+%% TEMPORARY LIVE RANGE SPLITTING PASS
+%%
+%% Live range splitting is useful to allow a register allocator to allocate a
+%% temporary to register for a part of its lifetime, even if it cannot be for
+%% the entirety. This improves register allocation quality, at the cost of
+%% making the allocation problem more time and memory intensive to solve.
+%%
+%% Optimal allocation can be achieved if all temporaries are split at every
+%% program point (between all instructions), but this makes register allocation
+%% infeasably slow in practice. Instead, this module uses heuristics to choose
+%% which temporaries should have their live ranges split, and at which points.
+%%
+%% The range splitter only considers temps which are live during a call
+%% instruction, since they're known to be spilled. The control-flow graph is
+%% partitioned at call instructions and splitting decisions are made separately
+%% for each partition. The register copy of a temp (if any) gets a separate name
+%% in each partition.
+%%
+%% There are three different ways the range splitter may choose to split a
+%% temporary in a program partition:
+%%
+%% * Mode1: Spill the temp before calls, and restore it after them
+%% * Mode2: Spill the temp after definitions, restore it after calls
+%% * Mode3: Spill the temp after definitions, restore it before uses
+%%
+%% To pick which of these should be used for each temp×partiton pair, the range
+%% splitter uses a cost function. The cost is simply the sum of the cost of all
+%% expected stack accesses, and the cost for an individual stack access is based
+%% on the probability weight of the basic block that it resides in. This biases
+%% the range splitter so that it attempts moving stack accesses from a functions
+%% hot path to the cold path.
+%%
+%% The heuristic has a couple of tuning knobs, adjusting its preference for
+%% different spilling modes, aggressiveness, and how much influence the basic
+%% block probability weights have.
+%%
+%% Edge case not handled: Call instructions directly defining a pseudo. In that
+%% case, if that pseudo has been selected for mode2 spills, no spill is inserted
+%% after the call.

+%% RESTORE REUSE LIVE RANGE SPLITTING PASS
+%%
+%% This is a simple live range splitter that tries to avoid sequences where a
+%% temporary is accessed on stack multiple times by keeping a copy of that temp
+%% around in a register.
+%%
+%% At any point where a temporary that is expected to be spilled (see uses of
+%% spills_add_list/2) is defined or used, this pass considers that temporary
+%% "available".
+%%
+%% Limitations:
+%% * If a live range part starts with several different restores, this module
+%% will introduce a new temp number for each of them, and later be forced to
+%% generate phi blocks. It would be more efficient to introduce just a
+%% single temp number. That would also remove the need for the phi blocks.
+%% * If a live range part ends in a definition, that definition should just
+%% define the base temp rather than the substitution, since some CISC
+%% targets might be able to inline the memory access in the instruction.

+%% Analysis pass
+%%
+%% The analysis pass collects the set of temps we're interested in splitting
+%% (Spills), and computes three dataflow analyses for this subset of temps.
+%%
+%% Avail, which is the set of temps which are available in register from a
+%% previous (potential) spill or restore without going through a HasCall
+%% block.
+%% Want, which is a liveness analysis for the subset of temps used by an
+%% instruction that are also in Avail at that point. In other words, Want is
+%% the set of temps that are split (has a register copy) at a particular
+%% point.
+%% Def, which are the temps that are already going to be spilled later, and so
+%% need not be spilled when they're defined.
+%%
+%% Lastly, it computes the set Self for each block, which is the temps that have
+%% avail-want pairs in the same block, and so should be split in that block even
+%% if they're not in WantIn for the block.
