-; Test case obtained from the following C code:
-
-; struct A {
-;  int field1;
-;  short field2;
-; };
-;
-; struct B {
-;   struct A field1;
-;   int field2;
-; };
-;
-;
-; extern struct B g_b;
-; extern int bar(struct B b, int c);
-;
-; int foo(int cond) {
-;   int result = cond ? bar(g_b, 33) : 42;
-;   return result;
-; }
-
-; In this test, global variable g_b is passed by copy to function bar. That
-; copy is located on the stack (see alloca %g_b.coerce), and it is initialized
-; by a memcpy call.
-;
-; SROA would split alloca %g_b.coerce into two (smaller disjoint) slices:
-; slice [0,8) and slice [8, 12). Users of the original alloca are rewritten
-; as users of the new alloca slices.
-; In particular, the memcpy is rewritten by SROA as two load/store pairs.
-;
-; Later on, mem2reg successfully promotes the new alloca slices to registers,
-; and loads %3 and %5 are made redundant by the loads obtained from the memcpy
-; intrinsic expansion.
-;
-; If pass AddDiscriminators doesn't assign a discriminator to the intrinsic
-; memcpy call, then the loads obtained from the memcpy expansion would not have
-; a correct discriminator.
-;
-; This test checks that the two new loads inserted by SROA in %cond.true
-; correctly reference a debug location with a non-zero discriminator. This test
-; also checks that the same discriminator is used by all instructions from
-; basic block %cond.true.
