The patch adds ELF notes into SHT_NOTE sections of ELF offload images passed to clang-offload-wrapper. The new notes use a null-terminated "LLVMOMPOFFLOAD" note name. There are currently three types of notes: VERSION: a string (not null-terminated) representing the ELF offload image structure. The current version '1.0' does not put any restrictions on the structure of the image. If we ever need to come up with a common structure for ELF offload images (e.g. to be able to analyze the images in libomptarget in some standard way), then we will introduce new versions. PRODUCER: a vendor specific name of the producing toolchain. Upstream LLVM uses "LLVM" (not null-terminated). PRODUCER_VERSION: a vendor specific version of the producing toolchain. Upstream LLVM uses LLVM_VERSION_STRING with optional <space> LLVM_REVISION. All three notes are not mandatory currently. Differential Revision: https://reviews.llvm.org/D99551
