NAME

fpuversion4 − print the Sun-4 FPU version

SYNOPSIS

/usr/etc/fpuversion4

AVAILABILITY

Sun-4 systems only. 

DESCRIPTION

fpuversion4 reads the %fsr register to determine the FPU version installed on a Sun-4.  The printed version field contains a value in the range 0-7; by SPARC convention 7 indicates that no FPU is installed, so floating-point instructions are always emulated in the kernel.
