NAME

       isalist - display the native instruction sets executable on this platform

SYNOPSIS

       isalist

DESCRIPTION

       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(2).

       The names are space-separated and are ordered in the sense of best performance. That is, earlier-named instruction sets	may  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(5).  These names may or may not match predefined names or compiler
       options in the C language compilation system,
