## Regression test for a magic-byte collision in the compressed offload bundle
## (CCOB) reader used by --offloading (llvm::object::extractOffloadBundle).
##
## The reader used to find the boundary between concatenated bundles by scanning
## for the literal 4-byte magic "CCOB". Those bytes can appear by chance inside a
## compressed payload, which truncated a valid single bundle so it failed to
## decompress. The .hip_fatbin below is a single compressed bundle whose
## compressed region embeds the bytes "CCOB" inside a zstd skippable frame
## (ignored by the decompressor); a reader that advances by the header's FileSize
## handles it correctly. Regenerate the bundle with
## clang/test/Driver/Inputs/clang-offload-bundler-magic-collision.py.
