.const 初始化的全局const变量和static const变量和字符串常量 不超过64K长度 .econst 长调用的常量 数据中的任何地方 .pinit 全局对象的构造函数表 代码 .switch switch语句产生的表 代码或者数据 .text 可执行代码和常数 代码 没初始化的段是由未初始化的变量，堆栈和malloc产生的内存。下表列出了由编译器产生的没初始化段。 没初始化段 段名 内容 限制 .bss 全局变量和static变量 不超过64K长度 .ebss 长调用的全局变量和static变量 数据中的任何地方 .stack 栈空间 不超过64K长度 .sysmem malloc函数产生的内存 不超过64K长度 .esysmem far_malloc函数产生的内存 数据中的任何地方 已初始化的段：.text,.cinit,.const,.econst,.pinit和.switch.. .text：所有可以执行的代码和常量 .cinit:全局变量和static变量的C初始化记录， 包含未用const声明的外部（extern）或静态（static）数据表 .const：包含字符串常量和const定义的全局和static变量 .econst：包含字符串常量和初始化的全局变量和static变量（由far const） 的初始化和说明，与.const不同的是.const分配范围被限制在低64K 16位数据区，而.econst的分配范围是4M 22位数据区 .pinit：全局构造器（C++）程序列表,注意是全局的构造器。 .switch：包含大switch段声明的列表。Jump tables for large switch statements。 非初始化的段：.bss,.ebss,.stack,.sysmem,和esysmem. .bss: 为全局变量和局部变量保留的空间，在程序上电时.cinit空间中的数据复制出来并存储在.bss空间中。 .ebss：为使用大寄存器模式时的全局变量和静态变量预留的空间，在程序上电时， cinit空间中的数据复制出来并存储在.ebss中，与.ebss不同的是.bss分配范围被限制在低64K 16位数据区， 而.ebss的分配范围是4M 22位数据区 .stack:为系统堆栈保留的空间，用于和函数传递变量或为局部变量分配空间。 .sysmem:为动态存储分配保留的空间。如果有宏函数，此空间被宏函数占用，如果没有的话，此空间保留为0 .esysmem:为动态存储分配保留的空间。如果有far函数，此空间被相应的占用，如果没有的化，此空间保留为0. ramfuncs: LOAD = FLASHD,表示ramfuncs段的装载在PAGA0的FLASHD中。 RUN = RAML0,表示ramfuncs段的运行地址在PAGE0的RAML0中 LOAD_START(_RamfuncsLoadStart), 令编译器创建了一个变量RamfuncsLoadStart，该变量指向段 ramfuncs的装载地址的首地址。 LOAD_END(_RamfuncsLoadEnd), 令编译器创建了一个变量RamfuncsLoadEnd，该变量指向段ramfuncs的装载地址的末地址。 RUN_START(_RamfuncsRunStart), 令编译器创建了一个变量RamfuncsRunStart，该变量指向段ramfuncs的运行地址的首地址。 解释一下什么叫长调用，指的是程序指令的寻指范围。 上面说了绝对调用的寻指范围是16位数据区，长调用的寻指范围是22位数据区 。 */
