* 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
