-# There is a way to use XMM registers (which always exist for x86-64!) for W[]
-# For example, if we load W as follows:
-# %xmm0: w[0x0] w[0x1] w[0x2] w[0x3]
-# %xmm4: w[0x4] w[0x5] w[0x6] w[0x7]
-# %xmm8: w[0x8] w[0x9] w[0xa] w[0xb]
-# %xmm12: w[0xc] w[0xd] w[0xe] w[0xf]
-# then the xor'ing operation to generate next W[0..3] is:
-# movaps %xmm0, %xmmT2
-# palignr $0x8, %xmm4, %xmmT2 # form (w[0x2],w[0x3],w[0x4],w[0x5])
-# # Right-shifts xmm4:xmmT2 by 8 bytes. Writes shifted result to xmmT2. SSSE3 insn.
-# movaps %xmm0, %xmmT13
-# palignr $0x4,%xmm0,%xmmT13 # form (w[0xd],w[0xe],w[0xf],w[0x0])
-# xmm0 = xmm0 ^ t2 ^ xmm8 ^ t13
-# xmm0 = rol32(xmm0,1) # no such insn, have to use pslld+psrld+or
-# and then results can be extracted for use:
-# movd %xmm0, %esi # new W[0]
-# pextrd $1, %xmm0, %esi # new W[1]
-# # SSE4.1 insn. Can use EXTRACTPS (also SSE4.1)
-# pextrd $2, %xmm0, %esi # new W[2]
-# pextrd $3, %xmm0, %esi # new W[3]
-# ... but this requires SSE4.1 and SSSE3, which are not universally available on x86-64.
+# Based on http://arctic.org/~dean/crypto/sha1.html.
+# ("This SHA1 implementation is public domain.")
+#
+# x86-64 has at least SSE2 vector insns always available.
+# We can use them without any CPUID checks (and without a need
+# for a fallback code if needed insns are not available).
+# This code uses them to calculate W[] ahead of time.
+#
+# Unfortunately, results are passed from vector unit to
+# integer ALUs on the stack. MOVD/Q insns to move them directly
+# from vector to integer registers are slower than store-to-load
+# forwarding in LSU (on Skylake at least).
+#
+# The win against a purely integer code is small on Skylake,
+# only about 7-8%. We offload about 1/3 of our operations to the vector unit.
+# It can do 4 ops at once in one 128-bit register,
+# but we have to use x2 of them because of W[0] complication,
+# SSE2 has no "rotate each word by N bits" insns,
+# moving data to/from vector unit is clunky, and Skylake
+# has four integer ALUs unified with three vector ALUs,
+# which makes pure integer code rather fast, and makes
+# vector ops compete with integer ones.
+#
+# Zen3, with its separate vector ALUs, wins more, about 12%.
