Hi:
我想我遇到一个SDCC关于除法取余运算的BUG。
I think I came across an SDCC bug about the divide operation.
测试代码如下
Test code is as follows：
void modtest2(unsigned int t)
{
while(t != 0){
t % 10;
printf("t = %d, mod10 = %d\r\n", t, t%10);
t = t / 10;
}
}
void mod_test(void)
{
static unsigned int t = 1000;
modtest2(t);
}
问题应该是当执行除法运算后，再次执行取模运算，取模得到的结果不正确。
The problem may be that after performing the division operation, the modulo
operation is performed again, and the result obtained by modulo is incorrect.
以上代码测试结果如下：
the test result is as follows:
t = 2943, mod10 = 3
* t = 294, mod10 = 72
t = 29, mod10 = 9
t = 2, mod10 = 2
t = 2944, mod10 = 4
* t = 294, mod10 = 6
t = 29, mod10 = 9
t = 2, mod10 = 2
* 号标记的行，得到了错误结果
The line marked by "*" is incorrect.
Sorry for my pool English，the English is translated by Google.
