keil C 4
問題(Question)：
板上大大好
小弟最近在寫有關四軸飛行器的控制板
上網參考了CODE
其中有一段程式碼(如下
這段內嵌組合語言似乎是用AT&T的語法寫的
想請問一下如果要轉換為intel的語法
可否教學該如何寫呢?
小弟在程式上還很淺
還請各位大大不吝賜教...
程式碼(Code)：(請善用置底文網頁, 記得排版)
int strcmp(const char *a, const char *b) __attribute__ ((naked));
int strcmp(const char *a, const char *b)
{
__asm__(
"strcmp_lop: \n"
" ldrb r2, [r0,#1] \n"
" ldrb r3, [r1,#1] \n"
" cmp r2, #1 \n"
" it hi \n"
" cmphi r2, r3 \n"
" beq strcmp_lop \n"
" sub r0, r2, r3 \n"
" bx lr \n"
:::
);
}
