// Note: The following tests check that a spv.target_env can properly control
// the conversion target and filter unavailable ops during the conversion.
// We don't care about the op argument consistency too much; so certain enum
// values for enum attributes may not make much sense for the test op.

// spv.AtomicCompareExchangeWeak is available from SPIR-V 1.0 to 1.3 under
// Kernel capability.
// spv.AtomicCompareExchangeWeak has two memory semantics enum attribute,
// whose value, if containing AtomicCounterMemory bit, additionally requires
// AtomicStorage capability.

// spv.BitReverse is available in all SPIR-V versions under Shader capability.

// spv.GroupNonUniformBallot is available starting from SPIR-V 1.3 under
// GroupNonUniform capability.

// spv.SubgroupBallotKHR is available under in all SPIR-V versions under
// SubgroupBallotKHR capability and SPV_KHR_shader_ballot extension.

// The GeometryPointSize capability implies the Geometry capability, which
// implies the Shader capability.

// PhysicalStorageBuffer64 addressing model is available via extension
// SPV_EXT_physical_storage_buffer or SPV_KHR_physical_storage_buffer;
// both extensions are incorporated into SPIR-V 1.5.

// Vulkan memory model is available via extension SPV_KHR_vulkan_memory_model,
// which extensions are incorporated into SPIR-V 1.5.
