## Test that NT_FILE sections in core files are interpreted correctly.

# RUN: yaml2obj %s -o %t.o
# RUN: llvm-readelf --notes %t.o | FileCheck %s --check-prefix=GNU
# RUN: llvm-readobj --notes %t.o | FileCheck %s --check-prefix=LLVM

## llvm-mc doesn't support generating ET_CORE files; the 'Content' field was
## generated with the following steps:
# $ llvm-mc -filetype=obj -triple x86_64-pc-linux-gnu tmp.s -o tmp.o
# $ bin/llvm-objcopy --dump-section=.note.foo=tmp.txt tmp.o /dev/null
# $ xxd -p tmp.txt | tr -d '\n'; echo
## Using the following input:
# .section ".note.foo", "a"
#       .align 4
#       .long 5 /* namesz */
#       .long end - begin /* descsz */
#       .long 0x46494c45 /* type = NT_FILE */
#       .asciz "CORE"
#       .align 4
# begin:
#       .quad 3 /* 3 file mappings */
#       .quad 4096 /* page size */
#       .quad 0x1000 /* start #1 */
#       .quad 0x2000 /* end #1 */
