Julian Lettner	1d7790604c	[UBSan] Increase robustness of tests ... These UBSan tests assert the absence of runtime errors via `count 0`, which means "expect no output". This fails the test unnecessarily in some environments (e.g., iOS simulator in our case). Alter the test to be a bit more specific and "expect no error" instead of "expect no output". rdar://65503408 Differential Revision: https://reviews.llvm.org/D85155	2020-08-03 15:26:58 -07:00
