Re: What's more important optimisations or debugging?

I'm trying to get a feel for what people now consider more important,
optimisations or debugging ability. In the past with such tight memory
limits I would have said optimisations but now with expanded-memory
parts becoming cheaper I would think that debugging ability is more
important in a development tool. It's is not exactly a black and
white question, debug or smallused, but more a ratio. eg. 50% debug/
50% optimised or 70% debug/30% optimised, etc.

The rule is "Make it right, _then_ make it fast." Fast enough is fast
enough. If the optimizer makes your code undebuggable, and you need
the debugger, don't use the optimizer.

That said, I generally set my compiler to optimize for space. It
hasn't really caused me any debugging troubles in at least 5 or 10
years. Of course, most of my debug activity resembles inserting
printf statements rather than stepping through code in an emulator.
YMMV.
