; RUN: opt -S -globalopt < %s | FileCheck %s
; LOCALMOD: We've changed the heuristic used to detect "main" for the GlobalOpt
; optimization of replacing globals with allocas. Revert this when fixed
; properly upstream (http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-July/063580.html)
; XFAIL: *
; PR6112 - When globalopt does RAUW(@G, %G), the metadata reference should drop
; to null. Function local metadata that references @G from a different function
; to that containing %G should likewise drop to null.
@G = internal global i8** null
define i32 @main(i32 %argc, i8** %argv) {
; CHECK: @main
; CHECK: %G = alloca
store i8** %argv, i8*** @G
ret i32 0
}
define void @foo(i32 %x) {
call void @llvm.foo(metadata !{i8*** @G, i32 %x})
; CHECK: call void @llvm.foo(metadata !{null, i32 %x})
ret void
}
declare void @llvm.foo(metadata) nounwind readnone
!named = !{!0}
!0 = metadata !{i8*** @G}
; CHECK: !0 = metadata !{null}
