## Test the -D and -U flags of llvm-ranlib
## Create an archive with timestamps but without symbol table
## Important: all `llvm-ar tv` calls must use TZ=UTC to produce identical values
# RUN: yaml2obj %S/../llvm-ar/Inputs/add-lib1.yaml -o %t.o
# RUN: env TZ=UTC touch -t 200001020304 %t.o
# RUN: rm -f %t.a %t-no-index.a && llvm-ar cqSU %t-no-index.a %t.o

## Check that the intial listing has real values:
# RUN: env TZ=UTC llvm-ar tv %t-no-index.a | FileCheck %s --check-prefix=REAL-VALUES

## Check that the -D flag clears the timestamps:
# RUN: cp %t-no-index.a %t.a && llvm-ranlib -D %t.a
# RUN: env TZ=UTC llvm-ar tv %t.a | FileCheck %s --check-prefix=DETERMINISTIC-VALUES

## Check that the -U flag maintains the timestamps:
# RUN: cp %t-no-index.a %t.a && llvm-ranlib -U %t.a
# RUN: env TZ=UTC llvm-ar tv %t.a | FileCheck %s --check-prefix=REAL-VALUES

## Check that we accept multiple values and the last one wins:
# RUN: cp %t-no-index.a %t.a && llvm-ranlib -UDU %t.a
# RUN: env TZ=UTC llvm-ar tv %t.a | FileCheck %s --check-prefix=REAL-VALUES
# RUN: cp %t-no-index.a %t.a && llvm-ranlib -UUD %t.a
# RUN: env TZ=UTC llvm-ar tv %t.a | FileCheck %s --check-prefix=DETERMINISTIC-VALUES

## Check arguments can be passed before and after the file name
# RUN: cp %t-no-index.a %t.a && llvm-ranlib -U %t.a -D -U
# RUN: env TZ=UTC llvm-ar tv %t.a | FileCheck %s --check-prefix=REAL-VALUES

## Check that the -D/-U option is only accepted with a single dash. This matches
## the GNU ranlib behaviour.
# RUN: not llvm-ranlib --D %t.a 2>&1 | FileCheck %s --check-prefix=BAD-OPT-D
# BAD-OPT-D: error: Invalid option: '--D'
# RUN: not llvm-ranlib --U %t.a 2>&1 | FileCheck %s --check-prefix=BAD-OPT-U
# BAD-OPT-U: error: Invalid option: '--U'
# RUN: not llvm-ranlib -x %t.a 2>&1 | FileCheck %s --check-prefix=BAD-OPT-x
# BAD-OPT-x: error: Invalid option: '-x'

## If the first argument starts with value flags, the error message only shows
## the remainder of the parsed string:
# RUN: not llvm-ranlib -Dx %t.a 2>&1 | FileCheck %s --check-prefix=BAD-OPT-x
# RUN: not llvm-ranlib -DxD %t.a 2>&1 | FileCheck %s --check-prefix=BAD-OPT-xD
# BAD-OPT-xD: error: Invalid option: '-xD'
