## Detailed Description

SPARC64 Board Support Packages.

## Macro Definition Documentation

## ◆ STACK_ALIGNMENT

#define STACK_ALIGNMENT 16

According to SPARC Compliance Definition, every stack frame is 16-byte aligned.

## ◆ STACK_ARG_SAVE_AREA_SIZE

#define STACK_ARG_SAVE_AREA_SIZE (6 * STACK_ITEM_SIZE)

Six extended words for first six arguments.

## ◆ STACK_BIAS

#define STACK_BIAS 2047

By convention, the actual top of the stack is sp + STACK_BIAS.

## ◆ STACK_WINDOW_SAVE_AREA_SIZE

#define STACK_WINDOW_SAVE_AREA_SIZE (16 * STACK_ITEM_SIZE)

16-extended-word save area for i[0-7] and l[0-7] registers.
