2 here when building 32-bit (where GCC will allow allocation of an array for which we can't get a valid past-the-end pointer), and emulate its odd behavior in 64-bit where it only allows 63 bits worth of storage in the array. The former is a correctness issue; the latter is harmless in practice (you wouldn't be able to use such an array anyway) and helps us pass a GCC DejaGNU test. Fixes <rdar://problem/8212293>. llvm-svn: 111338	2010-08-18 00:39:00 +00:00
