================ Comment at: clang/docs/ClangOffloadBinary.rst:15 +metadata. We use a custom binary format for bundling all the device images +together. The image format is a small header wrapping around a string map. This +tool creates bundled binaries so that they can be embedded into the host to ---------------- It would help if more details are given, e.g, offset and size of members of the header and layout of the string map. ================ Comment at: clang/test/Frontend/embed-object.c:3 -// CHECK: @[[OBJECT:.+]] = private constant [120 x i8] c"\10\FF\10\AD{{.*}}", section ".llvm.offloading", align 8 +// CHECK: @[[OBJECT:.+]] = private constant [0 x i8] zeroinitializer, section ".llvm.offloading", align 8 // CHECK: @llvm.compiler.used = appending global [1 x ptr] [ptr @[[OBJECT]]], section "llvm.metadata" ---------------- Is this due to the embedded object being empty? So now the bitcode for different targets are bundled by clang-offload-packager then embedded as one file in the relocatable object file? In the old scheme the bitcode for different targets are bundled by clang-offload-bundler then embedded in the relocatable object file, right? What's the advantage of clang-offload-packager compared with clang-offload-bundler?
