1## Show that llvm-strings can handle stdin input properly.

3## Case 1: output with single string.
4RUN: echo -n "abcdefg" | llvm-strings - | FileCheck %s --check-prefix=CASE1 --implicit-check-not={{.}}

7## Case 2: output too short for string.
8RUN: echo -n "abc" | llvm-strings - | FileCheck %s --implicit-check-not={{.}} --allow-empty

10## Case 3: output with new line.
11RUN: echo -e "abcd\nefgh" | llvm-strings - | FileCheck %s --check-prefix=CASE3 --implicit-check-not={{.}}

15## Case 4: output containing unprintable characters.
16RUN: echo -e "abcd\x00ef\x1fghij\x7fklmn" | llvm-strings - | FileCheck %s --check-prefix=CASE4 --implicit-check-not={{.}}
17CASE4:      abcd

21## Case 5: no file name specified is equivalent to explicitly requesting stdin.
