ARCH_MAX_ALIGNMENT_INCREASE

#define ARCH_MAX_ALIGNMENT_INCREASE

Maximum extra space needed for alignment.

The ArchAlignMemorySize() can increase the required memory by no more than ARCH_MAX_ALIGNMENT_INCREASE.

ARCH_CACHE_LINE_SIZE

#define ARCH_CACHE_LINE_SIZE

The size of a CPU cache line on the current processor architecture in bytes.
