Change Details

Currently we have a very nasty ABI breakage, because we will pass arguments in XMM registers, however the callee is expecting them on stack. Not that it is perfectly fine to spill XMM registers on stack even for functions with noimplicitfloat attribute: the spill is guarded by additional check and only happens if some XMM registers are live-ins with arguments.
