[問題] mac assembly orz...

[allviss8910 (小野豬)]

__asm__ __volatile__("sync\n"
       "0: ldrex %0,0,%2\n\t"  /* load w/ reservation */
       "cmpw %0,%4\n\t"        /* compare against comparand */
       "bne- 1f\n\t"           /* exit if not same */
       "strex. %3,0,%2\n\t"    /* store new_value */
       "bne- 0b\n"             /* retry if reservation lost */
       "1: sync"               /* the exit */
        : "=&r"(result), "=m"(* (int32_t*) ptr)
        : "r"(ptr), "r"(value), "r"(comparand), "m"(* (int32_t*) ptr)
        : "cr0");

有沒有高手可以幫我把它翻成C語言

→ menspower:個人意見...assembly轉C應該很有難度～
→ gn00683155:我一直以為是C轉ASM比較有難度說
推 waynecone:同上!組語轉C比較有難度!向式計算式之類的!
推 mepass:C的敘述式就是很多組語來組成 要拆開不難
推 WolfLord:((!((year)%4)&&(((year)%100)||!((year)%400)))?366:365
→ WolfLord:);  請翻看看 :P
→ MasterChang:這種東西要是簡單，母豬都會飛上天囉...
推 menspower:因為C to Assembly是一對多的關係...反向則是多對一...
推 utility:這是因為c裡插組語才變這樣吧?.看到這種就頭痛
