linux - 配置中的 Endian 属性。文件

Question

我想通过 simplescalar 运行基准测试，但是当我想通过此命令运行它时:

./sim-profile anagram.pisa-big words < anagram.in > OUT

它给了我以下内容:

fatal: PISA binary `anagram.pisa-big'  has wrong endian format

有人告诉我，我必须执行以下操作:

1. 运行./sim-profile -confugdump config_new.cfg
2. 然后写入./sim-profile -confugdump config_new.cfg
3. 更改属性并将 endian 属性更改为 big-endian

但问题是我找不到执行此操作的属性。打开此文件后，我有以下内容:

他们的FAQ另有建议。它说:

Q5: Whenever I try to run binaries, I always get the error: "binary endian does not match host endian", what is wrong?

Your binaries are the wrong endian! Either you mis-configured GCC, GAS or GLD, or you grabbed the wrong binary release. Reconfigure the compilers to the opposite endian, or get the other binary release. To determine the endian of your host machine, run "sysprobe -s", located in the SimpleScalar simulator directory.

文件扩展名pisa-big表明您采用big-endian格式。尝试将其放入 pisa-little (或任何名称)中。
