+// These functions deal with getting and setting a JavaScript Typed Array's data.
+// The process in which this is done is extremely backwards, prohibitively
+// memory inefficient and painfully slow.
+
+// JavaScriptCore still doesn't have an API to deal with Typed Arrays directly
+// and nobody seems to care. See this WebKit bug for the details:
+// https://bugs.webkit.org/show_bug.cgi?id=120112
+
+// The naive method of getting the array's data would be to read the "length"
+// property and call JSObjectGetPropertyAtIndex() for each element. This function
+// returns a JSValue and since the array's data is just a raw memory pointer
+// internally, this JSValue has be constructed first by JSC. Afterwards this
+// JSValue has to be converted back into an int and stored in a native buffer.
+// This ordeal takes about 1200ms per megabyte on an iPhone5S.
+
+// So, instead of extracting each byte on its own, we create Int32 view on the
+// Array, so that we can extract 4 bytes at a time. Now, the fastest method to
+// get to the values is to call a function with .apply(null, theInt32Array).
+// This causes the typed array to be converted into plain JSValues - we can then
+// iterate all function arguments and convert each JSValue into a Int32.
+
+// There's one big caveat, though: a function can only be called with 64k
+// arguments at once, or it will blow the stack. So we have to divide the Int32
+// Array into smaller subarrays and convert the data in chunks.
+
+// Setting the Array's data works about the same. We can create a plain JS
+// Array in reasonable time by treating the data as 32bit ints. This plain
+// Array can then be used to call .set() on an Int32 View of the Typed Array.
+
+// To be able to quickly determine the type of a typed array, we install an
+// enum with the type id ("__ejTypedArrayType") onto each array constructor's
+// prototype.
+
+// This all brings the time down to about 7ms per megabyte for reading and about
+// 20ms per megabyte for writing. Even though this 7ms/MB number may not sound
+// all too bad, keep in mind that it's still 7ms slower than what we would have
+// with a better API.

+ * Explanation of H array and index values:
+ *
+ * The context's H array is actually the concatenation of two arrays
+ * defined by SHA1, the H array of state variables (5 elements),
+ * and the W array of intermediate values, of which there are 16 elements.
+ * The W array starts at H[5], that is W[0] is H[5].
+ * Although these values are defined as 32-bit values, we use 64-bit
+ * variables to hold them because the AMD64 stores 64 bit values in
+ * memory MUCH faster than it stores any smaller values.
+ *
+ * Rather than passing the context structure to shaCompress, we pass
+ * this combined array of H and W values.  We do not pass the address
+ * of the first element of this array, but rather pass the address of an
+ * element in the middle of the array, element X.  Presently X[0] is H[11].
+ * So we pass the address of H[11] as the address of array X to shaCompress.
+ * Then shaCompress accesses the members of the array using positive AND
+ * negative indexes.
+ *
+ * Pictorially: (each element is 8 bytes)
+ * H | H0 H1 H2 H3 H4 W0 W1 W2 W3 W4 W5 W6 W7 W8 W9 Wa Wb Wc Wd We Wf |
+ * X |-11-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 X0 X1 X2 X3 X4 X5 X6 X7 X8 X9 |
+ *
+ * The byte offset from X[0] to any member of H and W is always
+ * representable in a signed 8-bit value, which will be encoded
+ * as a single byte offset in the X86-64 instruction set.
+ * If we didn't pass the address of H[11], and instead passed the
+ * address of H[0], the offsets to elements H[16] and above would be
+ * greater than 127, not representable in a signed 8-bit value, and the
+ * x86-64 instruction set would encode every such offset as a 32-bit
+ * signed number in each instruction that accessed element H[16] or
+ * higher.  This results in much bigger and slower code.

+ *
+ * The functions that compute the new values of the 5 state variables
+ * A-E are done in 4 groups of 20 operations (or you may also think
+ * of them as being done in 16 groups of 5 operations).  They are
+ * done by the SHA_RNDx macros below, in the right column.
+ *
+ * The functions that set the 16 values of the W array are done in
+ * 5 groups of 16 operations.  The first group is done by the
+ * LOAD macros below, the latter 4 groups are done by SHA_MIX below,
+ * in the left column.
+ *
+ * gcc's optimizer observes that each member of the W array is assigned
+ * a value 5 times in this code.  It reduces the number of store
+ * operations done to the W array in the context (that is, in the X array)
+ * by creating a W array on the stack, and storing the W values there for
+ * the first 4 groups of operations on W, and storing the values in the
+ * context's W array only in the fifth group.  This is undesirable.
+ * It is MUCH bigger code than simply using the context's W array, because
+ * all the offsets to the W array in the stack are 32-bit signed offsets,
+ * and it is no faster than storing the values in the context's W array.
+ *
+ * The original code for sha_fast.c prevented this creation of a separate
+ * W array in the stack by creating a W array of 80 members, each of
+ * whose elements is assigned only once. It also separated the computations
+ * of the W array values and the computations of the values for the 5
+ * state variables into two separate passes, W's, then A-E's so that the
+ * second pass could be done all in registers (except for accessing the W
+ * array) on machines with fewer registers.  The method is suboptimal
+ * for machines with enough registers to do it all in one pass, and it
+ * necessitates using many instructions with 32-bit offsets.
+ *
+ * This code eliminates the separate W array on the stack by a completely
+ * different means: by declaring the X array volatile.  This prevents
+ * the optimizer from trying to reduce the use of the X array by the
+ * creation of a MORE expensive W array on the stack. The result is
+ * that all instructions use signed 8-bit offsets and not 32-bit offsets.
+ *
+ * The combination of this code and the -O3 optimizer flag on GCC 3.4.3
+ * results in code that is 3 times faster than the previous NSS sha_fast
+ * code on AMD64.
