test/tools/yaml2obj/ELF/header-sh-fields.yaml

## 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
  - 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

--- !ELF
FileHeader:
  Class:      ELFCLASS64
  Data:       ELFDATA2LSB
  Type:       ET_REL
  EShEntSize: [[SHENTSIZE=64]]
  EShOff:     [[SHOFF=200]]
  EShNum:     [[SHNUM=3]]
  EShStrNdx:  [[SHSTRNDX=2]]
  EPhOff:     [[PHOFF=64]]
  EPhEntSize: [[PHENTSIZE=56]]
  EPhNum:     [[PHNUM=2]]

## Override different fields to check the output produced.

## Override the e_shoff field.
# RUN: yaml2obj --docnum=2 %s -DSHOFF=3 -o %t2
# RUN: llvm-readelf --file-headers %t2 | FileCheck %s --check-prefix=SHOFF

# SHOFF: Start of section headers: 3 (bytes into file)

## Override the e_shnum field.
# RUN: yaml2obj --docnum=2 %s -DSHNUM=2 -o %t3
# RUN: llvm-readelf --file-headers %t3 | FileCheck %s --check-prefix=SHNUM

# SHNUM: Number of section headers: 2{{$}}

## Override the e_shstrndx field.
# RUN: yaml2obj --docnum=2 %s -DSHSTRNDX=4 -o %t4
# RUN: llvm-readelf --file-headers %t4 | FileCheck %s --check-prefix=SHSTRNDX

# SHSTRNDX: Section header string table index: 4{{$}}

## Override the e_shentsize field.
## Check the result using raw output from 'od' because llvm-readelf
## is unable to dump such headers.

# RUN: yaml2obj --docnum=2 %s -DSHENTSIZE=1 -o %t5
# RUN: od -A n -t x1 -v -j 0x3a -N 1 %t5 | FileCheck %s --check-prefix=NEWSIZE
# RUN: od -A n -t x1 -v -j 0x3a -N 1 %t-default | FileCheck %s --check-prefix=OLDSIZE
# NEWSIZE: 01
# OLDSIZE: 40

## Override the e_phoff field.
# RUN: yaml2obj --docnum=2 %s -DPHOFF=3 -o %t6
# RUN: llvm-readelf --file-headers %t6 | FileCheck %s --check-prefix=PHOFF

# PHOFF: Start of program headers: 3 (bytes into file){{$}}

## Override the e_phnum field.
# RUN: yaml2obj --docnum=2 %s -DPHNUM=1 -o %t7
# RUN: llvm-readelf --file-headers %t7 | FileCheck %s --check-prefix=PHNUM

# PHNUM: Number of program headers: 1{{$}}

## Override the e_phentsize field.
# RUN: yaml2obj --docnum=2 %s -DPHENTSIZE=1 -o %t8
# RUN: llvm-readelf --file-headers %t8 | FileCheck %s --check-prefix=PHENTSIZE

# PHENTSIZE: Size of program headers: 1 (bytes)
