/** \defgroup codeobjectmanager Code Object Manager
 *  @{
 *
 * @brief The code object manager is a callable library that provides
 * operations for creating and inspecting code objects.
 *
 * The library provides handles to various objects. Concurrent execution of
 * operations is supported provided all objects accessed by each concurrent
 * operation are disjoint. For example, the @p amd_comgr_data_set_t handles
 * passed to operations must be disjoint, together with all the @p
 * amd_comgr_data_t handles that have been added to it. The exception is that
 * the default device library data object handles can be non-disjoint as they
 * are immutable.
 *
 * The library supports generating and inspecting code objects that
 * contain machine code for a certain set of instruction set
 * arhitectures (isa). The set of isa supported and information about
 * the properties of the isa can be queried.
 *
 * The library supports performing an action that can take data
 * objects of one kind, and generate new data objects of another kind.
 *
 * Data objects are referenced using handles using @p
 * amd_comgr_data_t. The kinds of data objects are given
 * by @p amd_comgr_data_kind_t.
 *
 * To perform an action, two @p amd_comgr_data_set_t
 * objects are created. One is used to hold all the data objects
 * needed by an action, and other is updated by the action with all
 * the result data objects. In addition, an @p
 * amd_comgr_action_info_t is created to hold
 * information that controls the action. These are then passed to @p
 * amd_comgr_do_action to perform an action specified by
 * @p amd_comgr_action_kind_t.
 *
 * Data objects are reference counted and are destroyed when the
 * reference count reaches 0. When a data object is created, its
 * reference count is 1, it has 0 bytes of data, it has an empty name,
 * and it has no metadata.
 *
 * Mutating a data object is only permitted before it is used as part of
 * the input to an action. A data object which is the result of an action
 * must not be mutated.
 *
 * Some data objects can have associated metadata. There are
 * operations for querying this metadata.
 *
 * The default device library that satisfies the requirements of the
 * compiler action can be obtained.
 *
 * The library inspects some environment variables to aid in debugging. These
 * include:
 * - @p AMD_COMGR_SAVE_TEMPS: If this is set, and is not "0", the library does
 *   not delete temporary files generated while executing compilation actions.
 *   These files do not appear in the current working directory, but are
 *   instead left in a platform-specific temporary directory (/tmp on Linux and
 *   C:\Temp or the path found in the TEMP environment variable on Windows).
 * - @p AMD_COMGR_SAVE_LLVM_TEMPS: If this is set, and is not "0", Comgr
 *   forwards "--save-temps=obj" to Clang Driver invocations
 * - @p AMD_COMGR_REDIRECT_LOGS: If this is not set, or is set to "0", logs are
 *   returned to the caller as normal. If this is set to "stdout"/"-" or
 *   "stderr", logs are additionally copied to the standard output or error
 *   stream, respectively. If this is set to any other value, it is interpreted
 *   as a filename which logs are appended to. In all cases logs are still
 *   returned to the caller; this variable copies them, it does not move them.
 *   Logs may be redirected irrespective of whether logging is enabled.
 * - @p AMD_COMGR_EMIT_VERBOSE_LOGS: If this is set, and is not "0", logs will
 *   include additional Comgr-specific informational messages. Equivalent to
 *   AMD_COMGR_LOG_LEVEL=debug, unless AMD_COMGR_LOG_LEVEL is set, which takes
 *   precedence.
 * - @p AMD_COMGR_LOG_LEVEL: Sets the severity threshold of the Comgr logger.
 *   Values from least to most verbose: "none", "error", "warning", "info",
 *   "debug" (case-insensitive). A level enables that severity and all more
 *   severe ones. Takes precedence over AMD_COMGR_EMIT_VERBOSE_LOGS; if unset,
 *   defaults to "debug" when AMD_COMGR_EMIT_VERBOSE_LOGS is enabled, else
 *   "error".

