Hi list. I'm new in the 8051 world and I'm moving from Pic Micro. I have some questions about the options of SDCC.The first is: Why the code generate is a litle bigger than other compilers? I think I don't using the right options of the compiler. But I don't know what can I do. I'm using a Dallas DS89C430, whitout external memory, yust a uC and the crystal. When compile, use: sdcc --xram-size 0 --code-size 0x3FFF --iram-size 128 mysource.c When compile, load the ihx file with boot loader and run. But, the question is: The options pass to sdcc are right? There are other options to minimize code diferent from the optimizer options? The ihx include debug information?
Other question, some compilers have a litle option to make inline functions, this is, the function exist in the code but the binary file generated replace the called function with the real code of the funtion. With this is easy make functions to use hardware device like a timers without add all code needed for the standar functions. SDCC have something like that? I view and test the _naked function but is not the same, with the _naked option the function code is put in other memory space and the "call" is needed to access the functions, this add some code. With the inline functions, the call to the function is repleace with the real code of the function. Is made yust for make the code more easy to read. Thank's Using Tomcat but need to do more?
