## a) Show that llvm-dwarfdump dumps the .debug_str and
## .debug_str.dwo sections when --debug-str is specified.
## "some string\0foo\0\0"
# RUN: yaml2obj -DCONTENT="736f6d6520737472696e6700666f6f0000" %s -o %t.o
# RUN: llvm-dwarfdump %t.o --debug-str | FileCheck %s
# CHECK: .debug_str contents:
# CHECK-NEXT: 0x00000000: "some string"
# CHECK-NEXT: 0x0000000c: "foo"

## b) Test how we dump unprintable chars.
## ['\t', '\0', '\001', '\0', '\\', '0', '0', '1', '\0']

## c) Test that llvm-dwarfdump emits a warning when it encounters a string without a null terminator.
## "abc\0" "abc"
