Reid Spencer 24f1a0e78f The 64-bit constructor for ConstantInt changes from int64_t to uint64_t. 
This caused a warning for construction with -1. Avoid the warning by using
-1ULL instead.

Reid Spencer fad3f247e4 Construct ConstantInt with simpler constructor. 
llvm-svn: 34795
 2007-03-01 19:32:33 +00:00
Reid Spencer 666ea0d046 Use a simpler constructor when constructing ConstantInt. Also, replace 
verbose code to sext/trunc or zext/trunc and APInt with new methods on
that class.

Reid Spencer a127633716 Use a simpler constructor when constructing ConstantInst. 
llvm-svn: 34793
 2007-03-01 19:31:12 +00:00
Reid Spencer d1bbfa5aa6 Drop the ConstantInt(const Type&, const APInt&) constructor. It is 
redundant and more verbose than the ConstantInt(const APInt&) constructor.

Reid Spencer 2f6ad4d3c3 Make the static table of results in sqrt const.

Reid Spencer 6ba8edc789 Fix last night's 445.gobmk breakage which was caused by comparison of 
APInt's of unequal bitwidth.

Reid Spencer 6a44033465 Remove the "isSigned" parameters from ConstantRange. It turns out they 
are not needed as the results are the same with or without it.

Patch by Nicholas Lewycky.

Owen Anderson 3062625451 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.

 2007-02-28 23:31:17 +00:00
Dale Johannesen 962fa8eb9a Changes requested in review of last pass. Also pulled isThumb into a 
member, instead of resetting in every function that uses it.

Reid Spencer d373b9dc59 For PR1205: 
Adjust to changes in ConstantRange interface.

llvm-svn: 34762
 2007-02-28 22:03:51 +00:00
Reid Spencer 9b3d6ec983 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 0286bc1af5 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.

llvm-svn: 34758
 2007-02-28 19:57:34 +00:00
Reid Spencer 8774fe816a 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.

llvm-svn: 34757
 2007-02-28 19:50:21 +00:00
Reid Spencer 56f784d12d For PR1205: 
First round of ConstantRange changes. This makes all CR constructors use
only APInt and not use ConstantInt. Clients are adjusted accordingly.
