for pointing out these errors.

535c619e2b WHILE does not "pop" a value, it "examines" to top of stack. Make this 
clear in the applicable comment.

58b563ce43 * 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:

691ef2ba06 Implement count leading zeros (ctlz), count trailing zeros (cttz), and count 
population (ctpop).  Generic lowering is implemented, however only promotion
is implemented for SelectionDAG at the moment.

More coming soon.

9974ddab2b Avoid garbage output in the statistics display by ensuring that the 
strings passed to Statistic's constructor are not destructable. The stats
are printed during static destruction and the SimplifyLibCalls module was
getting destructed before the statistics.

  fprintf(F,"%c",'x') -> fputc('c',F)
