llvm/llvm/test/tools/llvm-strings/negative-char.test

## Show that llvm-strings can handle a negative signed char value (i.e. > 0x7f).
## Such characters should form string delimiters like other unprintable ones.

# RUN: echo -e "z\0\x80\0a\0" | llvm-strings --bytes 1 - | FileCheck %s
# CHECK: z{{$}}
