这是一个计算某个数阶乘的程序，是在CCS5中用C语言调用线性汇编（混合编程），可是编译通不过（单个文件编译可通过）？请赐教，越详细越好，我是新手，感谢

以下是c语言

#include<stdio.h>
void main()
{
short n=7;
short result;
result=factfunc(n);
printf("factorial=%d",result);
}

以下是线性汇编

.def _factfunc
_factfunc: MV A4,A1
SUB A1,1,A1
LOOP: MPY A4,A1,A4
NOP
SUB A1,1,A1
[A1] B LOOP
NOP 5
B B3
NOP 5
.end

    可能是COFF和ELF格式不兼容的问题
    去掉 _factfunc前面的"_"
    参见 SPRAB90 section 4.1 COFF Underscore Name Mangling

    谢谢，编译运行都可以通过了，但是有如下warning，虽然对结果没影响，可是还是想解决，谢了

    "../factorial.c", line 13: warning #225-D: function declared implicitly

    warning #10210-D: creating ".stack" section with default size of 0x400; use the -stack option to change the default size
    warning #10210-D: creating ".sysmem" section with default size of 0x400; use the -heap option to change the default size

    在cmd文件中加入 

    -heap 0x400

    -stack 0x400  

    即可，提示你堆栈没有初始化长度
