# REQUIRES: x86
## Test SORT_BY_INIT_PRIORITY can be used to convert .ctors into .init_array

# RUN: split-file %s %t
# RUN: llvm-mc -filetype=obj -triple=x86_64 %t/asm -o %t.o
# RUN: ld.lld -T %t/lds %t.o -o %t.out
# RUN: llvm-readelf -x .init_array %t.out | FileCheck %s

# CHECK:      Hex dump of section '.init_array':
# CHECK-NEXT: 0x00000001 00010203 04050607

## Test REVERSE can be used to reverse the order of .init_array and .ctors

# RUN: ld.lld -T %t/reverse.lds %t.o -o %t2.out
# RUN: llvm-readelf -x .init_array %t2.out | FileCheck %s --check-prefix=CHECK2

# CHECK2:      Hex dump of section '.init_array':
