-rtl_to_x86:
-* recognise alub(X,X,sub,1,lt,L1,L2,P) and turn it into 'dec',
- this might improve the reduction test code slightly (X is
- the pseudo for FCALLS)
-* recognise alu(Z,X,add,Y) and turn it into 'lea'.
-* rewrite tailcalls as parallel assignments before regalloc
-
-x86:
-* Use separate constructors for real regs (x86_reg) and pseudos (x86_temp).
-
-Frame:
-* drop tailcall rewrite
-
-Registers:
-* make the 2 regs now reserved for frame's tailcall rewrite available for arg passing
-
-Optimizations:
-* replace jcc cc,L1; jmp L0; L1: with jcc <not cc> L0; L1: (length:len/2)
-* Kill move X,X insns, either in frame or finalise
-* Instruction scheduling module
-* We can now choose to not have HP in %esi. However, this currently loses
- performance due to (a) repeated moves to/from P_HP(P), and (b) spills of
- the temp that contains a copy of P_HP(P). Both of these problems should be
- fixed, and then, if we don't have any noticeable performance degradation, we
- should permanently change to a non-reserved HP strategy.
