## 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"

## b) Test how we dump unprintable chars.
## ['\t', '\0', '\001', '\0', '\\', '0', '0', '1', '\0']
# RUN: yaml2obj -DCONTENT="090001005C30303100" %s -o %t2.o

# ESCAPED-NEXT: 0x00000000: "\t"
# ESCAPED-NEXT: 0x00000002: "\001"
# ESCAPED-NEXT: 0x00000004: "\\001"
# ESCAPED-EMPTY:
## c) Test that llvm-dwarfdump emits a warning when it encounters a string without a null terminator.
## "abc\0" "abc"
# RUN: yaml2obj -DCONTENT="61626300616263" %s -o %t3.o
# RUN: llvm-dwarfdump --debug-str %t3.o 2>&1 | FileCheck %s --check-prefix=WARN
# WARN: .debug_str contents:

# WARN-NEXT: warning: no null terminated string at offset 0x4
# WARN: .debug_str.dwo contents:
# WARN-NEXT: 0x00000000: "abc"
# WARN-NEXT: warning: no null terminated string at offset 0x4
