The code example has two interrupt functions isr_counter_rollover() and isr_compare_match() which are both trying to use the TIMER0_A0_VECTOR. This explains why the linker reports the "Symbol __TI_int55 has already been defined" error. The code looks to...
1、数据类型Symbol 1.1 初识Symbol 在ES6之前,只有6种数据类型 Number、String、Boolean、Undefined、Null、Obje ES6新增了一种原始的数据类型 ——Symbol(符号),表示独一无二、不可变的值,它的出现就是因为对象属性名都是字符串容易造成属性名冲突,为确保对象属性使用唯一的标识符,不会发生属性冲突的危险 Smybol实...

A symbol, such as an option or command, having one or more fixed names in a command line interface.
If a symbol with the same name has already been encountered from a previous input file, a symbol resolution process is called. This resolution process determines which of two entries from relocatable objects are kept. This resolution process also determines how external references to shared object ...
Returns a NamespaceSymbol representing the global (root) namespace, with module extent, that can be used to browse all of the symbols defined in this module. HasUnsupportedMetadata Indicates that this symbol uses metadata that cannot be supported by the language. Examples include: Pointer types...

Here, an−1 has been used as shorthand for the repetition of ‘a’ n−1 times. There is still at least one non-terminal symbol in the right-hand side. We would need to use the second rule S→ab to obtain S⇒*anbn We can see that the language consists of a number of ‘a...
