att dongle

Recently, a key part of the C language algorithm needs to be implemented in assembly language. In Linux, ATT assembly is basically used for Embedded Assembly. For example, ATT assembly is used for Linux system startup. I have studied ATT assembly before, but I have forgotten it after a while, but I am familiar with Intel assembly basics. The two are basically sim

simultaneously. Separate E and F with commas (,). 6. E F The descendant element selector matches all f elements belonging to the descendant of the Eelement. E and F are separated by spaces. 7. E> F Child element selector, matching the child element F of all eElements 8. E + F Adjacent to the element selector, matching all elements of the same level F that follow the Eelement Instance: Div P {color: # f00 ;} # Nav Li {display: inline ;} # Na

element, such as p: first-of-type, is the first of all the child elements of the p type. It is no longer the first child element, as long as it is the first element of this type. Attention: of course, these elements belong to the same level, that is, their peers. The same type of selector: last-child and: last-of-type,: nth-child (n) and: nth-of-type (n) can also be understood in this way. [Attribute selector]Version description E [att]CSS2 select an

1. In intel format, most of them use upper-case letters (both in lower case) and lower-case letters in att format. 2. In att format, Register names must be prefixed with "%", which is not required in intel. 3. The original operation of the command is different from that of the destination operand. For example, if the eax value is passed into the EBX command, in Intel, the target is in the front, and the
