注：本文是作者以前發(fā)表在其個(gè)人博客，現(xiàn)在發(fā)布到“聚豐開(kāi)發(fā)”專(zhuān)欄

有個(gè)項(xiàng)目需要分析ARM THUMB指令的機(jī)器碼，網(wǎng)上沒(méi)有搜索到整理好的機(jī)器碼表，只好自己把相關(guān)指令的機(jī)器碼歸納整理出來(lái)，這里分享給大家。THUMB指令并不多，只有六十多條，這個(gè)數(shù)字真的是非常了不起，51都一百三十多條呢。

可能這張表對(duì)于大多數(shù)朋友都用不到，畢竟要深入到機(jī)器碼這一層的機(jī)會(huì)還是比較少，我想能到這一步的朋友一定對(duì)ARM指令有了足夠的理解，所以就不對(duì)注釋做另外的說(shuō)明，相信你一看就懂。

呵呵，如果你用上了這張表，記得在內(nèi)心感謝我一下，這可是我從《Addison Wesley - ARM Architecture Reference Manual (2nd Edition)》中一條一條摘錄出來(lái)的。


v is immed_value
n is Rn
m is Rm
