FPUVERSION4(8) — MAINTENANCE COMMANDS
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.
