Well, we are talking about "ibcs2 and svr4 compatibility code", which at least in theory allows you to take an IBCS2 or SVR4 binary for Intel and run it on FreeBSD. > >>They will be eliminated from -current in the coming week, unless very > >>compelling reasons to the contrary are put on the table. > > > > - Latest Java SDKs for Solaris/x86 > > - Forte C/C++ optimising compilers for Solaris/x86 (which may some day > > be used to compile FreeBSD kernel) > > If solaris has support of building the stuff used in FreeBSD then it's > not required for FreeBSD having ibsc2 and svr4 onboard. You can use Sun's compilers for Intel to generate x86 assembly code and (with a little bit of tweaking) assemble it with gas to create a native FreeBSD binary. Last time I did that (ca. 2000), I measured a 20-30% improvement in run-time execution speed. > > - Sun ONE servers for Solaris/x86 (e.g. iPlanet LDAP) > > - Oracle for Solaris/x86 > > - Numerous third-party applications for SCO and Solaris/x86 > > (e.g. backup solutions) > > Still, i fail to see the relation to FreeBSD. Sorry if i misunderstood Alex. It's relevant in so far as SVR4 emulation is concerned. Alex
