## output files.

## Test that llvm-strip reports a proper error when --preserve-dates is specified
## with one or more inputs, where one of them is stdin.
# RUN: not llvm-strip --preserve-dates - < %t.foo 2>&1 | FileCheck %s
# RUN: not llvm-strip --preserve-dates %t.foo - < %t.foo 2>&1 | FileCheck %s

# RUN: not llvm-strip --preserve-dates %t.foo - %t.foo < %t.foo 2>&1 | FileCheck %s

## Testing -o.

# RUN: not llvm-strip --preserve-dates %t.foo -o - < %t.foo 2>&1 | FileCheck %s

# CHECK: error: --preserve-dates requires a file
