I want to run simple analysis on C files (such as if you call foo macro with INT_TYPE as argument, then cast the response to int*), I do not want to prerprocess the file, I just want to parse it (so that, for instance, I’ll have correct line numbers).
Ie, I want to get from
#include <a.h>
#define FOO(f)
int f() {FOO(1);}
an list of tokens like
<include_directive value="a.h"/>
<macro name="FOO"><param name="f"/><result/></macro>
<function name="f">
<return>int</return>
<body>
<macro_call name="FOO"><param>1</param></macro_call>
</body>
</function>
with no need to set include path, etc.
Is there any preexisting parser that does it? All parsers I know assume C is preprocessed. I want to have access to the macros and actual include instructions.
You can have a look at this ANTLR grammar. You will have to add rules for preprocessor tokens, though.
