## Check we cannot remove a section containing symbols
## referenced by relocations contained in the object.
# RUN: yaml2obj %s -o %t1
# RUN: not llvm-objcopy -R .data %t1 2>&1 | FileCheck %s -DINPUT=%t1
# CHECK: error: '[[INPUT]]': section '.data' cannot be removed: (.text+0x1) has relocation against symbol 'foo'
## Check the behavior when we also remove the relocation section.
## We have no reference in this case and hence no error should be emitted.
