Reid Spencer 31acef50ad Implement countLeadingOnes() and getMinSignedBits(). This helps to minimize
the bit width of negative numbers by computing the minimum bit width for a
negative value. E.g. 0x1800000000000000 could be just 0x8000000000000000

Reid Spencer e2eb1fab8c Adjust to changes in the APInt interface.
llvm-svn: 34681
2007-02-27 20:25:25 +00:00
Reid Spencer 70cb5d4287 Improve APInt interface:
1. Add unsigned and signed versions of methods so a "bool" argument doesn't
   need to be passed in.
2. Make the various getMin/getMax functions all be inline since they are
   so simple.
3. Simplify sdiv and srem code.

Reid Spencer ac419b52ad For PR1205:
Implement review feedback:
1. Use new APInt::RoundDoubleToAPInt interface to specify the bit width so
   that we don't have to truncate or extend in constant folding.
2. Fix a pasteo in SDiv that prevented a check for overflow.
3. Fix the shift operators: undef happens when the shift amount is equal
   to the bitwidth.

llvm-svn: 34677
2007-02-27 19:29:54 +00:00

llvm-svn: 34675
2007-02-27 19:22:36 +00:00
Reid Spencer 54abdcf30b 1. Fix three serious bugs in the comparison code.
2. Change RoundDoubleToAPInt to take a bit width parameter. Use that
   parameter to limit the bit width of the result.

llvm-svn: 34673
2007-02-27 18:23:40 +00:00
