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