bochs神奇的任意斷點調試

#=======================================================================

# MAGIC_BREAK:

# This enables the "magic breakpoint" feature when using the debugger.

# The useless cpu instruction XCHG BX, BX causes Bochs to enter the

# debugger mode. This might be useful for software development.

#

# Example:

#   magic_break: enabled=1

#======================================================================

正如這個配置名字所描述的那樣magic，真正做到任意斷點調試！

如果是GCC的嵌入彙編可以這樣寫：

__asm__("xchg %%bx,%%bx"::);
