Test the 'u' option of llvm-ar

REQUIRES: shell

RUN: cd %T
RUN: rm -f %t.a

Create a file named evenlen that is newer than the evenlen on the source dir.
RUN: mkdir -p %t.dir
RUN: echo newer > %t.dir/evenlen

Create an achive with the newest file
RUN: llvm-ar r %t.a %t.dir/evenlen
RUN: llvm-ar p %t.a | FileCheck --check-prefix=NEWER %s

Check that without the 'u' option the member is replaced with an older file.
RUN: llvm-ar r %t.a %p/Inputs/evenlen
RUN: llvm-ar p %t.a | FileCheck --check-prefix=OLDER %s

Check that with the 'u' option the member is replaced with a newer file.
RUN: llvm-ar ru %t.a %t.dir/evenlen
RUN: llvm-ar p %t.a | FileCheck --check-prefix=NEWER %s

Check that with the 'u' option the member is not replaced with an older file.
RUN: llvm-ar ru %t.a %p/Inputs/evenlen
RUN: llvm-ar p %t.a | FileCheck --check-prefix=NEWER %s

NEWER: newer
OLDER: evenlen
