-// is undefined and save a little bit more space and do a little fewer
-// comparisons that way.
-//
-// The maximum number of rules preallocated by libunwind is 97 for AArch64, 128
-// for ARM, and even 188 for MIPS. It is extremely unlikely to encounter this
-// many register rules in practice.

-/// An easy way to define a custom `Reader` implementation with a reference to a
-/// generic buffer of bytes and an associated endianity.
-///
-/// Note that the whole original buffer is kept alive in memory even if there is
-/// only one reader that references only a handful of bytes from that original
-/// buffer. That is, `EndianReader` will not do any copying, moving, or
-/// compacting in order to free up unused regions of the original buffer. If you
-/// require this kind of behavior, it is up to you to implement `Reader`
-/// directly by-hand.
-///
-/// # Example
-///
-/// Say you have an `mmap`ed file that you want to serve as a `gimli::Reader`.
-/// You can wrap that `mmap`ed file up in a `MmapFile` type and use
-/// `EndianReader<Rc<MmapFile>>` or `EndianReader<Arc<MmapFile>>` as readers as
-/// long as `MmapFile` dereferences to the underlying `[u8]` data.
-///
-/// ```

-/// use std::ops::Deref;
-/// use std::path::Path;
-/// use std::slice;
-/// use std::sync::Arc;
-///
-/// /// A type that represents an `mmap`ed file.

-///         // Call `mmap` and check for errors and all that...
-/// #       unimplemented!()
-///     }
-/// }
-///
-/// impl Drop for MmapFile {

-///         // Call `munmap` to clean up after ourselves...
-/// #       unimplemented!()
-///     }
-/// }
-///
-/// // And `MmapFile` can deref to a slice of the `mmap`ed region of memory.
-/// impl Deref for MmapFile {

-//!         }
-//!     }
-//! }
-//! # unreachable!()
-//! # }
-//! ```
-//!
-//! Full example programs:
-//!
-//!   * [A simple parser](https://github.com/gimli-rs/gimli/blob/master/crates/examples/src/bin/simple.rs)
-//!
-//!   * [A `dwarfdump`
-//!     clone](https://github.com/gimli-rs/gimli/blob/master/crates/examples/src/bin/dwarfdump.rs)
-//!
-//!   * [An `addr2line` clone](https://github.com/gimli-rs/addr2line)
-//!
-//!   * [`ddbug`](https://github.com/gimli-rs/ddbug), a utility giving insight into
-//!     code generation by making debugging information readable

