// CHECK-HELP: OVERVIEW:
// CHECK-HELP: A utility to extract all the target images from a
// CHECK-HELP: linked fat binary, and store them in separate files.
// CHECK-HELP: USAGE: clang-offload-extract [options] <input file>
// CHECK-HELP: OPTIONS:
// CHECK-HELP: Generic Options:
// CHECK-HELP:   --help          - Display available options (--help-hidden for more)
// CHECK-HELP:   --help-list     - Display list of available options (--help-list-hidden for more)
// CHECK-HELP:   --version       - Display the version of this program
// CHECK-HELP: Utility-specific options:
// CHECK-HELP:   --stem=<string> - Specifies the stem for the output file(s).
// CHECK-HELP:                     The default stem when not specified is "target.bin".
// CHECK-HELP:                     The Output file name is composed from this stem and
// CHECK-HELP:                     the sequential number of each extracted image appended
// CHECK-HELP:                     to the stem:
// CHECK-HELP:                       <stem>.<index>

//
// Create fat offload binary with two embedded target images.
//
// RUN: echo 'Target image 1' > %t.bin0
// RUN: echo 'Target image 2' > %t.bin1
// RUN: clang-offload-wrapper -kind=openmp -target=tg0 %t.bin0 -kind=sycl -target=tg1 %t.bin1 -o %t.wrapped.bc
// RUN: %clang -fdeclspec %s %t.wrapped.bc -o %t.fat.bin

//
// Extract target images (deprecated use model)
//
// RUN: clang-offload-extract --output=%t.deprecated %t.fat.bin | FileCheck %s --check-prefix CHECK-DEPRECATE
// CHECK-DEPRECATE: Section {{.*}}: Image 1'-> File
// CHECK-DEPRECATE: Section {{.*}}: Image 2'-> File

//
// Check that extracted contents match the original images.
//
// RUN: diff %t.deprecated.0 %t.bin0
// RUN: diff %t.deprecated.1 %t.bin1

//
// Extract target images (new use model)
//
// RUN: clang-offload-extract --stem=%t.extracted %t.fat.bin | FileCheck %s --check-prefix CHECK-EXTRACT
// CHECK-EXTRACT: Section {{.*}}: Image 1'-> File
// CHECK-EXTRACT: Section {{.*}}: Image 2'-> File

//
// Check that extracted contents match the original images.
//
// RUN: diff %t.extracted.0 %t.bin0
// RUN: diff %t.extracted.1 %t.bin1
//
// Some code so that we can build an offload executable from this file.
