## Check we cannot remove a section containing symbols
## referenced by relocations contained in the object.

# RUN: yaml2obj %s > %t1
# RUN: not llvm-objcopy -R .data %t1 2>&1 | FileCheck %s
# CHECK: error: Section .data can't 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.

# RUN: yaml2obj %s > %t2
# RUN: llvm-objcopy -R .data -R .rela.text %t2 %t3
# RUN: llvm-objdump --section-headers %t3 | FileCheck %s --check-prefix=NOSEC
# NOSEC-NOT: .data
# NOSEC-NOT: .rela.text
