Even though many developers use it, this mode is not intended for development, it is production level and should be run once (or at leas a limited number or times), when the developers are sure that everything is fine in the debug mode. As Victor previously said, we should have all the good stuff (PGO, LTO, etc) enabled by default, regardless the time needed to do it. I use it all the time in development: - For running math tests that would be too slow otherwise. - To diagnose invalid accesses that only occur with -O2. - To speed up Valgrind runs.

Even though many developers use it, this mode is not intended for development, it is production level and should be run once (or at leas a limited number or times), when the developers are sure that everything is fine in the debug mode. As Victor previously said, we should have all the *good* stuff (PGO, LTO, etc) enabled by default, regardless the time needed to do it.

I use it all the time in development:

  - For running math tests that would be too slow otherwise.

  - To diagnose invalid accesses that only occur with -O2.

  - To speed up Valgrind runs.
