## This test verifies that llvm-objcopy copies an executable properly. It
## uses llvm-readobj instead of cmp because some parts of the object
## (e.g., the string table) are not identical; the output file is correct but
## some offsets differ from the input file.
# RUN: yaml2obj %s -o %t
# RUN: llvm-objcopy %t %t2
# RUN: llvm-readobj --file-headers --sections %t2 | FileCheck %s
