llvm/llvm/test/tools/llvm-objcopy/ELF/overlapping-sections-in-segments.test

## This test shows that llvm-objcopy does not baulk at overlapping sections
## where such sections are within segments.
## These don't really make sense, but the tool should still handle invalid
## inputs somehow.
# RUN: yaml2obj %s -o %t.o

## Check that the contents are as expected before the copy.
# RUN: llvm-readobj -x .first -x .second %t.o | FileCheck %s --check-prefix=CONTENTS

## Now check that the section contents are still correct after the copy and show that
## llvm-objcopy hasn't "unoverlapped" these sections because they are in segments.
# RUN: llvm-objcopy %t.o %t2.o
# RUN: llvm-readobj --section-headers %t2.o | FileCheck %s
