## Check for basic functionality using an input file with
## various section types, adresses, data, and no segments.
# RUN: yaml2obj %s --docnum=1 -o %t
# RUN: llvm-objcopy -O srec %t - | \
# RUN:   FileCheck --match-full-lines --strict-whitespace %s --check-prefix=SREC

## The record type for the header should be S0 with a 2 byte address
## of 0. For an output file named "-" the header data field should contain "2D".
## The byte count field should therefore have a value of 4: 2 bytes for address,
## 1 byte for output file and 1 byte for checksum.
