ArmIE的安装

参考：https://developer.arm.com/tools-and-software/server-and-hpc/arm-architecture-tools/arm-instruction-emulator/installing-arm-instruction-emulator

运行环境：Qemu+arm64版本的ubuntu16.04

　　前面一篇博客使用Qemu运行Ubuntu文件系统 —— 搭建SVE学习环境（2）中才Qemu上运行了一个ubuntu16.04的系统，然后再在其中安装了ArmIE，来模拟SVE指令的执行。下面简单介绍一下ArmIE的安装方法，关于ArmIE的详细介绍，请参考ARM官网：Arm Instruction Emulator

第一步，安装module软件包（链接）

sudo apt-get install environment-modules

第二步、下载ArmIE安装包（链接）

　　可以到这里下载ArmIE安装包，这里下载ARM-Instruction-Emulator_19.2_AArch64_Ubuntu_16.04_aarch64.tar.gz

　　

第三步、解压安装ArmIE

tar -xvf  ARM-Instruction-Emulator_19.2_AArch64_Ubuntu_16.04_aarch64.tar.gz 

cd ARM-Instruction-Emulator_19.2_AArch64_Ubuntu_16.04_aarch64

sudo ./arm-instruction-emulator-.2_Generic-AArch64_Ubuntu-.04_aarch64-linux-deb.sh

　　默认会安装到/opt/arm下，也可以通过参数-i换成别的安装路径

第四步、设置环境变量MODULEPATH

export MODULEPATH=$MODULEPATH:/opt/arm/modulefiles/

第五步、重新登录系统，使用module查看哪些模块，并加载ArmIE模块

pengdl@firefly:~$ module avail

-------------------------------------------------------------- /opt/arm/modulefiles --------------------------------------------------------------
Generic-AArch64/Ubuntu/16.04/arm-instruction-emulator/19.2 Generic-AArch64/Ubuntu/16.04/gcc_runtimes/8.2.

---------------------------------------------------------- /usr/share/modules/versions -----------------------------------------------------------
3.2.

--------------------------------------------------------- /usr/share/modules/modulefiles ---------------------------------------------------------
dot         module-git  module-info modules     null        use.own

------------------------------------------------------------- /opt/arm/modulefiles/ --------------------------------------------------------------
Generic-AArch64/Ubuntu/16.04/arm-instruction-emulator/19.2 Generic-AArch64/Ubuntu/16.04/gcc_runtimes/8.2.0

pengdl@firefly:~$ module load Generic-AArch64/Ubuntu/16.04/arm-instruction-emulator/19.2


pengdl@firefly:~$ echo $PATH
/opt/arm/arm-instruction-emulator-19.2_Generic-AArch64_Ubuntu-16.04_aarch64-linux/bin64:/home/pengdl/bin:/home/pengdl/.local/bin:/home/pengdl/sve_acle_cross/bin:/opt/gstreamer/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
pengdl@firefly:~$

为了实现以后每次开机都可以直接使用ArmIE，可以将 module load Generic-AArch64/Ubuntu/16.04/arm-instruction-emulator/19.2 加到.bashrc中。

第六步、测试

pengdl@firefly:~$ armie
Execute binaries containing SVE instructions on Armv8-A hardware

Usage:
  armie [emulation parameters] -- <command to execute>

Examples:
  armie -msve-vector-bits= -- ./sve_program
  armie -msve-vector-bits= --iclient libinscount.so -- ./sve_program --opt foo
  armie -e libmemtrace_sve_512.so -i libmemtrace_simple.so -- ./sve_program

Flags:
  -m<string>                    Architecture specific options. Supported options:
    -msve-vector-bits=<uint>    Vector length to use. Must be a multiple of  bits up to  bits
    -mlist-vector-lengths       List all valid vector lengths
  -e, --eclient <client>        An emulation client based on the DynamoRIO API
                                If this is not specified, the default SVE client is used
  -i, --iclient <client>        An instrumentation client based on the DynamoRIO API
  -x, --unsafe-ldstex           Enables a workaround which avoids an exclusive load/store bug on certain AArch64 hardware
                                (See 'Known Issues' in RELEASE_NOTES.txt for details)
  -s, --show-drrun-cmd          Writes the full DynamoRIO drrun command used to execute ArmIE to stderr
                                This can be useful when debugging or developing clients
  -h, --help                    Prints this help message
  -V, --version                 Prints the version

完。
