## Regression test for https://github.com/llvm/llvm-project/issues/63039

## Use an old version to ensure we do *not* have any compact-unwind.
5
# RUN: llvm-mc -filetype=obj -triple=x86_64-apple-macos9 %s -o %t.o

## Pre-cond: smoke-check that there is really no compact-unwind entries - only dwarfs.

# RUN: llvm-objdump --macho --unwind-info --dwarf=frames %t.o | FileCheck %s --check-prefix=PRE

# PRE-NOT: Contents of __compact_unwind section:

# PRE-NOT: Entry at offset

# PRE: .eh_frame contents:

# PRE: {{[0-9a-f]+}} {{.*}} CIE

## Link should succeed (ie., not crashed due to bug in icf code).

# RUN: %lld -lSystem -lc++ --icf=all -arch x86_64 -arch x86_64 -platform_version macos 11.0 11.0 %t.o -o %t.out

## Post-cond: verify that the final binary has expected eh-frame contents.
