Reid Spencer ab0e08ae2f Whoops, last word with bits in large shift left wasn't correct.

from README.
When no water available, use end of block if in range.  (More to do here.)

Reid Spencer 468ad911cb Fix the remainder shifting in KnuthDiv. 
llvm-svn: 34562
 2007-02-24 20:38:01 +00:00
Reid Spencer 632ebdf8bd 1. Fix a bug in fromString for the <= 64bits case 
2. Fix shl when shiftAmount == BitWidth.

llvm-svn: 34560
 2007-02-24 20:19:37 +00:00
Reid Spencer df6cf5ab71 1. Fix last bug in KnuthDiv. All divide tests pass up to 1024 bits now. 
2. Clean up comments, style, coding standards, etc.
3. Simplify a constructor.

Extended testing revealed some additional bugs in shifting. I'll fix these
tomorrow.

llvm-svn: 34559
 2007-02-24 10:01:42 +00:00
Reid Spencer 8fe5240289 Improve documentation. 
Make divide function internal (it was briefly external for testing).

llvm-svn: 34556
 2007-02-24 09:45:44 +00:00
Jim Laskey b869ab6f31 Drop unused operand. 
llvm-svn: 34555
 2007-02-24 09:44:17 +00:00
Reid Spencer a5e0d200c9 1. Make internal functions take const arguments where they should, just 
to be safe.
2. Make internal functions that return a carry/borrow return bool instead
   of uint64_t because the carry/borrow can only be in range [0,1].
3. Assert that the pointers to KnuthDiv are all different so that the
   result and operands can't overlap.
4. Add debug output to KnuthDiv function.
5. Fix a problem with KnuthDiv by separating the b's complement operation
   from the subtraction borrow operation. This fixes a wide range of
   division problems, but alas, not all of them.
