b0a7bfa105 Use a simpler constructor when constructing ConstantInst.

b4e877c488 Drop the ConstantInt(const Type&, const APInt&) constructor. It is 
redundant and more verbose than the ConstantInt(const APInt&) constructor.

18d663b62c Fix last night's 445.gobmk breakage which was caused by comparison of 
APInt's of unequal bitwidth.

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
 2007-02-28 22:02:48 +00:00
Reid Spencer
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.

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.

 2007-02-28 18:35:36 +00:00

d8c7e8999e bugfix: fastcall does not require the first two params to be marked 'inreg', 
they always get registers.

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

d91c898cc0 Make the trunc/sext/zext methods return APInt& so that these operations 
can be chained together with other operations.

llvm-svn: 34743
 2007-02-28 17:34:32 +00:00
Reid Spencer
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.
