Assuming all goes well, I see this possibly being used as a teaching tool to show the stages of a compiler and how it works. We have discussed some nice optimizations would benefit performance if implemented (keeping AST nodes 64 bits, combining the parser and the verifier, using C enums with shared data in a struct, etc.) and I propose that we do implement these fun changes, but after finish a somewhat complete version of the compiler. Then, we will push this "pure" (slow but straightforward) version of the compiler to a branch that wont change. From there we can move full speed toward optimization. This will allow us to learn how to make a compiler as well as pin the final useful product once were done.
Also to clarify our goals, we are looking to be able to compile a hello world program by the end of this semester (May 2022 or so). As stepping stones for that we will also be able to compile a memcpy.c file which doesn't use the preprocessor and looks something like this:
void* memcpy (void* dest, const void* src, size_t len)
{
char *d = dest;
const char *s = src;
while (len--)
*d++ = *s++;
return dest;
}Long live SACC!
