## In this test case we check that we can override the default values for
## ELF header fields in the YAML.
## First we check the default values.
# RUN: yaml2obj %s -o %t-default
# RUN: llvm-readelf --file-headers %t-default | FileCheck %s --check-prefix=DEFAULT
# DEFAULT: Start of program headers: 64 (bytes into file)
# DEFAULT: Start of section headers: 200 (bytes into file)
# DEFAULT: Size of program headers: 56 (bytes)
# DEFAULT: Number of program headers: 2
# DEFAULT: Size of section headers: 64 (bytes)
# DEFAULT: Number of section headers: 3
# DEFAULT: Section header string table index: 2
--- !ELF
FileHeader:
Class: ELFCLASS64
Data: ELFDATA2LSB
Type: ET_REL
ProgramHeaders:
- Type: PT_LOAD

## Check we can override all default values using the same values
## and that this does not change the output.
# RUN: yaml2obj --docnum=2 %s -o %t-default-override
# RUN: cmp %t-default %t-default-override
