LibTCGTranslate

A library to translate native code for multiple architectures into Tiny Code Generator (TCG) based intermediate representation (IR), based upon the QEMU translators.

Features

• Supports ARM (including Thumb and Thumb2), AArch64, x86 and x64 translators.
• C API exposed.
• C++ Wrapper.
• Thread Safe (per LibTCGTContext).
• MSVC 2017 build solution.
• Explicit condition code eflags access for the x86 and x64 translators.

Build

Open the .\build\msvc\TCGTranslate.sln solution in Visual Studio 2017 and Build the solution.

Test Usage

After you build the solution you can examine translation using the TestLibTCGTranslate application. For example, the ARM instruction str r2, [sp, #-0x4]! is encoded as 04202DE5 and can be translated as follows:

>TestLibTCGTranslate.exe /arm /buffer 04202DE5 /max_insns 1
insn_start 0x100000
        mov_i32 tmp5, sp
        movi_i32 tmp6, 0xfffffffc
        add_i32 tmp5, tmp5, tmp6
        mov_i32 tmp6, r2
        mov_i32 tmp7, tmp5
        qemu_st_i32 tmp6, tmp7, leul
        mov_i32 sp, tmp5
        goto_tb 0x1
        movi_i32 pc, 0x100004
        exit_tb 0x31a30c1
