We *know* we have things like CMOV, SSE2 etc -so take advantage of it. +Set WITH_LIB32=yes in /etc/make.conf and do a buildworld/installworld. -At some point libc would be configured to use the fast syscall/sysret -instructions (instead of int 0x80) since we have a known minimum feature -set and don't have to do runtime tests for it. - -libpthread could use the amd64 sysarch syscalls for setting %fs/%gs -since we don't have USER_LDT. This would be a heck of a lot easier than -trying to run a real i386-built libc/libpthread. - -Again, this hack is a stopgap until something is integrated into world. +Alternatively, if you have just done a buildworld/installworld, you +might be able to 'make build32' and 'make install32' in the top of the +/usr/src tree. |
