Just curious to know. Is there any real world application/product where this will help? Can you give more context to this requirement. Regards, Kannan -----Original Message----- From: gcc-ow...@gcc.gnu.org [mailto:gcc-ow...@gcc.gnu.org] On Behalf Of Satya Prakash Prasad Sent: Tuesday, June 12, 2012 12:05 PM To: Ian Lance Taylor Cc: gcc@gcc.gnu.org Subject: Re: GCC Making a new PASS Thanks to all my issue got resolved. I placed the code in 'if block' checking cfun is NULL or not and removed gcc_assert. It worked fine for me. My idea is to print the lines of source code gcc is compiling. Further to that I want to update the statement with statement ; print("%s %d\n", __FILE__, __LINE__); So that when program is running I know which file which line of my program is getting executed. I tried printing statements in pass_remove_useless_stmts pass but I think these are internal GCC stages. I see statements of code like: if (D.3886 > 0) { D.3887 = obj->funcs; D.3888 = D.3887->close; D.3886 = obj->next_input; D.3888 (obj, D.3886); } So please let me know how can I achieve the objective and which pass should I make use of?
