## For implicit string table sections, the `Flags` field can also
## be specified in YAML. Here we test the behavior in different cases.

## When flags are not explicitly specified, yaml2obj assigns no flags
## for .strtab and the SHF_ALLOC flag for .dynstr by default.

# RUN: yaml2obj --docnum=1 %s -o %t1
# RUN: llvm-readobj %t1 -S | FileCheck %s --check-prefix=CASE1

# CASE1:      Name: .dynstr
# CASE1-NEXT: Type: SHT_STRTAB
# CASE1-NEXT: Flags [
