| I just noticed the following in the description for the "Instruction Scheduling" build setting:
Optimize instruction scheduling for this CPU. Generated code will run on older processors. Only applies to GCC 3.3. [GCC_MODEL_TUNING, -mtune=<cpu>] (emphasis mine)
Does this really only apply to GCC 3.3 and not GCC 4.0? Or should that read "Only applies to GCC 3.3 and later"? I also noticed the same thing for "Use 64-bit Integer Math." That setting also says that it "Only applies to GCC 3.3." Is this really the case for these settings? Do they really not work under GCC 4.0? And if so, then why?
I'm hoping this is just a typo.
I just did a search of all of the settings for "Only applies" and "Fix & Continue" as well as "Incomplete Objective-C Protocols" also say that they only apply to GCC 3.3. So I'm guessing that the descriptions for these settings just weren't updated to say "Only applies to GCC 3.3 and later." Can anyone confirm this?
Thanks! _____________________________
