英文:
any way to add parameters to gdb aliases or create a function?
问题
在gdb中，我想创建一个命令，用于打印出一个矢量寄存器：
print $ymm0.v8_int32
理想情况下，能够传入寄存器的名称，如：
pv ymm0
有没有办法做到这一点？
英文:
In gdb, I want to create a command that will print out a vector register:
print $ymm0.v8_int32
ideally, being able to pass in the name of the register, like:
pv ymm0
Is there any way to do this?

得分: 1
这大概已经足够接近了：```c(gdb) p $ymm0.v8_int32$1 = {199136, 0, 5664, 0, 0, 0, 0, 0}(gdb) define pv输入定义“pv”的命令。以一行只写“end”结束。>打印 $arg0.v8_int32>end(gdb) pv $ymm0$2 = {199136, 0, 5664, 0, 0, 0, 0, 0}
你可以将这段代码放入 ~/.gdbinit 文件中：
define pvprint $arg0.v8_int32end
也可以参考GDB文档中有关用户自定义命令的部分。
<details><summary>英文:</summary>This is probably close enough:
(gdb) p $ymm0.v8_int32
$1 = {199136, 0, 5664, 0, 0, 0, 0, 0}
(gdb) define pv
Type commands for definition of "pv".
End with a line saying just "end".
>print $arg0.v8_int32
>end
(gdb) pv $ymm0
$2 = {199136, 0, 5664, 0, 0, 0, 0, 0}
You can put this into `~/.gdbinit` as:
define pv
print $arg0.v8_int32
end
