# CHECK: warning: could not find referenced DIE

# We've modified the DW_AT_abstract_origin offset to reference a NULL DIE.
#
# Source:
#
#   void f1() {}
#   __attribute__((always_inline)) void f2() {
#     f1();
#   }
#   int main() {
#     f2();
#   }
#
# Compile with:
#
#   $ clang -g null_die.c -O0 -S -o null_die.s
#
#   Manually patch the DW_AT_abstract_origin to point to a NULL DIE.
#
#   $ llvm-mc -triple x86_64-apple-darwin -filetype=obj -o null_die.o null_die.s
#
# To generate the debug map:
#
#   $ ld -arch x86_64 -macosx_version_min 10.13.0 -lSystem null_die.o -o null_die
#   $ dsymutil -dump-debug-map null_die
