NAME

oldsun3cvt − convert large Sun-2 system executables to Sun-3 system executables

SYNOPSIS

/usr/old/sun3cvt [ oldfile [ newfile ] ]

DESCRIPTION

Note: This program is considered to be obsolete, and will not be distributed or supported in future Sun releases. 

sun3cvt converts an old Sun-2 system program file (predating Sun release 3.0) into a Sun-3 system executable file. 

The default oldfile is a.out.  The default newfile is sun3.out. 

sun3cvt attempts to create a file of the same type (magic number).  However, for sharable-text files with less than 128kb of text, the new file will not be sharable (since Sun-3 data segments must begin on 128kb boundaries).  Also, most programs have some text in the data segment as a consequence of the new larger Sun-3 system page and segment sizes. 

execve(2) executes an old Sun-2 system program file, but the program’s text is not sharable.  Old pure-text programs with text segments larger than 128kb can be made sharable on machines running release 3.0 or subsequent releases by using sun3cvt.
