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.
