# $FreeBSD$ This script is a stopgap for building tuned 32 bit (but i386 ABI compatable) libraries for amd64 systems. We *know* we have things like CMOV, SSE2 etc so take advantage of it. 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.
