## llvm-mc doesn't support generating ET_CORE files; the 'Content' field was
## generated with the following steps:

# $ bin/llvm-objcopy --dump-section=.note.foo=tmp.txt tmp.o /dev/null
# $ xxd -p tmp.txt | tr -d '\n'; echo

# .section ".note.foo", "a"
#       .align 4
#       .long 5 /* namesz */
#       .long end - begin /* descsz */
