-// What's wrong with compiler generated code? Because of the nature of
-// C language, compiler doesn't [dare to] reorder load and stores. But
-// being memory-bound, RC4 should benefit from reorder [on in-order-
-// execution core such as IA-64]. But what can we reorder? At the very
-// least we can safely reorder references to key schedule in respect
-// to input and output streams. Secondly, from the first [close] glance
-// it appeared that it's possible to pull up some references to
-// elements of the key schedule itself. Original rationale ["prior
-// loads are not safe only for "degenerated" key schedule, when some
-// elements equal to the same value"] was kind of sloppy. I should have
-// formulated as it really was: if we assume that pulling up reference
-// to key[x+1] is not safe, then it would mean that key schedule would
-// "degenerate," which is never the case. The problem is that this
-// holds true in respect to references to key[x], but not to key[y].
-// Legitimate "collisions" do occur within every 256^2 bytes window.
-// Fortunately there're enough free instruction slots to keep prior
-// reference to key[x+1], detect "collision" and compensate for it.
-// All this without sacrificing a single clock cycle:-) Throughput is
-// ~210MBps on 900MHz CPU, which is is >3x faster than gcc generated
-// code and +30% - if compared to HP-UX C. Unrolling loop below should
-// give >30% on top of that...

+# This is a little helper program which generates a software-pipelined
+# for RC4 encryption. The basic algorithm looks like this:
+#
+# for (counter = 0; counter < len; ++counter)
+# {
+# in = inp[counter];
+# SI = S[I];
+# J = (SI + J) & 0xff;
+# SJ = S[J];
+# T = (SI + SJ) & 0xff;
+# S[I] = SJ, S[J] = SI;
+# ST = S[T];
+# outp[counter] = in ^ ST;
+# I = (I + 1) & 0xff;
+# }
+#
+# Pipelining this loop isn't easy, because the stores to the S[] array
+# need to be observed in the right order. The loop generated by the
+# code below has the following pipeline diagram:
+#
+# cycle
+# | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |10 |11 |12 |13 |14 |15 |16 |17 |
+# iter
+# 1: xxx LDI xxx xxx xxx LDJ xxx SWP xxx LDT xxx xxx
+# 2: xxx LDI xxx xxx xxx LDJ xxx SWP xxx LDT xxx xxx
+# 3: xxx LDI xxx xxx xxx LDJ xxx SWP xxx LDT xxx xxx
+#
+# where:
+# LDI = load of S[I]
+# LDJ = load of S[J]
+# SWP = swap of S[I] and S[J]
+# LDT = load of S[T]
+#
+# Note that in the above diagram, the major trouble-spot is that LDI
+# of the 2nd iteration is performed BEFORE the SWP of the first
+# iteration. Fortunately, this is easy to detect (I of the 1st
+# iteration will be equal to J of the 2nd iteration) and when this
+# happens, we simply forward the proper value from the 1st iteration
+# to the 2nd one. The proper value in this case is simply the value
+# of S[I] from the first iteration (thanks to the fact that SWP
+# simply swaps the contents of S[I] and S[J]).
+#
+# Another potential trouble-spot is in cycle 7, where SWP of the 1st
+# iteration issues at the same time as the LDI of the 3rd iteration.
+# However, thanks to IA-64 execution semantics, this can be taken
+# care of simply by placing LDI later in the instruction-group than
+# SWP. IA-64 CPUs will automatically forward the value if they
+# detect that the SWP and LDI are accessing the same memory-location.
+
+# The core-loop that can be pipelined then looks like this (annotated
+# with McKinley/Madison issue port & latency numbers, assuming L1
+# cache hits for the most part):
+
+# operation: instruction: issue-ports: latency

+
+# There are several points worth making here:
+
+# - Note that due to the bypass/forwarding-path, the first two
+# phases of the loop are strangly mingled together. In
+# particular, note that the first stage of the pipeline is
+# using the value of "J", as calculated by the second stage.
+# - Each bundle-pair will have exactly 6 instructions.
+# - Pipelined, the loop can execute in 3 cycles/iteration and
+# 4 stages. However, McKinley/Madison can issue "st1" to
+# the same bank at a rate of at most one per 4 cycles. Thus,
+# instead of storing each byte, we accumulate them in a word
+# and then write them back at once with a single "st8" (this
+# implies that the setup code needs to ensure that the output
+# buffer is properly aligned, if need be, by encoding the
+# first few bytes separately).
+# - There is no space for a "br.ctop" instruction. For this
+# reason we can't use module-loop support in IA-64 and have
+# to do a traditional, purely software-pipelined loop.
+# - We can't replace any of the remaining "add/zxt1" pairs with
+# "padd1" because the latency for that instruction is too high
+# and would push the loop to the point where more bypasses
+# would be needed, which we don't have space for.
+# - The above loop runs at around 3.26 cycles/byte, or roughly
+# 440 MByte/sec on a 1.5GHz Madison. This is well below the
+# system bus bandwidth and hence with judicious use of
+# "lfetch" this loop can run at (almost) peak speed even when
+# the input and output data reside in memory. The
+# max. latency that can be tolerated is (PREFETCH_DISTANCE *
+# L2_LINE_SIZE * 3 cyc), or about 384 cycles assuming (at
+# least) 1-ahead prefetching of 128 byte cache-lines. Note
+# that we do NOT prefetch into L1, since that would only
+# interfere with the S[] table values stored there. This is
+# acceptable because there is a 10 cycle latency between
+# load and first use of the input data.
+# - We use a branch to out-of-line bypass-code of cycle-pressure:
+# we calculate the next J, check for the need to activate the
+# bypass path, and activate the bypass path ALL IN THE SAME
+# CYCLE. If we didn't have these constraints, we could do
+# the bypass with a simple conditional move instruction.
+# Fortunately, the bypass paths get activated relatively
+# infrequently, so the extra branches don't cost all that much
+# (about 0.04 cycles/byte, measured on a 16396 byte file with
+# random input data).
