; REQUIRES: x86-registered-target
; Compile with thinlto indices, to enable thinlto.
; RUN: opt -module-summary %s -o %t1.bc
; Test old lto interface with thinlto (currently known to be broken, so
; the FileCheck line is commented out).
; FIXME: The new LTO implementation has been fixed to not internalize
; (and later dead-code-eliminate) builtin functions. However the old LTO
; implementation still internalizes them, and when used with ThinLTO they
; get dead-code eliminated before the optimizations run that insert calls
; to them (thus breaking these inserted calls). This needs to be fixed.
; RUN: llvm-lto -exported-symbol=main -thinlto-action=run %t1.bc
;;; RUN llvm-nm %t1.bc.thinlto.o | FileCheck %s --check-prefix=CHECK-NM
; Test new lto interface with thinlto.

; RUN: llvm-nm %t.out.1 | FileCheck %s --check-prefix=CHECK-NM
;
; Re-compile, this time without the thinlto indices.
; RUN: opt %s -o %t4.bc

; RUN: llvm-nm %t5.out.0 | FileCheck %s --check-prefix=CHECK-NM
; Test the old lto interface without thinlto. For now we need to
; use a different nm check, because currently the old lto interface
; internalizes these symbols. Once the old lto interface gets
; fixed, we should be able to use the same CHECK-NM tests as the
; other FileChecks.
; RUN: llvm-lto -exported-symbol=main %t4.bc -o %t6
; RUN: llvm-nm %t6 | FileCheck %s --check-prefix=CHECK-NM2
; The final binary should not contain any of the dead functions;
; make sure memmove and memcpy are there.
; CHECK-NM-NOT: bar
; CHECK-NM-DAG: T __stack_chk_fail
; CHECK-NM-NOT: bar
; Test case for old lto without thinlto. Hopefully these can be
; eliminated once the old lto interface is fixed.