-//!     executable (via `DW_AT_producer`)
-//!
-//!   * [`dwarf-validate`](https://github.com/gimli-rs/gimli/blob/master/crates/examples/src/bin/dwarf-validate.rs),
-//!     a program to validate the integrity of some DWARF and its references
-//!     between sections and compilation units.
-//!
-//! ## API Structure
-//!
-//! * Basic familiarity with DWARF is assumed.
-//!
-//! * The [`Dwarf`](./struct.Dwarf.html) type contains the commonly used DWARF
-//! sections. It has methods that simplify access to debugging data that spans
-//! multiple sections. Use of this type is optional, but recommended.
-//!
-//! * Each section gets its own type. Consider these types the entry points to
-//! the library:
-//!
-//!   * [`DebugAbbrev`](./struct.DebugAbbrev.html): The `.debug_abbrev` section.
-//!
-//!   * [`DebugAddr`](./struct.DebugAddr.html): The `.debug_addr` section.
-//!
-//!   * [`DebugAranges`](./struct.DebugAranges.html): The `.debug_aranges`
-//!   section.
-//!
-//!   * [`DebugFrame`](./struct.DebugFrame.html): The `.debug_frame` section.
-//!
-//!   * [`DebugInfo`](./struct.DebugInfo.html): The `.debug_info` section.
-//!
-//!   * [`DebugLine`](./struct.DebugLine.html): The `.debug_line` section.
-//!
-//!   * [`DebugLineStr`](./struct.DebugLineStr.html): The `.debug_line_str` section.
-//!
-//!   * [`DebugLoc`](./struct.DebugLoc.html): The `.debug_loc` section.
-//!
-//!   * [`DebugLocLists`](./struct.DebugLocLists.html): The `.debug_loclists` section.
-//!
-//!   * [`DebugPubNames`](./struct.DebugPubNames.html): The `.debug_pubnames`
-//!   section.
-//!
-//!   * [`DebugPubTypes`](./struct.DebugPubTypes.html): The `.debug_pubtypes`
-//!   section.
-//!
-//!   * [`DebugRanges`](./struct.DebugRanges.html): The `.debug_ranges` section.
-//!
-//!   * [`DebugRngLists`](./struct.DebugRngLists.html): The `.debug_rnglists` section.
-//!
-//!   * [`DebugStr`](./struct.DebugStr.html): The `.debug_str` section.
-//!
-//!   * [`DebugStrOffsets`](./struct.DebugStrOffsets.html): The `.debug_str_offsets` section.
-//!
-//!   * [`DebugTypes`](./struct.DebugTypes.html): The `.debug_types` section.
-//!
-//!   * [`DebugCuIndex`](./struct.DebugCuIndex.html): The `.debug_cu_index` section.
-//!
-//!   * [`DebugTuIndex`](./struct.DebugTuIndex.html): The `.debug_tu_index` section.
-//!
-//!   * [`EhFrame`](./struct.EhFrame.html): The `.eh_frame` section.
-//!
-//!   * [`EhFrameHdr`](./struct.EhFrameHdr.html): The `.eh_frame_hdr` section.
-//!
-//! * Each section type exposes methods for accessing the debugging data encoded
-//! in that section. For example, the [`DebugInfo`](./struct.DebugInfo.html)
-//! struct has the [`units`](./struct.DebugInfo.html#method.units) method for
-//! iterating over the compilation units defined within it.
-//!
-//! * Offsets into a section are strongly typed: an offset into `.debug_info` is
-//! the [`DebugInfoOffset`](./struct.DebugInfoOffset.html) type. It cannot be
-//! used to index into the [`DebugLine`](./struct.DebugLine.html) type because
-//! `DebugLine` represents the `.debug_line` section. There are similar types
-//! for offsets relative to a compilation unit rather than a section.
-//!
-//! ## Using with `FallibleIterator`
-//!
-//! The standard library's `Iterator` trait and related APIs do not play well
-//! with iterators where the `next` operation is fallible. One can make the
-//! `Iterator`'s associated `Item` type be a `Result<T, E>`, however the
-//! provided methods cannot gracefully handle the case when an `Err` is
-//! returned.
-//!
-//! This situation led to the
-//! [`fallible-iterator`](https://crates.io/crates/fallible-iterator) crate's
-//! existence. You can read more of the rationale for its existence in its
-//! docs. The crate provides the helpers you have come to expect (eg `map`,
-//! `filter`, etc) for iterators that can fail.
-//!
-//! `gimli`'s many lazy parsing iterators are a perfect match for the
-//! `fallible-iterator` crate's `FallibleIterator` trait because parsing is not
-//! done eagerly. Parse errors later in the input might only be discovered after
-//! having iterated through many items.
-//!
-//! To use `gimli` iterators with `FallibleIterator`, import the crate and trait
-//! into your code:
-//!
-//! ```
-//! # #[cfg(feature = "fallible-iterator")]
-//! # fn foo() {
-//! // Use the `FallibleIterator` trait so its methods are in scope!
-//! use fallible_iterator::FallibleIterator;
-//! use gimli::{DebugAranges, EndianSlice, LittleEndian};
-//!
-//! fn find_sum_of_address_range_lengths(aranges: DebugAranges<EndianSlice<LittleEndian>>)
-//!     -> gimli::Result<u64>
-//! {
-//!     // `DebugAranges::headers` returns a `FallibleIterator`!
-//!     aranges.headers()
-//!         // `flat_map` is provided by `FallibleIterator`!
-//!         .flat_map(|header| Ok(header.entries()))
-//!         // `map` is provided by `FallibleIterator`!
-//!         .map(|arange| Ok(arange.length()))
-//!         // `fold` is provided by `FallibleIterator`!
-//!         .fold(0, |sum, len| Ok(sum + len))
-//! }
-//! # }
-//! # fn main() {}

-/// A DWARF expression evaluator.

