SSE causes CPU exception 13 under virtualbox about includeos HOT 6 CLOSED

That is a general protection fault, which means it wasn't enabled (or supported).
Could be fixed by trying -msse2 or maybe my assembly to enable it is wrong

The original assembly is commented out above it, and all the enabling code is in kernel_start.cpp
Although it works here

NOTE: gcc will auto-generate SSE code as long as -msse3 is enabled
so even if the SSE testcase (in service.cpp) is disabled, you may still get a general protection fault

After a complete clean and rebuild it works fine under qemu, but there's now an exception 13 (general protection) under virtualbox. I'll label this as virtualbox-specific.

[ PASS ] Qemu inside VirtualBox
[ FAIL ] VirtualBox on MacBook Air
[ TBD ] Qemu on Trident (Production grade server)

This is not the case anymore - it runs fine on virtualboox - also on Mac.

Must have been the stack realignment issue
