gdb：将char数组显示为大端字节短裤

Question

假设我有一个像

char foo[] = { 0, 1, 1, 0 };

在gdbx86机器上，如果我说

p (short[2])*foo

我懂了

{256, 1}

这就是说，两个字节short按小端顺序解释。

是否有一种方便的方法（例如宏）来使gdb字节数组显示为大端短（或其他类型）呢？

Answer 1

使用set endian big。用于set endian auto切换回自动字节序选择。

(gdb) p (short[2])*foo
$1 = {256, 1}
(gdb) set endian big
The target is assumed to be big endian
(gdb) p (short[2])*foo
$2 = {1, 256}
(gdb) set endian auto
The target endianness is set automatically (currently little endian)
(gdb) p (short[2])*foo
$3 = {256, 1}
(gdb)
