/*
 * Loading 32-bit constants on a sparc is expensive since it involves both
 * a `sethi' and an `or'.  thus, we instead use `ld' to load the constants
 * from an array called `sha2_consts'.  however, on intel (and perhaps other
 * processors), it is cheaper to load the constant directly.  thus, the c
 * code in SHA transform functions uses the macro SHA2_CONST() which either
 * expands to a constant or an array reference, depending on
 * the architecture the code is being compiled for.
 *
 * SHA512 constants are used for SHA384
