This file details the changelog of Capstone. |
|
|
|
--------------------------------- |
|
Version 2.1 |
|
|
|
[ API changes ] |
|
|
|
- API version has been bumped to 2.1. |
|
- Change prototype of cs_close() to be able to invalidate closed handle. |
|
See http://capstone-engine.org/version_2.1_API.html for more information. |
|
- Extend cs_support() to handle more query types, not only about supported |
|
architectures. This change is backward compatible, however, so existent code |
|
do not need to be modified to support this. |
|
- New query type CS_SUPPORT_DIET for cs_support() to ask about diet status of |
|
the engine. |
|
- New error code CS_ERR_DIET to report errors about newly added diet mode. |
|
- New error code CS_ERR_VERSION to report issue of incompatible versions between |
|
bindings & core engine. |
|
|
|
|
|
[ Core changes ] |
|
|
|
- On memory usage, Capstone uses about 40% less memory, while still faster |
|
than version 2.0. |
|
- All architectures are much smaller: binaries size reduce at least 30%. |
|
Especially, X86-only binary reduces from 1.9MB to just 720KB. |
|
- Support "diet" mode, in which engine size is further reduced (by around 40%) |
|
for embedding purpose. The price to pay is that we have to sacrifice some |
|
non-critical data fields. See http://capstone-engine.org/diet.html for more |
|
details. |
|
|
|
|
|
[ Architectures ] |
|
|
|
- Update all 5 architectures to fix bugs. |
|
- PowerPC: |
|
- New instructions: FMR & MSYNC. |
|
- Mips: |
|
- New instruction: DLSA |
|
- X86: |
|
- Properly handle AVX-512 instructions. |
|
- New instructions: PSETPM, SALC, INT1, GETSEC. |
|
- Fix some memory leaking issues in case of prefixed instructions such |
|
as LOCK, REP, REPNE. |
|
|
|
|
|
[ Python binding ] |
|
|
|
- Verify the core version at initialization time. Refuse to run if its version |
|
is different from the core's version. |
|
- New API disasm_lite() added to Cs class. This light API only returns tuples of |
|
(address, size, mnemonic, op_str), rather than list of CsInsn objects. This |
|
improves performance by around 30% in some benchmarks. |
|
- New API cs_version_bind() returns binding's version, which might |
|
differ from the core's API version if binding is out-of-date. |
|
- Fixed some memory leaking bugs for Cython binding. |
|
- Fix a bug crashing Cython code when accessing @regs_read/regs_write/groups. |
|
- Support diet mode. |
|
|
|
|
|
[ Java binding ] |
|
|
|
- Fix some memory leaking bugs. |
|
- New API version() returns combined version. |
|
- Support diet mode. |
|
- Better support for detail option. |
|
|
|
|
|
[ Miscellaneous ] |
|
|
|
- make.sh now can uninstall the core engine. This is done with: |
|
|
|
$ sudo ./make.sh uninstall |
|
|
|
---------------------------------- |
|
Version 2.0: January 22nd, 2014 |
|
|
|
Release 2.0 deprecates verison 1.0 and brings a lot of crucial changes. |
|
|
|
[ API changes ] |
|
|
|
- API version has been bumped to 2.0 (see cs_version() API) |
|
- New API cs_strerror(errno) returns a string describing error code given |
|
in its only argument. |
|
- cs_version() now returns combined version encoding both major & minor versions. |
|
- New option CS_OPT_MODE allows to change engine’s mode at run-time with |
|
cs_option(). |
|
- New option CS_OPT_MEM allows to specify user-defined functions for dynamically |
|
memory management used internally by Capstone. This is useful to embed Capstone |
|
into special environments such as kernel or firware. |
|
- New API cs_support() can be used to check if this lib supports a particular |
|
architecture (this is necessary since we now allow to choose which architectures |
|
to compile in). |
|
- The detail option is OFF by default now. To get detail information, it should be |
|
explicitly turned ON. The details then can be accessed using cs_insn.detail |
|
pointer (to newly added structure cs_detail) |
|
|
|
|
|
[ Core changes ] |
|
|
|
- On memory usage, Capstone uses much less memory, but a lot faster now. |
|
- User now can choose which architectures to be supported by modifying config.mk |
|
before compiling/installing. |
|
|
|
|
|
[ Architectures ] |
|
|
|
- Arm |
|
- Support Big-Endian mode (besides Little-Endian mode). |
|
- Support friendly register, so instead of output sub "r12,r11,0x14", |
|
we have "sub ip,fp,0x14". |
|
- Arm64: support Big-Endian mode (besides Little-Endian mode). |
|
- PowerPC: newly added. |
|
- Mips: support friendly register, so instead of output "srl $2,$1,0x1f", |
|
we have "srl $v0,$at,0x1f". |
|
- X86: bug fixes. |
|
|
|
|
|
[ Python binding ] |
|
|
|
- Python binding is vastly improved in performance: around 3 ~ 4 times faster |
|
than in 1.0. |
|
- Cython support has been added, which can further speed up over the default |
|
pure Python binding (up to 30% in some cases) |
|
- Function cs_disasm_quick() & Cs.disasm() now use generator (rather than a list) |
|
to return succesfully disassembled instructions. This improves the performance |
|
and reduces memory usage. |
|
|
|
|
|
[ Java binding ] |
|
|
|
- Better performance & bug fixes. |
|
|
|
|
|
[ Miscellaneous ] |
|
|
|
- Fixed some installation issues with Gentoo Linux. |
|
- Capstone now can easily compile/install on all *nix, including Linux, OSX, |
|
{Net, Free, Open}BSD & Solaris. |
|
|
|
