    Phoronix: New "-O1g" Optimization Level Proposald For GCC Compiler

    A new "-O1g" optimization level has been proposed for the GNU Compiler Collection that would allow better performance but still relative ease for debugging the generated binaries...

    Perhaps they should fix -Og first? In particular an option for https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78685 would be nice. But Og has many issues ( https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82738), and another unmaintained optimization option wouldn't help.

    EDIT: Oops.. He actually adresses that in a follow up patch https://gcc.gnu.org/ml/gcc-patches/2.../msg01394.html Great then

      @Michael: typo in title? Or is there a verb "to proposal"?

          We always had troubles with -Og (during a gdb session) and had to revert to -O0 -g
