; LTO ; This doesn't currently work with gold, because it does not apply defsym ; renaming to symbols in the same module (apparently by design for consistency ; with GNU ld). Because regular LTO hands back a single object file to gold, ; it doesn't perform the desired defsym renaming. This isn't an issue with ; ThinLTO which hands back multiple native objects to gold. For regular ; LTO defsym handling, gold will need a fix (not the gold plugin). ; RUN-TODO: llvm-as %s -o %t.o ; RUN-TODO: llvm-as %S/Inputs/wrap-bar.ll -o %t1.o ; RUN-TODO: %gold -plugin %llvmshlibdir/LLVMgold%shlibext %t.o %t1.o -shared -o %t.so -wrap=bar ; RUN-TODO: llvm-objdump -d %t.so | FileCheck %s ; RUN-TODO: llvm-readobj -t %t.so | FileCheck -check-prefix=BIND %s ; ThinLTO ; RUN: opt -module-summary %s -o %t.o ; RUN: opt -module-summary %S/Inputs/wrap-bar.ll -o %t1.o ; RUN: %gold -plugin %llvmshlibdir/LLVMgold%shlibext %t.o %t1.o -shared -o %t.so -wrap=bar ; RUN: llvm-objdump -d %t.so | FileCheck %s -check-prefix=THIN ; RUN: llvm-readobj -t %t.so | FileCheck -check-prefix=BIND %s ; Make sure that calls in foo() are not eliminated and that bar is ; routed to __wrap_bar and __real_bar is routed to bar. ; CHECK: foo: ; CHECK-NEXT: pushq %rax ; CHECK-NEXT: callq{{.*}}<__wrap_bar> ; CHECK-NEXT: callq{{.*}} ; THIN: foo: ; THIN-NEXT: pushq %rax ; THIN-NEXT: callq{{.*}}<__wrap_bar> ; THIN-NEXT: popq %rax ; THIN-NEXT: jmp{{.*}} ; Check that bar and __wrap_bar retain their original binding. ; BIND: Name: bar ; BIND-NEXT: Value: ; BIND-NEXT: Size: ; BIND-NEXT: Binding: Local ; BIND: Name: __wrap_bar ; BIND-NEXT: Value: ; BIND-NEXT: Size: ; BIND-NEXT: Binding: Local target datalayout = "e-m:e-i64:64-f80:128-n8:16:32:64-S128" target triple = "x86_64-unknown-linux-gnu" declare void @bar() declare void @__real_bar() define void @foo() { call void @bar() call void @__real_bar() ret void }
