Replaced `BaseAddresses::set_data` with `set_got`.
You should now use the same `BaseAddresses` value for parsing both
`.eh_frame` and `.eh_frame_hdr`.
[#351](https://github.com/gimli-rs/gimli/pull/351)
* Renamed many types and functions related to `.debug_line`.
Renamed `LineNumberProgram` to `LineProgram`.
Renamed `IncompleteLineNumberProgram` to `IncompleteLineProgram`.
Renamed `CompleteLineNumberProgram` to `CompleteLineProgram`.
Renamed `LineNumberProgramHeader` to `LineProgramHeader`.
Renamed `LineNumberRow` to `LineRow`.
Renamed `StateMachine` to `LineRows`.
Renamed `Opcode` to `LineInstruction`.
Renamed `OpcodesIter` to `LineInstructions`.
Renamed `LineNumberSequence` to `LineSequence`.
[#359](https://github.com/gimli-rs/gimli/pull/359)
* Added `Offset` type parameter to `AttributeValue`, `LineProgram`,
`IncompleteLineProgram`, `CompleteLineProgram`, `LineRows`, `LineInstruction`,
and `FileEntry`.
[#324](https://github.com/gimli-rs/gimli/pull/324)
* Changed `FileEntry::path_name`, `FileEntry::directory`, and
`LineProgramHeader::directory` to return an `AttributeValue` instead
of a `Reader`.
[#366](https://github.com/gimli-rs/gimli/pull/366)
* Renamed `FileEntry::last_modification` to `FileEntry::timestamp`
and renamed `FileEntry::length` to `FileEntry::size`.
[#366](https://github.com/gimli-rs/gimli/pull/366)
* Added an `Encoding` type. Changed many functions that previously accepted
`Format`, version or address size parameters to accept an `Encoding`
parameter instead.
Notable changes are `LocationLists::locations`, `RangeLists::ranges`,
and `Expression::evaluation`.
[#364](https://github.com/gimli-rs/gimli/pull/364)
* Changed return type of `LocationLists::new` and `RangeLists::new`.
[#370](https://github.com/gimli-rs/gimli/pull/370)
* Added parameters to `LocationsLists::locations` and `RangeLists::ranges`
to support `.debug_addr`.
[#358](https://github.com/gimli-rs/gimli/pull/358)
* Added more `AttributeValue` variants: `DebugAddrBase`, `DebugAddrIndex`,
`DebugLocListsBase`, `DebugLocListsIndex`, `DebugRngListsBase`, `DebugRngListsIndex`,
`DebugStrOffsetsBase`, `DebugStrOffsetsIndex`, `DebugLineStrRef`.
[#358](https://github.com/gimli-rs/gimli/pull/358)
* Changed `AttributeValue::Data*` attributes to native endian integers instead
of byte arrays.
[#365](https://github.com/gimli-rs/gimli/pull/365)
* Replaced `EvaluationResult::TextBase` with
`EvaluationResult::RequiresRelocatedAddress`. The handling of `TextBase`
was incorrect.
[#335](https://github.com/gimli-rs/gimli/pull/335)
* Added `EvaluationResult::IndexedAddress` for operations that require an
address from `.debug_addr`.
[#358](https://github.com/gimli-rs/gimli/pull/358)
* Added `Reader::read_slice`. Added a default implementation of
`Reader::read_u8_array` which uses this.
[#358](https://github.com/gimli-rs/gimli/pull/358)
### Added
* Added initial support for writing DWARF. This is targeted at supporting
line number information only.
[#340](https://github.com/gimli-rs/gimli/pull/340)
[#344](https://github.com/gimli-rs/gimli/pull/344)
[#346](https://github.com/gimli-rs/gimli/pull/346)
[#361](https://github.com/gimli-rs/gimli/pull/361)
[#362](https://github.com/gimli-rs/gimli/pull/362)
[#365](https://github.com/gimli-rs/gimli/pull/365)
[#368](https://github.com/gimli-rs/gimli/pull/368)
[#382](https://github.com/gimli-rs/gimli/pull/382)
* Added `read` and `write` Cargo features. Both are enabled by default.
