[cfe-dev] [release_34] [compiler_rt] UBSAN test failures on i586

Hi,

I have multiple UBSAN tests failing the same way:

 ******************** TEST 'UndefinedBehaviorSanitizer-AddressSanitizer ::
Integer/uadd-overflow.cpp' FAILED ********************

 Exit Code: 1

 Command Output (stderr):

runtime error: unsigned integer overflow: 10000000000000000000 +
9000000000000000000 cannot be represented in type 'unsigned long long'

So the test expect to see "unsigned long" but output has "unsigned long
long".
