503dda5840 Make getNumWords public so that those using getRawData stand a chance of 
not reading beyond the end of the buffer returned.

53a673b3ed Add a non-virtual test for zero, isZero, and rename isUnitValue isOne. 
These will be used in upcoming patches to avoid virtual function call when
the client knows it is a ConstantInt.

2ce72a4bd8 Add an isUnitValue method for comparison against 1. This just follows a 
common pattern with isNullValue, isAllOnesValue, etc. It also helps to
prevent things like getZExtValue() == 1, which could assert for large
bitwidths.

b4e877c488 Drop the ConstantInt(const Type&, const APInt&) constructor. It is

3f3487918c Remove the "isSigned" parameters from ConstantRange. It turns out they 
are not needed as the results are the same with or without it.

cbbf9aa6b0 Use the GCC built-in for PopulationCount when it's available, and use a faster 
algorithm when it's not.  This should be particularly noticeable in the
64-bit case.

f119927a6f Move ConstantRange class to lib/Support from lib/Analysis and make its 
interface not depend on Type or ICmpInst.

llvm-svn: 34761

f632e1cd14 Provide an ICmpInst::makeConstantRange to generate a ConstantRange value 
from a predicate and an APInt. This is removed from ConstantRange class
so that ConstantRange doesn't have to depend on lib/VMCore.

965067a054 For PR1205: 
Remove ConstantInt from ConstantRange interface and adjust its users to
compensate.

a9d0cc903b Implement a convenience method to construct a ConstantInt directly from an 
APInt. The implied type is the integer type that corresponds to the bit
width of the APInt.

e2b4631435 For PR1205: 
First round of ConstantRange changes. This makes all CR constructors use
only APInt and not use ConstantInt. Clients are adjusted accordingly.

2b933467ad For PR1205: 
Convert ConstantRange class to use APInt internally as its value type for
the constant range, instead of ConstantInt.

llvm-svn: 34745
 2007-02-28 17:36:23 +00:00

0f2d45e42c Make APInt a little more friendly to its users: 
* Add support for + and - of a uint64_t.
  * Make trunc/sext/zext return *this so it can be chained with other ops
  * Add smin, smax, umin, umax functions for getting min/max values.

edbe747bab 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
