// CHECK-HELP: {{.*}}OVERVIEW: A tool to create a wrapper bitcode for offload target binaries. Takes offload
|
|
// CHECK-HELP: {{.*}}target binaries as input and produces bitcode file containing target binaries packaged
|
|
// CHECK-HELP: {{.*}}as data and initialization code which registers target binaries in offload runtime.
|
|
// CHECK-HELP: {{.*}}USAGE: clang-offload-wrapper [options] <input files>
|
|
// CHECK-HELP: {{.*}} -o=<filename> - Output filename
|
|
// CHECK-HELP: {{.*}} --target=<triple> - Target triple for the output module
|
|
|
|
//
|
|
// Generate a file to wrap.
