As86 assembly is only used to compile the boot/bootsect. s boot Sector Program in the kernel and the setup program boot/setup. s in the real mode. All other assembly language programs in the kernel (including C language compilation programs) are compiled using gas and linked to the modules produced by C language compilation.

selector allows you to position an element based on an attribute. You can specify only one of the attributes of the element, so that all use that property regardless of its value, this element will be positioned, or it can be more explicit and locate the elements that use specific values on those properties, which is where the property selector demonstrates their power.The description is as follows:Browser support:

the filter element has a certain attribute, such as the href attribute of a. the attribute selection tends to be determined by the attribute value.
For example, a href = "Google.com" and a href = "www.google.cn"If a [href * = Google] is used for determination, both of them match;If a [href $ = cn] is used for determination, www.google.cn is returned.If a [href ^ = WWW] is used for determination, Google.com is returned.
Principle:
ATT * = VAL: the val
Differences between ATT assembly and intel assembly:1. ATT has a more complex way of writing instant numbers, variables ($), and registers (%. Intel directly uses it.2. the Source and Destination operands of ATT are opposite to those of intel.3. Addressing ATT uses the segment address: (offset, base address, factor) wh
The differences between att and Intel assembly syntax are as follows:
1) att uses $ to represent the immediate number, while Intel's immediate number does not need to be defined.
2) att prefixed the register name with %, but intel did not.
3) att syntax uses the opposite sequence to process source and target operand

In IE8, the substring matching attribute selector (substring matching attribute selectors) is added in CSS3. The matching rules are similar to those in Regular Expressions:
E [att ^ = 'val'] // The substring starts with 'val'E [att $ = 'val'] // The substring ends with 'val'E [
