nounpl: bottom-up parsers

A bottom-up parser processes the input string from left to right, reducing sequences of symbols to non-terminals according to grammar rules.
Um analisador sintático ascendente processa a cadeia de entrada da esquerda para a direita, reduzindo sequências de símbolos para não-terminais de acordo com as regras da gramática.
2. A compiler component that uses shift-reduce or LR parsing techniques to recognize syntactic structures
Most modern compilers use a bottom-up parser because it can handle a larger class of grammars than top-down parsers.
A maioria dos compiladores modernos usa um analisador sintático ascendente porque pode lidar com uma classe maior de gramáticas do que analisadores sintáticos descendentes.
Bottom-up parsers are fundamental concepts in compiler design taught in computer science programs in both Brazil and the USA.