[#343](https://github.com/gimli-rs/gimli/pull/343)
* Added support for reading DWARF 5 `.debug_line` and `.debug_line_str` sections.
[#366](https://github.com/gimli-rs/gimli/pull/366)
* Added support for reading DWARF 5 `.debug_str_offsets` sections, including
parsing `DW_FORM_strx*` attributes.
[#358](https://github.com/gimli-rs/gimli/pull/358)
* Added support for reading DWARF 5 `.debug_addr` sections, including parsing
`DW_FORM_addrx*` attributes and evaluating `DW_OP_addrx` and `DW_OP_constx`
operations.
[#358](https://github.com/gimli-rs/gimli/pull/358)
* Added support for reading DWARF 5 indexed addresses and offsets in
`.debug_loclists` and `.debug_rnglists`, including parsing `DW_FORM_rnglistx`
and `DW_FORM_loclistx` attributes.
[#358](https://github.com/gimli-rs/gimli/pull/358)
* Added high level `Dwarf` and `Unit` types. Existing code does not need to
switch to using these types, but doing so will make DWARF 5 support simpler.
[#352](https://github.com/gimli-rs/gimli/pull/352)
[#380](https://github.com/gimli-rs/gimli/pull/380)
[#381](https://github.com/gimli-rs/gimli/pull/381)
* Added `EhFrame::set_address_size` and `DebugFrame::set_address_size` methods
to allow parsing non-native CFI sections. The default address size is still
the native size.
[#325](https://github.com/gimli-rs/gimli/pull/325)
* Added architecture specific definitions for `Register` values and names.
Changed dwarfdump to print them.
[#328](https://github.com/gimli-rs/gimli/pull/328)
* Added support for reading relocatable DWARF sections.
[#337](https://github.com/gimli-rs/gimli/pull/337)
* Added parsing of `DW_FORM_data16`.
[#366](https://github.com/gimli-rs/gimli/pull/366)
### Fixed
* Fixed parsing DWARF 5 ranges with `start == end == 0`.
[#323](https://github.com/gimli-rs/gimli/pull/323)
* Changed `LineRows` to be covariant in its `Reader` type parameter.
[#324](https://github.com/gimli-rs/gimli/pull/324)
* Fixed handling of empty units in dwarfdump.
[#330](https://github.com/gimli-rs/gimli/pull/330)

[#342](https://github.com/gimli-rs/gimli/pull/342)
* Fixed parsing of `DW_CFA_set_loc`.
[#355](https://github.com/gimli-rs/gimli/pull/355)
* Fixed handling of multiple headers in `.debug_loclists` and `.debug_rnglists`.
[#370](https://github.com/gimli-rs/gimli/pull/370)

--------------------------------------------------------------------------------
## 0.16.0
Released 2018/06/01.
### Added
* Added support for building in `#![no_std]` environments, when the `alloc`
crate is available. Disable the "std" feature and enable the "alloc"
feature. [#138][] [#271][]
* Added support for DWARF 5 `.debug_rnglists` and `.debug_loclists`
sections. [#272][]
* Added support for DWARF 5 `DW_FORM_ref_sup` and `DW_FORM_strp_sup` attribute
forms. [#288][]
* Added support for DWARF 5 operations on typed values. [#293][]
* A `dwarf-validate` example program that checks the integrity of the given
DWARF and its references between sections. [#290][]
* Added the `EndianReader<T>` type, an easy way to define a custom `Reader`
implementation with a reference to a generic buffer of bytes and an associated
endianity. [#298][] [#302][]
### Changed
* Various speed improvements for evaluating `.debug_line` line number
programs. [#276][]
* The example `dwarfdump` clone is a [whole lot faster
now][dwarfdump-faster]. [#282][] [#284][] [#285][]
### Deprecated
* `EndianBuf` has been renamed to `EndianSlice`, use that name instead. [#295][]
### Fixed
* Evaluating the `DW_CFA_restore_state` opcode properly maintains the current
location. Previously it would incorrectly restore the old location when
popping from evaluation stack. [#274][]

## 0.15.0
Released 2017/12/01.
