Other than lex/yacc

Hi,

I am looking for clean and efficient lexical/parser tool which generates
(abstract) syntax trees, symbol table information and easily manipulatable
intermediate form. It would be great if the tool allows handling
assertions/comments also.

I intend to derive verification conditions for the input program ( may be in
written in C,Java, or my own toy language).

Any thing other than Lex/Yacc.

regards

This is definitely not Lex/Yacc:

http://www.dmitry-kazakov.de/ada/components.htm

It contains a parser for infix expressions capable to generate syntax
trees. No grammar required, (well, you need not to lay it down (:-))

I feel I have to mention the Prolog programming language.

A free interpreter (which I can recommend) and tutorial are to be
found at:

http://www.amzi.com

but there are many other Prolog resources on the web.

I am considering using Prolog for my own purposes, for much the same
reasons you cite. It is not a parsing tool as such, but it is
readily programmed to do parsing (to generate trees) and tree
manipulations. Prolog can be used interactively, and structures are
easily played with. Just a thought.

The DMS Software Reengineering Toolkit meets all of these
requirements. It has front ends including full symbol table
construction for C, C++, COBOL and Java. The ASTs are directly
manipulable via source to source transformations or analyzable via
attribute evaluation. See
