C space optimization

[clmp75]

So Im working on this project that is written in C that has a certain space limit on the size of the program. So far I have 15% free. If i use the #peephole, I can get 16% free. I would like to get a lot more space freed up but I am unsure of how to do so. The code itself is fairly optimized for speed and we are using a DSP56k processor. Any suggestions would be appreciated! thank you

Usually, optimizing for speed is at odds with optimizing for size since the larger size usually runs faster by avoiding unnecessary function calls.

I have no suggestions other than goinf though the code and eliminating all extraneous usage, like repetitive literals, unnecessary variables, duplicate code, etc.

Presumably, the code has been through an optimizer.

I got my space freed up a lot more just by changing some of the compiler options. I was using a new program so i was unaware of where some of these options are. Thanks for your help!
