test/tools/yaml2obj/ELF/section-size-content.yaml

## For regular sections, it is common to specify `Size` and/or `Content` fields in YAML.
## Here we test the behavior in different cases.

## In this case, we have both `Content` and `Size` fields specified and `Size`
## is less than content size. Check we report an error.

# RUN: not yaml2obj --docnum=1 %s -o %t1 2>&1 | FileCheck %s --check-prefix=ERR
# ERR: error: Section size must be greater than or equal to the content size
