parser for C -> AST

[richard.melikson]

Hello,

I have to do some analysis of C code. Is it possible to find online a
free parser for C that will generate some kind of syntax tree / AST ?
All I could find is bits and pieces of lex/yacc files that don't
compile, and I tried to look at TCC but its parser is intergrated with
the generator in a stack-based manner, so no AST.

It doesn't have to be C99.

Thanks

Check LCC ( http://www.cs.princeton.edu/software/lcc/ ) and the C
grammars for PCCTS and ANTLR.

free parser for C that will generate some kind of syntax tree / AST ?

c2c (distributed by the cilk project)

look at the bottom of the following page:
http://supertech.csail.mit.edu/cilk/home/software.html
to download it.

some explanations:
http://zoo.cs.yale.edu/classes/cs490/99-00a/bernstein.michael.msb35/node1.html

and may be EiC, a C interpreter. The parser is hand written.

Here is one for SML:

and for OCaml:

Both of the above were made to make it easy to analyse and transform C
programs.
