GCC Making a new PASS

I am trying to write a new GCC pass in gcc-4.1.2. This is my first attempt and I am trying to print lines of code for a function gcc is compiling. So I added the below code. Note if I remove code in execute_gimple_manipulation method the issue does not occur : gcc/gcc-4.1.2 1223> cat gcc/gimple-ma

builtin_strncat/builtin_strcat reads memory pointed to by the first argument?

Hi, In "ref_maybe_used_by_call_p_1", the comment says "strcat/strncat additionally reads memory pointed to by the first argument." I do not understand these words well, why the first string is read by the two functions? Thanks for help. -- Best Regards.
