# Test .init_array.
# Generated from the following C code:
#
# static void
# init () {}
#
# static void (*const init_array []) ()
#  __attribute__ ((used, section (".init_array"), aligned (sizeof (void *))))
#  = { init };
#
# int
# main() { return (0); }
#
# Note: both STT_OBJECT and STT_SECTION for .init_array are commented in yaml
# declaration to check if lld correct adds the object's .init_array when the
# section has no symbol (some compilers may create object with this behavior,
# specially for C++ global constructors).

#RUN: yaml2obj -format=elf %s -o=%t.o
#RUN: lld -flavor old-gnu -target x86_64 %t.o -o %t -e=main
#RUN: llvm-objdump -t -section-headers %t | FileCheck %s

#CHECK: .init_array {{[0-9]+}} [[ADDR:[0-9]+]]
#CHECK: [[ADDR]] l *ABS* {{[0-9]+}} .hidden __init_array_start
