| ## 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: [ ]
