Can anyone give me a pointer to help me with x86 register allocation?
That wonderful Intel processor family has such register-specific instructions
(e.g. MUL result always goes into DX:AX) that I fear it will be difficult
to write an easy register allocation algorithm.
[On the 8086 to 286 it's a stinker since all the registers are different.
The 386 and later members of the family make the job somewhat easier due
to more complete register addressing modes. I don't know of any theory that
will help much, the graph coloring stuff is all intended for architectures
with more registers. -John]
