max_function_inst[:n] 允许函数因自动内联而最多增加 n 个伪指令(在编译器的内部表示中计数)。 max_growth[:n] 允许自动内联程序将程序大小最多增大 n%,其中大小以伪指令数度量。 min_counter[:n] 为了考虑要自动内联的函数而通过分析反馈 (-xprofile) 度量的最小调用点频率计数。 仅当使用分析反馈 (-xpr...
在所有 Solaris 平台和不支持 64 位的 Linux 平台上,ILP32 内存模型(32 位 int、long、pointer 数据类型)是缺省值。在启用了 64 位的 Linux 平台上缺省为 LP64 内存模型(64 位 long 和指针数据类型)。-m64 仅允许在支持 LP64 模型的平台上使用。

A thread is created and starts using the function pthread_create(). It takes fourparameters: Name Type Description --- ID pthread_t * Reference (or pointer) to the ID of the thread. Attributes pthread_attr_t * Used to set the attributes of a thread(e.g.,...
Objective-C在C语言的基础上添加了面向对象特性。使用“消息结构”(message structure)而非“函数调用”(function calling)。OC由Smalltalk演化而来,后者是消息型语言的鼻祖。 消息与函数调用的关键区别在于:使用消息结构的语言,其运行时所应执行的代码有运行环境来决定;而使用函数调用的语言,则有编译器决定。
Pointer instances are created by calling the pointer() function on a ctypes type: from ctypes import * i = c_int(42) pi = pointer(i) Pointer instances have a contents attribute which returns the object to which the pointer points, the i object above: ...
