Test the 'u' option of llvm-ar
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.older
RUN: echo older > %t.older/evenlen
Either the shell supports the 'touch' command with a flag to manually set the
mtime or we sleep for over a second so that the mtime is definitely observable.
RUN: touch -m -t 200001010000 %t.older/evenlen || sleep 1.1
RUN: mkdir -p %t.newer
RUN: echo newer > %t.newer/evenlen
RUN: touch %t.newer/evenlen
Create an achive with the newest file
RUN: llvm-ar r %t.a %t.newer/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 %t.older/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.newer/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 %t.older/evenlen
RUN: llvm-ar p %t.a | FileCheck --check-prefix=NEWER %s
NEWER: newer
OLDER: older
