## 0.2.1
* README updates.
## 0.2.0
* added documentation to all public members.
* fix tests incorrectly expecting `lsl #0` in memory operands where it would have no effect
* remove some redundant `a64` operand kinds:
- `RegOffset` is now `RegPreIndex` with no writeback.
- `Offset` was a duplicate of `PCOffset`, and all uses have been so-renamed.
## 0.1.4
* add or fix many a64 instructions, extend support up through armv8.5.
- some disassembly and optional elements of instruction text does not match
the arm manual, but instruction data should be correct across the board.
- SVE and SVE2 are not yet supported, and return `IncompleteDecoder` errors.
## 0.1.3
* same as 0.1.2, but fixes a few compilation warnings that snuck in too.
## 0.1.2
* fix some instructions in aarch64 decoding panicking with "unreachable"
instead of returning an `Err(DecodeError::Incomplete)`. similarly, some
instructions panicked instead of returning `InvalidOpcode` or `InvalidOperand`
as they should.
* fix some instructions in armv7 decoding or display panicking instead of
displaying a valid instruction, or returning a decode error.
... subsequently yanked because some compilation warnings ended up in this version.
## 0.1.1
* fix incorrect `yaxpeax_arch::Arch` impl for `std`-enabled builds
(DecodeError did not implement `std::error::Error` in those build environments)
## 0.1.0
* target yaxpeax-arch 0.2.0
## 0.0.6
* fix incorrect markdown in README.md
## 0.0.5
* add thumb/thumb2 decoders
these decoders are considered "mostly correct" and "mostly complete". notably,
system instructions are less well-tested (particularly `mrs`, `cps`, and
similar), and the NEON extensions are still unsupported. NEON in particular
yield `DecodeError::Incomplete`. if you, the user, see `Incomplete`, that is a
`yaxpeax-arm` error!
`yaxpeax-arm` differs from the ARM manual's assembly syntax in a few ways:
* `.w` suffixes are best-effort.
* `addw`/`subw` are written `add.w`/`sub.w` for consistency with other wide instructions.
* `adr` with added/subtracted offset are shown as `add`/`sub`
* testing is not as exhaustive as is possible for ARM; errors may yet exist
at this time, if-then instructions (`IT`) are decoded, but the decoder has no
notion of "in an `IT` block or not", so following conditional instructions are
not yet conditional.
this all said, for armv4/thumb decoding, the implementation here is probably
close to correct. for armv6+/thumb2, aside from these notes, the implementation
here is ... hopefully ... close to correct.
* add clear rules by which `yaxpeax-arm` will be versioned 0.1 or 1.0. (see README)
## 0.0.4
* bump yaxpeax-arch, no functional change
## 0.0.3
`Instruction`, `Opcode`, and `Operand` are now a useful model of decoded
operations.
* `Operands`, plural, the enum of operands in the instruction, is now gone in
favor of `Operand` that describe one operand of the instruction
* `Instruction` no longer include operand attributes like "add", "index", or "wback"
* better (not quite complete) support for non-user instructions and coprocessor instructions
* instructions operating on status registers through masks are now directly supported
* first brush of arm-version-specific decoder feature selection
* fix several preindex/postindex reversals
## 0.0.2
last revison that's sufficient for disassembly and really nothing else
