Detailed Description

• 8-byte (64-bit) alignment routines.

This file provides tools for aligning boundaries of arrays, particularly of 64-bit units, e.g. double- precision floating points, to physical addresses divisible by 8, including aligning dynamically allocated memory block and aligning call stack. Currently stack alignment is disabled due to lack of compiler support for Intel assembly.
