Disabling optimization in certain areas

Luigi — Tue, 19 Feb 2008 23:19:52 GMT

Hi all,

I am using CW for the 9S08AW32 processor. I want copyright information to be part of the executable code as data. So, I have an array of characters for copyright information declared as "const char Copyright[] = { "Copyright 2008 ... All rights reserved." }; The problem comes in when the compiler wants to optimize Copyright out since it is not used. So, to get around the problem, I have a statement in main, "errorcode = Copyright[0];". My question: is there a way to tell the compiler to NOT optimize out the Copyright variable without using the assignment I made above? Thanks.

Lou

You can tell the linker to consider your object as "root" when building the dependency information. Add the following snippet to your .prm file to do that:

DEPENDENCY
ROOT Copyright END
END

Alternatively, you can add an "ENTRIES" block to your .prm file:

ENTRIES
Copyright
END

Thanks! I will give those a try. I know it's no big deal to just leave the assignment statement in there, but I thought there must be a cleaner way of doing it. Appreciated.
