Hello ! I have a problem which I can't resolve. I wrote program for 89C2051 for one of my friend in Basom Basic compiler (http://www.mcselec.com). Compiled code was about 1945 bytes. Since I prefer C, I transalte Bascom basic to C. But when I compile, generated code was 2313. I try to change optimization parameters, but generated code never go below 2313. Even bigger. Where am I wrong ? Is it possible that stupid Basic make smaller code tne best C compiler ? Then I find out that this code: while (1) { printf ("Hello World\n"); } generate fully 1093 bytes (!) for Atmel 89C2051. 1093 bytes???? Three lines? Same program in Bascom generate only 154 (!) bytes. When I remove all "printf" from my C code, generated code was arond 2200 byte. But, with same action in Basic code (remove all "print") 1340 bytes long code. Exactly same program in Keil C and Bascom basic generate 860 byte smaller code ! I don't belive this. Do I have to program in (stupid) Basic if I want smaller code ? I still belive I did mistake somewhere, so I need help. I will send both C and basic code for interested people. With best regards !
"I faced a problem of having a project which had to include some 'reference code' that could not be changed. Of course, it was full of printf() statements. My solution was to write my own printf() function that included just the required features." I'm curious about this - if you replace the library printf() calls with your own version of printf() you have modified your reference code. Stefan
