ChangeLog 4.0 alpha1

(Look here for the detailed changelog of v3.0.3)

This page details all the changes in the version 4.0-alpha1. While far from the final version 4.0, this is stable enough for some architectures such as X86 and ARM.

NOTE: changes are listed in time order: newer changes are at the top, older changes are at the bottom.

Library:

• New option CS_OPT_MNEMONIC to customize instruction mnemonics (see docs).
• New API cs_regs_access() & access info for instruction operands (see documentation).
• make.sh has been rewritten to be faster & more portable.
• pkg-config is consistent with installation.

X86:

• Properly decode some instructions beginning with f3 or 660f, where f3 & 66 are not prefix.
• Correct the size of immediate operand for instruction CMP8i8.
• Update core with 46 instructions added (including latest extensions from Broadwell CPU).
• Fix operand size of instructions with operand PTR []
• Add prefix constant REPE (= REP).
• Handle the opcode 0x82 (non-64bit instructions).
• Properly handle instructions using CR9~CR15 registers.
• Remove dead SSE_CC constants.
• Add new registers DR8-DR15.
• New undocumented instructions FDISI8087_NOP, FENI8087_NOP & FFREEP.

PowerPC:

• Update core with 164 instructions added (with new QPX extension).

Mips:

• Update core with 40 instructions added.
• Sanity check for the input size for MIPS64 mode.

Arm:

• BLX instruction modifies PC & LR registers.
• Remove bogus instructions ASRS, LSRS, SUBS and MOVS.
• Update core with 2 instructions added.
• Add lshift field to arm_op_mem.

Python:

• X86Op.avx_zero_mask now has c_bool type, not c_uint8 type.

Make sure to compile and install new code:

    $ ./make.sh
    $ sudo ./make.sh install

Just in case, always remember to reinstall bindings whenever you update the core to maintain the compatibility between the core & the bindings. For example, with Python binding, do:

    $ cd bindings/python
    $ sudo make install
