1 ## Show that llvm-strings can handle stdin input properly.
3 ## Case 1: output with single string.
4 RUN: echo -n "abcdefg" | llvm-strings - | FileCheck %s --check-prefix=CASE1 --implicit-check-not={{.}}
7 ## Case 2: output too short for string.
8 RUN: echo -n "abc" | llvm-strings - | FileCheck %s --implicit-check-not={{.}} --allow-empty
10 ## Case 3: output with new line.
11 RUN: echo -e "abcd\nefgh" | llvm-strings - | FileCheck %s --check-prefix=CASE3 --implicit-check-not={{.}}
15 ## Case 4: output containing unprintable characters.
16 RUN: echo -e "abcd\x00ef\x1fghij\x7fklmn" | llvm-strings - | FileCheck %s --check-prefix=CASE4 --implicit-check-not={{.}}
21 ## Case 5: no file name specified is equivalent to explicitly requesting stdin.
22 RUN: echo -n "abcdefg" | llvm-strings | FileCheck %s --check-prefix=CASE1 --implicit-check-not={{.}}
