* Correct the function prototypes for some of the functions to match the
actual spec (int -> uint)
* Add the ability to get/cache the strlen function prototype.
* Make sure generated values are appropriately named for debugging purposes
* Add the SPrintFOptimiation for 4 casts of sprintf optimization:
sprintf(str,cstr) -> llvm.memcpy(str,cstr) (if cstr has no %)
sprintf(str,"") -> store sbyte 0, str
sprintf(str,"%s",src) -> llvm.memcpy(str,src) (if src is constant)
sprintf(str,"%c",chr) -> store chr, str ; store sbyte 0, str+1
The sprintf optimization didn't fire as much as I had hoped:
