> What's the difference between cooked and non-cooked function? As far as I noticed, i386 target doesn't use cooked functions at all...

Mumble something about long overdue documentation :-(

Cooked ~= user visible / ABI
Raw ~= underlying h/w / physical / ISA registers.

> How do I store/read for example a long double, that is passed in two X87 registers? With regbuf it's stored in a place for FP0 and FP0+8 in registers array. Will it come to a single slot of a regcache now?

Er, I thought the x87 FP registers were 12 bytes?  Anyway, if the value 
really is split across two FP registers then use two separate regcache 
writes.
