I'm trying to understand the reasoning behind decision of designers of System-V x86-64 ABI to have no callee-save vector (or floating-point) registers.
So far, I have no idea. With total of 16 XMM registers defining at least 4, but more likely 6 to 8 registers as callee-save sounds to me as obviously sane thing to do.
What am i missing?
