can we say " No. You cannot call a C function from an asm code " ? No, that would be incorrect. Of course you can call a 'C' function from assembler - you can do anything in assembler. The question is, why on earth would you want to do it?!?! As Neil says, if you have a 'C' function in your project, you will also need all the 'C' "baggage" to support it - unless it's a trivial function, in which case why use 'C' anyway?! And if you have to have all the 'C' "baggage" anyhow, what's the point of writing the rest of the code in assembler?! Hence we end up with the "normal" approach of having most of the code in 'C', and just calling assembler function for the bits where 'C' doesn't cut it. |
