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 information 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 timing 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 particular 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 generation option according to the floating-point hardware present.