### Added
* Added the `EndianBuf::to_string()` method. [#233][]
* Added more robust error handling in our example `dwarfdump` clone. [#234][]
* Added `FrameDescriptionEntry::initial_address` method. [#237][]
* Added `FrameDescriptionEntry::len` method. [#237][]
* Added the `FrameDescriptionEntry::entry_len` method. [#241][]
* Added the `CommonInformationEntry::offset` method. [#241][]
* Added the `CommonInformationEntry::entry_len` method. [#241][]
* Added the `CommonInformationEntry::version` method. [#241][]
* Added the `CommonInformationEntry::augmentation` method. [#241][]
* Added the `CommonInformationEntry::code_alignment_factor` method. [#241][]
* Added the `CommonInformationEntry::data_alignment_factor` method. [#241][]
* Added the `CommonInformationEntry::return_address_register` method. [#241][]
* Added support for printing `.eh_frame` sections to our example `dwarfdump`
clone. [#241][]
* Added support for parsing the `.eh_frame_hdr` section. On Linux, the
`.eh_frame_hdr` section provides a pointer to the already-mapped-in-memory
`.eh_frame` data, so that it doesn't need to be duplicated, and a binary
search table of its entries for faster unwinding information lookups. [#250][]
* Added support for parsing DWARF 5 compilation unit headers. [#257][]
* Added support for DWARF 5's `DW_FORM_implicit_const`. [#257][]
### Changed
* Unwinding methods now give ownership of the unwinding context back to the
caller if errors are encountered, not just on the success path. This allows
recovering from errors in signal-safe code, where constructing a new unwinding
context is not an option because it requires allocation. This is a **breaking
change** affecting `UnwindSection::unwind_info_for_address` and
`UninitializedUnwindContext::initialize`. [#241][]
* `CfaRule` and `RegisterRule` now expose their `DW_OP` expressions as
`Expression`. This is a minor **breaking change**. [#241][]
* The `Error::UnknownVersion` variant now contains the unknown version
number. This is a minor **breaking change**. [#245][]
* `EvaluationResult::RequiresEntryValue` requires an `Expression` instead of a
`Reader` now. This is a minor **breaking change**. [#256][]

--------------------------------------------------------------------------------
## 0.14.0
Released 2017/08/08.
### Added
* All `pub` types now `derive(Hash)`. [#192][]
* All the constants from DWARF 5 are now defined. [#193][]
* Added support for the `DW_OP_GNU_parameter_ref` GNU extension to parsing and
evaluation DWARF opcodes. [#208][]
* Improved LEB128 parsing performance. [#216][]
* Improved `.debug_{aranges,pubnames,pubtypes}` parsing performance. [#218][]
* Added the ability to choose endianity dynamically at run time, rather than
only statically at compile time. [#219][]
### Changed
* The biggest change of this release is that `gimli` no longer requires the
object file's section be fully loaded into memory. This enables using `gimli`
on 32 bit platforms where there often isn't enough contiguous virtual memory
address space to load debugging information into. The default behavior is
still geared for 64 bit platforms, where address space overfloweth, and you
can still load the whole sections of the object file (or the entire object
file) into memory. This is abstracted over with the `gimli::Reader`
trait. This manifests as small (but many) breaking changes to much of the
public API. [#182][]
### Fixed
* The `DW_END_*` constants for defining endianity of a compilation unit were
previously incorrect. [#193][]
* The `DW_OP_addr` opcode is relative to the base address of the `.text` section
of the binary, but we were incorrectly treating it as an absolute value. [#210][]
