[fpc-devel] Recent changes to x86-64 peephole optimisation

[J. Gareth Moreton]

Hi everyone,

I've been away for a few days so I haven't 
been paying too much attention to the trunk, 
but I've noticed some new changes to the x86-
64 peephole optimized that look interesting. 
Can someone fill me in on what they're meant 
to do and the motivation behind the 
additions? This is just so I fully understand 
what everything is doing and don't 
accidentally overwrite something.
