## This test checks that timestamps are set to 0 by default or when the -D
## option is specified, and that they are preserved when the -U option is
## specified.
## We only test timestamps as a proxy for full deterministic writing; i.e. we
## assume UID/GIDs are preserved if timestamps are preserved.

# RUN: yaml2obj %S/Inputs/input1.yaml -o %t-input1.o
# RUN: touch -t 199505050555.55 %t-input1.o

## Test values are set to 0 (by default):
# RUN: llvm-libtool-darwin -static -o %t.lib %t-input1.o
# RUN: env TZ=GMT llvm-ar tv %t.lib | FileCheck %s --check-prefix=CHECK-DETERMINISTIC

## Test values are set to 0 (with -D):
# RUN: llvm-libtool-darwin -static -o %t.lib -D %t-input1.o
# RUN: env TZ=GMT llvm-ar tv %t.lib | FileCheck %s --check-prefix=CHECK-DETERMINISTIC

# CHECK-DETERMINISTIC: {{[[:space:]]1970[[:space:]]}}

## Test values are preserved (with -U):
# RUN: llvm-libtool-darwin -static -o %t.lib -U %t-input1.o
# RUN: env TZ=GMT llvm-ar tv %t.lib | FileCheck %s --check-prefix=CHECK-NONDETERMINISTIC

# CHECK-NONDETERMINISTIC:  {{[[:space:]]1995[[:space:]]}}

## D Flag specified more than once:
# RUN: llvm-libtool-darwin -static -o %t.lib %t-input1.o -D -D 2>&1 | count 0
# RUN: env TZ=GMT llvm-ar tv %t.lib | FileCheck %s --check-prefix=CHECK-DETERMINISTIC

## U Flag specified more than once:
# RUN: llvm-libtool-darwin -static -o %t.lib %t-input1.o -U -U 2>&1 | count 0
# RUN: env TZ=GMT llvm-ar tv %t.lib | FileCheck %s --check-prefix=CHECK-NONDETERMINISTIC

## Both D and U flags specified:
# RUN: not llvm-libtool-darwin -static -o %t.lib %t-input1.o -D -U 2>&1 | \
# RUN:   FileCheck %s --check-prefix=CHECK-ERROR-BOTH

# CHECK-ERROR-BOTH: error: cannot specify both -D and -U flags
