## In this test we test how llvm-readelf prints file headers.

## Case 1: Test EM_386 object.
# RUN: yaml2obj %s --docnum=1 -o %t1
# RUN: llvm-readelf -h %t1 | FileCheck %s --check-prefix=I386
# RUN: llvm-readelf --file-header %t1 \
# RUN:   | FileCheck %s --strict-whitespace --match-full-lines --check-prefix=I386
# RUN: llvm-readelf --file-headers %t1  \
# RUN:   | FileCheck %s --strict-whitespace --match-full-lines --check-prefix=I386

## Case 3: Use an arbitrary machine type that allows to show how we print Flags.
##         Here we use an EM_MIPS object for that.
