## For implicit symbol table sections, `Size` and/or `Content` fields can also
## be specified in YAML. Here we test the behavior in different cases.

## When no `Size` or `Content` is specified for a symbol table section,
## yaml2obj writes the default content.

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