如何在GDB中打印类型属性?

对:

(gdb)p

一些属性可以识别,而其他属性则无法识别。(在下面列出的内容中,find是一个布尔变量。)

gdb) p integer'size
Attempt to use a type name as an expression
(gdb) p found'size
$2 = 8
(gdb) p integer'first
$3 = -2147483648
(gdb) p integer'last
$4 = 2147483647

这是我们网站上的列表 Ada section

Only a subset of the attributes are supported:
 
     * 'First, 'Last, and 'Length on array objects (not on types and subtypes).
     * 'Min and 'Max.
     * 'Pos and 'Val.
     * 'Tag.
     * 'Range on array objects (not subtypes), but only as the right operand of the membership (in) operator.
     * 'Access, 'Unchecked_Access, and 'Unrestricted_Access (a GNAT extension).
     * 'Address.

(嗯,这个列表可能是有日期的,因为我可以做Integer'Last,尽管第一个项目符号说它对类型无效。)
