  快乐虾 http://blog.csdn.net/lights_joy/ lights@hb165.com   本文适用于 ADI bf561 DSP 优视BF561EVB开发板 uclinux-2008r1.5-rc3(smp patch) Visual DSP++ 5.0(update 5)   欢迎转载,但请保留作者信息   有一个错误: [Error ea5004] "../../linux-2.6.x/include/asm/mach-common/context.S":35 Syntax Error in : .macro save_context_with_interrupts syntax error is at or near text 'save_context_with_interrupts'. Attempting error recovery by ignoring text until the ';' 其指向的错误代码为: /*  * Code to save processor context.  *  We even save the register which are preserved by a function call  *   - r4, r5, r6, r7, p3, p4, p5  */ .macro save_context_with_interrupts ……………….      /* Switch to other method of keeping interrupts disabled.  */ #ifdef CONFIG_DEBUG_HWERR      r0 = 0x3f;      sti r0; #else      cli r0; #endif ……………………… .endm 这里有两个问题,首先是vdsp的汇编器不支持.macro,只能用#define来替代,第二个是在里面出现了#ifdef这样的条件判断,只能将之移到宏定义的外面,修改后的代码为: #ifdef CONFIG_DEBUG_HWERR   #define save_context_with_interrupts               / ………………..                   /      /* Switch to other method of keeping interrupts disabled.  */                  /      r0 = 0x3f;                  /      sti r0;                / ……………….               / //.endm   #else   #define save_context_with_interrupts               / ………………………..                 /      /* Switch to other method of keeping interrupts disabled.  */                  /      cli r0;                / ………………………..                 / //.endm   #endif // CONFIG_DEBUG_HWERR 其它宏的修改与此类似。
