Thanks for the test case! I can reproduce this, and see with the compiler I saved from just before r278338 that this is indeed a chance in behavior. Looking at why this changed...

I guess we should compare the *size* first, and only do something if the size differs.

Hi, Recently, I noticed that less number of global variables are merged in global-merge pass and in some global variable, array types are used instead of its original type. For example, [4xi8] with align 4 is used for a i32 global variable. For me, it seems that such pattern is observed after r278338 (Resolution-based LTO API). Can anyone give me little bit more insight if such type change was intended? If then why such uses of array type is needed?
