1## This test verifies that llvm-objcopy can add multiple sections to a Mach-O binary.

7## Case 1: Add a new section twice into an existing segment.
8# RUN: llvm-objcopy --add-section __TEXT,__foo=%t.foo.data %t %t.foo.1

18## Case 3: Add two new sections into two different segments.
19# RUN: llvm-objcopy --add-section __FOO,__foo=%t.foo.data --add-section __BAR,__bar=%t.bar.data %t %t.foo.bar.3
