## ** Test the behavior of an empty archive:

## No symbol table emitted for GNU archives
# RUN: rm -f %t.a
# RUN: llvm-ar rcs --format=gnu %t.a
# RUN: not grep -q '/               ' %t.a

## No symbol table for BSD archives
# RUN: rm -f %t.a
# RUN: llvm-ar rcs --format=bsd %t.a
# RUN: not grep -q '__\.SYMDEF' %t.a

## And we do emit a symbol table for DARWIN archives
# RUN: rm -f %t.a
# RUN: llvm-ar rcs --format=darwin %t.a
# RUN: grep -q '__\.SYMDEF' %t.a
