; This test lets globalopt split the global struct and array into different
; values. The pass needs to preserve section attribute.
; RUN: opt < %s -passes=globalopt -S | FileCheck %s
; Check that the new global values still have their section assignment.
; CHECK: @struct
; CHECK: section ".foo"
; CHECK: @array
; CHECK-NOT: section ".foo"
@struct = internal global { i32, i32 } zeroinitializer, section ".foo"
@array = internal global [ 2 x i32 ] zeroinitializer
define i32 @foo() {
%A = load i32, ptr getelementptr ({ i32, i32 }, ptr @struct, i32 0, i32 0)
%B = load i32, ptr @array
; Use the loaded values, so they won't get removed completely
%R = add i32 %A, %B
ret i32 %R
}
; We put stores in a different function, so that the global variables won't get
; optimized away completely.
