// REQUIRES: comgr-has-spirv-translator

// COM: Build a compressed bitcode bundle for amdgcnspirv.
// COM: --offload-new-driver: SPIR-V bundling needs the new driver (old-driver
// COM: default lines bundle raw bitcode and fail the SPV check).
// RUN: %clang -c -x hip --offload-arch=amdgcnspirv \
// RUN:    -nogpulib -nogpuinc -emit-llvm \
// RUN:    --gpu-bundle-output --offload-device-only --offload-new-driver \
// RUN:    --offload-compress \
// RUN:    %s -o %t.compressed-bundle.bc

// COM: Sanity-check that the bundle is actually compressed (CCOB magic) and
// COM: that the expected entry ID is present.

// MAGIC: C C O B
// ENTRY: hip-spirv64-amd-amdhsa--amdgcnspirv

// COM: Extract the amdgcnspirv entry through Comgr. Output is a SPIR-V module
// COM: (not LLVM bitcode), so verify the SPIR-V magic word 0x07230203.

// SPV: 07230203

// COM: Translate the unbundled SPIR-V back to LLVM IR via Comgr's translator
// COM: and verify it matches the original device source.
