TMS320C6678: 在CCS5.5中开编译优化-O3后程序崩溃

Part Number: TMS320C6678


您好,基于C6678开发的裸机程序,之前运行正常,在打开了编译优化-O3选项后,仿真运行和烧写到板上运行都会导致程序崩溃,请问如何查找这个问题,还有-O3选项打开时,具体会产生哪些影响,写代码有没有要注意的地方?SPRA666.pdf (Hand-Tuning Loops and Control Code on the TMS320C6000)  SPRU187U.pdf ( TMS320C6000OptimizingCompilerv7.4User'sGuide ) 这两个文档我都看了
