最近看了傅琳琳的那篇OAL的点点滴滴(http://www.vckbase.com/document/viewdoc/?id=1379)，他告诉我StartUp（）函数是CE启动的第一个函数，可是我硬是没有搜索到那个什么鬼函数在哪里，在MSDN帮助文档里面也说：
This function is the first function to be called when the OS is booted from either the boot loader or reset vector.
void StartUp(void);
ParametersNone.
Return ValuesNone.
RemarksThis function is the first function called during boot up. The function needs to initialize the CPU to a known state and then call one of the kernel initialization functions, either KernelInitialize or KernelStart.
可是我为什么找不到呢？
嘿嘿，在一阵子搜索之后，我放弃了，然后开始翻启动代码那段汇编语言，看到一个词语不认识：LEAF_ENTRY ，查看MSDN的帮助文档说，
This macro declares the beginning of a routine that does not require any prolog code.
LEAF_ENTRY Name[,
[Section=]SectionName]
ParametersName Name is the routine name and is in the global name space. SectionName SectionName is the name of the section in which the entry will appear; it is optional and defaults to .text. Return ValuesNone.
RemarksA LEAF_ENTRY must have an associated ENTRY_END.
Each supported microprocessor contains a definition for this macro in a microprocessor-specific header file. The following table shows the supported microprocessor families and the related header file that contains the macro definition for that family.

Kxarm.h
SH3, SH4

嘿嘿，原来就是它定义了StartUp啊，但是有些地方仍然没有想通，比如这个例程调用了很多C的函数，但这个时候好像还没有初始化栈堆，哪位知道原因，烦请告诉我一声。
