--- Comment #8 from Alex Mohr <amohr at amohr dot org> --- (In reply to Jonathan Wakely from comment #5) > A 4x slowdown isn't really acceptable IMHO. At that point, why not just use > -O0 instead? I've been using -O0 for years. I was trying to move to -Og because of this from the manual; particularly the second sentence: "-Og should be the optimization level of choice for the standard edit-compile-debug cycle, offering a reasonable level of optimization while maintaining fast compilation and a good debugging experience. It is a better choice than -O0 for producing debuggable code because some compiler passes that collect debug information are disabled at -O0." I definitely do not want to lose debug info. The speed improvement is a nice bonus, but top-notch debugging is my main goal for my debug builds.
