MDK5包含asmdefs.h这个头文件出错。

//*****************************************************************************
//
// The defines required for RV-MDK.
//
//*****************************************************************************
#ifdef rvmdk

//
// The assembly code preamble required to put the assembler into the correct
// configuration.

preserve8

//

#define __IMPORT__ import
#define __LABEL__
#define __STR__ dcb
#define __THUMB_LABEL__
#define __WORD__ dcd

#endif // rvmdk

主要报错提示

thumb
require8
preserve8 这三个未定义。请问这个怎么解决？

    1.你用的是什么芯片

    2.头文件加载对了没

    3.你看看这三个变量在哪里定义的了,全局搜索下看看

    用的TM4C123GH6PMI，全局搜不到，肯定是没定义，看英文注释这边几句需要自己修改的，但是怎么修改，请TI技术人员出来给个解决方案吧，还是这个头文件有啥用，不包含可以吗。

    asmdefs.h，从字面上看，应该是汇编代码的宏定义，该头文件的介绍，在头文件开头就有了

    从内容看，是汇编指令的宏定义

    #define __ALIGN__               .balign 4
#define __END__                 .end
#define __EXPORT__              .globl
#define __IMPORT__              .extern
#define __LABEL__               :
#define __STR__                 .ascii
#define __THUMB_LABEL__         .thumb_func
#define __WORD__                .word
