Linux ld-m--verbose实际上做什么？

我被这个命令弄糊涂了。手册页说它“模拟仿真链接器。您可以使用--verbose或-V选项列出可用的仿真。”但是“可用仿真”是什么意思

例如，我使用以下命令链接对象：

ld -r -nostdlib -L/media/wind/lab/xen/xen/xen-4.4.0/stubdom/cross-root-x86_64/x86_64-xen-elf/lib  \

使用内部链接器脚本：
==================================================
（>>>此处显示的脚本，忽略了此处为libc列出的大量*.o。a为什么此处没有列出*.o文件？在链接.o文件以创建硬件平台的可执行文件时，使用ld-m选项，该硬件平台作为-m选项的参数提供

例如，如果指定ld-m elf_x86_64…，则会创建一个可执行文件（假设未发生错误）可以在x86_64系统上运行的。这通常在交叉编译期间使用。例如，当您试图为与正在构建的平台不同的平台创建可执行文件时。
是不是glib已经构建，您正在链接它，而不是构建它，所以它不会显示任何对象文件？这个问题称为currently-worded非常混乱，简单地运行
ld-m--verbose
会在我的系统（Linux）上出现使用错误。
