Detailed Description

Low-level platform-dependent bit rotate functions.

Rotate functions conventions:

• ROL = rotate left
• ROR = rotate right
• ROLc/RORc = rotate with constant value for index (optimized when asm). Note that, in debug mode, ROLc/RORc revert to ROL/ROR since the routines are not inlined and, thus, constant constraint cannot be checked.
