isalist 描述
isalist在sysinfo的SI_ISALIST命令返回的标准输出上打印在该平台上可执行的本机指令集的名称。
名称以空格分隔,并按最佳性能排序。也就是说,较早命名的指令集可能包含更多的指令。为较早命名的指令集编译的程序在本机上的运行极有可能比为较早命名的指令集编译的相同程序运行得更快。
为没有出现在列表中的指令集编译的程序很可能会遇到性能下降或根本无法在该计算机上运行的情况。
isalist中列出了系统已知的指令集名称。这些名称可能匹配或可能不匹配C语言编译系统中的预定义名称或编译器选项。
isalist prints the names of the native instruction sets executable on this platform on the standard output, as returned by the SI_ISALIST command of sysinfo.
The names are space-separated and are ordered in the sense of best performance. That is, earlier-named instruction sets might contain more instructions than later-named instruction sets; a program that is compiled for an earlier-named instruction sets will most likely run faster on this machine than the same program compiled for a later-named instruction set.
Programs compiled for instruction sets that do not appear in the list will most likely experience performance degradation or not run at all on this machine.
The instruction set names known to the system are listed in isalist. These names might or might not match predefined names or compiler options in the C language compilation system.
