Optimizing C Compiler

dlf — Tue, 16 Feb 2010 01:04:35 GMT

Hi.

The standard and professional edition of codewarrior for DSCs (56800e) have included an optimizer C compiler.

How many the C optimizer is better than compiler without C optimizer. (Maybe any percent or how many times in terms of clock cycles for example??)

I carried out some test. Comparing C code vs. ASM code. In terms of clock cycles, the asm is about twice faster than C. How would be this relationship using C optimizer?

****

How can I update my CodeWArrior special edition v 8.2.3 to 8.3? It is necessary unistall the older version and then install the new 8.3 version? I have not found any patch or update?

*****

Thanks.

AFAIK the special version has the same optimizing C compiler, the only limitation is on code size

just try with or without the optimizations enabled

whit or whitout the optimizations enabled.
You have to enable them in the project preferences (there should be a slide, for different level of optimization).

You can download and install the new version in parallel of the olders.

Thanks.

You're welcome.
