+%% PREPASS FOR ITERATED REGISTER ALLOCATORS
+%%
+%% Implements a trivial partial but optimal fast register allocator to be used
+%% as the first pass of the register allocation loop.
+%%
+%% The idea is to drastically reduce the number of temporaries, so as to speed
+%% up the real register allocators.
+%%
+%% * Spills trivially unallocatable temps
+%% This relies on the fact that calls intentionally clobber all registers.
+%% Since this is the case, any temp that is alive over a call can't possibly
+%% be allocated to anything but a spill slot.
+%%
+%% * Partitions the program at points where no pseudos that were not spiled are
+%% live, and then do register allocation on these partitions independently.
+%% These program points are commonly, but not exclusively, the call
+%% instructions.
+%%
+%% TODO
+%% * This module seems very successful at finding every single spill; register
+%% allocation performance should be improved if we short-circuit the first
+%% hipe_regalloc_loop iteration, skipping directly to rewrite without ever
+%% calling RegAllocMod.
