The LL(1) grammar and automatic constructing of LL(1) analysis table
Wen Jing-he · Journal of Shanghai Second Polytechnic University · 2001
The automatic generation of LL(1) grammar analyzer is discussed. In order to make a LL(1) analysis table correctly, the grammar of LL(1) is also discussed. Although the power of LL(1) analysis method is less than LR analysis method, the system resource which is need is far less than the LR analysis method. This method still has the value in practice. The automatic generator which is proposed in this paper can be used not only in demonstrating for teaching ,but also in automatic constructing of LL(1) grammar analyzer which is used in compiler.