-/// # Usage
-/// A DWARF expression may require additional data to produce a final result,
-/// such as the value of a register or a memory location.  Once initial setup
-/// is complete (i.e. `set_initial_value()`, `set_object_address()`) the
-/// consumer calls the `evaluate()` method.  That returns an `EvaluationResult`,
-/// which is either `EvaluationResult::Complete` or a value indicating what
-/// data is needed to resume the `Evaluation`.  The consumer is responsible for
-/// producing that data and resuming the computation with the correct method,
-/// as documented for `EvaluationResult`.  Only once an `EvaluationResult::Complete`
-/// is returned can the consumer call `result()`.
-///
-/// This design allows the consumer of `Evaluation` to decide how and when to
-/// produce the required data and resume the computation.  The `Evaluation` can
-/// be driven synchronously (as shown below) or by some asynchronous mechanism
-/// such as futures.
-///
-/// # Examples
-/// ```rust,no_run
-/// use gimli::{Evaluation, EvaluationResult, Expression};
-/// # let bytecode = gimli::EndianSlice::new(&[], gimli::LittleEndian);
-/// # let encoding = unimplemented!();
-/// # let get_register_value = |_, _| gimli::Value::Generic(42);

-/// A trait for reading the data from a DWARF section.
-///
-/// All read operations advance the section offset of the reader
-/// unless specified otherwise.
-///
-/// ## Choosing a `Reader` Implementation
-///
-/// `gimli` comes with a few different `Reader` implementations and lets you
-/// choose the one that is right for your use case. A `Reader` is essentially a
-/// view into the raw bytes that make up some DWARF, but this view might borrow
-/// the underlying data or use reference counting ownership, and it might be
-/// thread safe or not.
-///
-/// | Implementation    | Ownership         | Thread Safe | Notes |
-/// |:------------------|:------------------|:------------|:------|
-/// | [`EndianSlice`](./struct.EndianSlice.html)        | Borrowed          | Yes         | Fastest, but requires that all of your code work with borrows. |
-/// | [`EndianRcSlice`](./struct.EndianRcSlice.html)    | Reference counted | No          | Shared ownership via reference counting, which alleviates the borrow restrictions of `EndianSlice` but imposes reference counting increments and decrements. Cannot be sent across threads, because the reference count is not atomic. |
-/// | [`EndianArcSlice`](./struct.EndianArcSlice.html)  | Reference counted | Yes         | The same as `EndianRcSlice`, but uses atomic reference counting, and therefore reference counting operations are slower but `EndianArcSlice`s may be sent across threads. |
-/// | [`EndianReader<T>`](./struct.EndianReader.html)   | Same as `T`       | Same as `T` | Escape hatch for easily defining your own type of `Reader`. |

-/// A raw reader of the data that defines the Debugging Information Entries.
-///
-/// `EntriesRaw` provides primitives to read the components of Debugging Information
-/// Entries (DIEs). A DIE consists of an abbreviation code (read with `read_abbreviation`)
-/// followed by a number of attributes (read with `read_attribute`).
-/// The user must provide the control flow to read these correctly.
-/// In particular, all attributes must always be read before reading another
-/// abbreviation code.
-///
-/// `EntriesRaw` lacks some features of `EntriesCursor`, such as the ability to skip
-/// to the next sibling DIE. However, this also allows it to optimize better, since it
-/// does not need to perform the extra bookkeeping required to support these features,
-/// and thus it is suitable for cases where performance is important.
-///
-/// ## Example Usage
-/// ```rust,no_run
-/// # fn example() -> Result<(), gimli::Error> {
-/// # let debug_info = gimli::DebugInfo::new(&[], gimli::LittleEndian);
-/// # let get_some_unit = || debug_info.units().next().unwrap().unwrap();
-/// let unit = get_some_unit();
-/// # let debug_abbrev = gimli::DebugAbbrev::new(&[], gimli::LittleEndian);
-/// # let get_abbrevs_for_unit = |_| unit.abbreviations(&debug_abbrev).unwrap();
-/// let abbrevs = get_abbrevs_for_unit(&unit);
-///
-/// let mut entries = unit.entries_raw(&abbrevs, None)?;
-/// while !entries.is_empty() {
-///     let abbrev = if let Some(abbrev) = entries.read_abbreviation()? {
-///         abbrev
-///     } else {
-///         // Null entry with no attributes.
-///         continue
-///     };
-///     match abbrev.tag() {
-///         gimli::DW_TAG_subprogram => {
-///             // Loop over attributes for DIEs we care about.
-///             for spec in abbrev.attributes() {
-///                 let attr = entries.read_attribute(*spec)?;
-///                 match attr.name() {
-///                     // Handle attributes.
