Hello,

I'm learning LTO and have some questions.
I found the lto/lto.c from gccint.info and add fprintf(...) to output some
message on the terminal, but it shows nothing.
I'not sure whether this is the one that used to optimize code when adding
"-flto" in the command.

Can you give some advice about how the files doing optimize?

Thank you.

Here's an article entitled "How GCC LTO Works", with an example for malloc:
