[archive] option -Zc

[Migrated content. Thread originally posted on 02 April 2008]

Hello to all,

I'm testing the -Zc option, in project settings, compiler -> miscellaneous options.

"Optimize for smaller code instead of faster code (-Zc)"

Normally, we have active this option, reducing the memory in disk that acu programs need but reducing speed of execution too. At least is what I undestand from the option text. But i deactivate that option and compiling i see that my acu programs goes from 350 kb to 342 kb (for example) in disk space, then... i have doubts... This option really exchange speed for memory in disk and viceversa?

Thanks afterwards

Smaller code instead of faster implies that the codesegment may be reduced. I say may be because it is very code dependent on whether it can be optimized or not.
A program that basically does a lot of file IO will for instance not make much of a difference because the file IO does not leave much room for variations.
Math and string handling are areas in which optimization should make a difference, but again, it is a matter of volume to be able to see significant differences.
I agree however, that it is not exactly what your result is not exactly what you would expect.
I suggest you send it to tech support to get an explanation.

Yeah, we are looking to get an upgrade in speed for our acus, no matter if they grow a bit in disk space, but seeing that they loss size... when they must grow up... i'm a bit lost.

I'll advice the tech team. Thanks Gforseth.
