test/tools/obj2yaml/elf-hash-section.yaml

## Check how obj2yaml produces SHT_HASH section descriptions.

## Check that obj2yaml uses "Bucket" and "Chain" tags to describe
## a SHT_HASH section when it has content of a correct size.
## I.e. data size == 4 * (2 + nbucket + nchain).

# RUN: yaml2obj --docnum=1 %s -o %t1
# RUN: obj2yaml %t1 | FileCheck %s --check-prefix=CHAIN-BUCKET

# CHAIN-BUCKET:      - Name:  .hash1
# CHAIN-BUCKET-NEXT:  Type:   SHT_HASH
# CHAIN-BUCKET-NEXT:  Bucket: [ 3 ]
# CHAIN-BUCKET-NEXT:  Chain:  [ 4, 5 ]
# CHAIN-BUCKET:      - Name:  .hash2
# CHAIN-BUCKET-NEXT:  Type:   SHT_HASH
# CHAIN-BUCKET-NEXT:  Bucket: [  ]
# CHAIN-BUCKET-NEXT:  Chain:  [  ]
