NAME
fpversion - print information about the system CPU and FPU
SYNOPSIS
fpversion [ -foption ]
DESCRIPTION
fpversion prints information about the system CPU and all
available floating-point hardware on the standard output.
(It replaces the older foption and fpaversion.)
Invoked without an argument, some of the following informa-
tion will be displayed: CPU type and approximate clock
rate, FPU type, apparent mask number and approximate clock
rate, and highest performance floating-point code generation
option. The type of information displayed depends upon the
system and the floating-point hardware available. The clock
rate is derived by executing instructions in a loop and tim-
ing with getrusage(2) and is thus somewhat variable.
Invoked with -foption as its argument, it prints only the
fastest floating-point code generation option for that par-
ticular system. This usage is intended for shell scripts
and Makefiles that compile programs with the fastest
floating-point code generation option according to the
floating-point hardware present.
OPTIONS
-foption Prints the fastest floating-point code genera-
tion option according to the floating-point
hardware present.