 * @ brief Given a code object and an ELF virtual address, map the ELF virtual
 * address to a code object offset. Also, determine if the ELF virtual address
 * maps to an offset in a data region that is defined by the ELF file, but that
 * does not occupy bytes in the ELF file. This is typically true of offsets that
 * that refer to runtime or heap allocated memory. For ELF files with defined
 * sections, these data regions are referred to as NOBITS or .bss sections.
 *
 * @param[in] data The data object to be inspected for the given ELF virtual
 * address. This should be of kind AMD_COMGR_DATA_KIND_EXECUTABLE.
 *
 * @param[in] elf_virtual_address The address used to calculate the code object
 * offset.
 *
 * @param[out] code_object_offset The code object offset returned to the caller
 * based on the given ELF virtual address.
 *
 * @param[out] slice_size For nobits regions: the size in bytes, starting from
 * the provided virtual address up to the end of the segment. In this case, the
 * slice size represents the number of contiguous unreadable addresses following
 * the provided address.

 * For bits regions: the size in bytes, starting from the provided virtual
 * address up to either the end of the segment, or the start of a NOBITS region.
 * In this case, slice size represents the number of contiguous readable
 * addresses following the provided address.
 *
 * @param[out] nobits Set to true if the code object offset points to a location
 * in a data region that does not occupy bytes in the ELF file, as described
 * above.
 *
 * @retval ::AMD_COMGR_STATUS_SUCCESS The function has been executed
 * successfully.
 *
 * @retval ::AMD_COMGR_STATUS_ERROR The provided code object has an invalid
 * header due to a mismatch in magic, class, data, version, abi, type, or
 * machine.
 *
 * @retval ::AMD_COMGR_STATUS_ERROR_INVALID_ARGUMENT @p data is not of
 * kind AMD_COMGR_DATA_KIND_EXECUTABLE or invalid, or that the provided @p
 * elf_virtual_address is not within the ranges covered by the object's
 * load-type program headers.

/**
 * @brief Rewrite a code object from one ISA to another.
 *
 * Rewrites GPU instructions in the ELF code object so that it can execute
 * on a different target ISA. This includes both same-family stepping
 * patches (e.g. B0 to A0) and cross-family transpilation.
 * The input ELF is not modified; a new data object is created and returned.
 *
 * If no patches are needed, the output is a copy of the input.
 *
 * Currently supported transformations:
 *   - GFX1250 B0 to A0
 *
 * Additional source/target ISA pairs may be added in future releases.
 * Unsupported @p source_isa_name / @p target_isa_name combinations return
 * @c AMD_COMGR_STATUS_ERROR_INVALID_ARGUMENT.
 *
 * @param[in] input A data object of kind @p AMD_COMGR_DATA_KIND_EXECUTABLE
 *   containing the input ELF code object bytes.
 * @param[in] source_isa_name A null terminated string that is the isa name
 *   the code object was compiled for. The isa name is defined as the Code
 *   Object Target Identification string, described at
 *   https://llvm.org/docs/AMDGPUUsage.html#code-object-target-identification
 * @param[in] target_isa_name A null terminated string that is the isa name
 *   of the target GPU.
 * @param[out] output A handle to a data object of kind @p
 *   AMD_COMGR_DATA_KIND_EXECUTABLE containing the rewritten ELF. The caller
 *   must release this handle using @c amd_comgr_release_data when done.
 *   @p output is not modified on failure.
 *
 * @retval ::AMD_COMGR_STATUS_SUCCESS Patching completed successfully.
 * @retval ::AMD_COMGR_STATUS_ERROR An internal error occurred.
 * @retval ::AMD_COMGR_STATUS_ERROR_INVALID_ARGUMENT @p input is an invalid
 *   data object, is not of kind @p AMD_COMGR_DATA_KIND_EXECUTABLE, does not
 *   contain data bytes, or @p source_isa_name or @p target_isa_name is NULL,
 *   or the source/target isa name combination is not supported.
 * @retval ::AMD_COMGR_STATUS_ERROR_OUT_OF_RESOURCES Unable to allocate
 *   the output data object.
