The default value false places all compiled methods in a log. You must first set the command-line option -XX:+LogCompilation. Places only the specified methods in a log. Sets a breakpoint to stop compilation at the beginning of the specified methods when debugging the JVM. Sets a breakpoint to stop execution at the beginning of the specified methods when debugging the JVM.

See Preventing Duplication with the Enable Option. This option is useful for preventing option duplication.

Automatic code generators – It generates the machine language for a target machine.Hides a directive and renders it unmatchable if it is set to false.

In this, each node of the parse tree is associated with one or more translations. These engines have routines to traverse the parse tree and then produces the intermediate code.

Syntax directed translation engines – It generates intermediate code with three address format from the input that consists of a parse tree.

It generates a finite automaton to recognize the regular expression.

Scanner Generator – It generates lexical analyzers from the input that consists of regular expression description based on tokens of a language.

It is useful as the syntax analysis phase is highly complex and consumes more manual and compilation time.

Parser Generator – It produces syntax analyzers (parsers) from the input that is based on a grammatical description of programming language or on a context-free grammar.Some commonly used compiler construction tools include: These tools assist in the creation of an entire compiler or its parts. The compiler writer can use some specialized tools that help in implementing various phases of a compiler.
