## Test how the Machine YAML field can be used to set the e_machine ELF header field.

## Test we can use an arbitrary value.

# RUN: yaml2obj -D MACHINE=0x1234 %s -o %t1
# RUN: llvm-readelf %t1 --file-headers | FileCheck %s --check-prefix=UNKNOWN

# UNKNOWN: Machine: 1234

--- !ELF
FileHeader:
  Class:   ELFCLASS64
  Data:    ELFDATA2MSB
  Type:    ET_REL
  Machine: [[MACHINE]]

## Test we can't use a number that doesn't fit into 2 bytes.

# RUN: not yaml2obj -D MACHINE=0x12345 %s 2>&1 | FileCheck %s --check-prefix=ERR

# ERR: error: out of range hex16 number

## Test we can use a known named constant.

# RUN: yaml2obj -D MACHINE=EM_NONE %s -o %t3
# RUN: llvm-readelf %t3 --file-headers | FileCheck %s --check-prefix=NONE

# NONE: Machine: None

## Test we can't use an unknown string constant.

# RUN: not yaml2obj -D MACHINE=EM_UNKNOWN_FOO %s 2>&1 | FileCheck %s --check-prefix=ERR2

# ERR2: error: invalid hex16 number
