basic-executable-copy.test 8.32 KB
## 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.
