This is the kcc compiler, a one very stupid non retargetable compiler for z80. This compiler is intended to be very simple and suitable for running in small machines (like MSX for example), and let almost part of optimizations for the programmer. After a lot of years seeing compilers for z80 I notice that it is very hard for a C compiler generates a good code for a 8 bit processor like z80, with a expensive indirect addressing mode, so the best solution is to not try that compiler optimize the code and use C as a macro macro assembler. In order to get this last, we need a compiler that does exactly the things we want to do. For example is a variable is register it MUST be register and fails in other case. If a variable is automatic try to realize operations directly with the stack (for example use ADD A,(IX+4), instead of allocate the variable into register add and store again in memory). So if you declare an automatic variable you are a big bullshit or you need it for recursion (static variables are your friends). This is the reason why I begin to develop this compiler, and I hope it will be useful for you.
