Nick Lewycky 92db8e8e39 ConstantInt has some getters which return ConstantInt's or ConstantVector's of 
the value splatted into every element. Extend this to getTrue and getFalse which
by providing new overloads that take Types that are either i1 or <N x i1>. Use
it in InstCombine to add vector support to some code, fixing PR8469!

 2011-02-15 00:14:00 +00:00
Chris Lattner 34442e6ebf revert my ConstantVector patch, it seems to have made the llvm-gcc 
builders unhappy.

llvm-svn: 125504
 2011-02-14 18:15:46 +00:00
Chris Lattner d9f5b88548 Switch ConstantVector::get to use ArrayRef instead of a pointer+size 
idiom.  Change various clients to simplify their code.

llvm-svn: 125487
 2011-02-14 07:55:32 +00:00
Chris Lattner 603af18826 make ConstantExpr::replaceUsesOfWithOnConstant preserve the inbounds 
flag.  Noticed by Jin Gu Kang!

llvm-svn: 125366
 2011-02-11 05:37:21 +00:00
Chris Lattner 94c8d2941f make the constantexpr interfaces for inbounds GEPs follow the same style 
as other constantexpr flags, reducing redundancy.

llvm-svn: 125365
 2011-02-11 05:34:33 +00:00
Chris Lattner e9b4ad7391 switch the constantexpr, target folder, and IRBuilder interfaces 
for NSW/NUW binops to follow the pattern of exact binops.  This
allows someone to use Builder.CreateAdd(x, y, "tmp", MaybeNUW);

llvm-svn: 125270
 2011-02-10 07:01:55 +00:00
Chris Lattner 0d75eac350 refactor ConstantExpr interfaces a bit around "exactness".

Chris Lattner e17322b3b7 fix comment change.

 2011-02-07 20:03:14 +00:00
Chris Lattner a676c0fc77 implement .ll and .bc support for nsw/nuw on shl and exact on lshr/ashr. 
Factor some code better.

llvm-svn: 125006
 2011-02-07 16:40:21 +00:00
Chris Lattner 35315d065b enhance vmcore to know that udiv's can be exact, and add a trivial 
instcombine xform to exercise this.

Nothing forms exact udivs yet though.  This is progress on PR8862

Duncan Sands cf0ff030a8 Have m_One also match constant vectors for which every element is 1.

Jay Foad 9f32cfd35e Fix indentation. 
llvm-svn: 124375
 2011-01-27 14:44:55 +00:00
Jay Foad 1d4a8fe156 Remove casts between Value** and Constant**, which won't work if a 
static_cast from Constant* to Value* has to adjust the "this" pointer.
This is groundwork for PR889.

Chris Lattner 13ee795c42 remove unions from LLVM IR. They are severely buggy and not 
being actively maintained, improved, or extended.

Oscar Fuentes 40b31ad3ee Prefix `next' iterator operation with `llvm::'.

Benjamin Kramer 3d4af4e91e Preallocate vector, avoid unnecessary vector growth. 
llvm-svn: 109971
 2010-08-01 11:43:26 +00:00
Chris Lattner 718da70ca2 Fix PR7658, a problem where type refinement can trigger 
constant replacement which was botching its handling of
types.  Use of getType() instead of getRawType() was causing
the type map in constant folding to be updated wrong.

Dan Gohman a2414ea190 Remove the API compatibility layer which converted add, sub, and mul 
to fadd, fsub, and fmul, when used with a floating-point type. LLVM
has supported the new instructions since 2.6, so it's time to get
on board.

llvm-svn: 102971
 2010-05-03 22:44:19 +00:00
Dan Gohman 3cdcc3f728 Simplify this code.

llvm-svn: 99564

Talin 1feba3c980 replaceUsesOfWithOnConstant implementation for unions. 
llvm-svn: 96616
 2010-02-18 21:43:45 +00:00
Duncan Sands 19d0b47b1f There are two ways of checking for a given type, for example isa<PointerType>(T) 
and T->isPointerTy().  Convert most instances of the first form to the second form.
Requested by Chris.

llvm-svn: 96344
 2010-02-16 11:11:14 +00:00
Duncan Sands 9dff9bec31 Uniformize the names of type predicates: rather than having isFloatTy and 
isInteger, we now have isFloatTy and isIntegerTy.  Requested by Chris!

llvm-svn: 96223
 2010-02-15 16:12:20 +00:00
Chris Lattner 392be58cad Add support for a union type in LLVM IR. Patch by Talin!

Duncan Sands fa5f5965de Adding missing methods for creating Add, Mul, Neg and Sub with NUW. 
llvm-svn: 95086

Chris Lattner f5edeebd8c eliminate a bunch of pointless LLVMContext arguments. 
llvm-svn: 95001

Dan Gohman de047f2051 Add a getNUWMul function. 
llvm-svn: 94982
 2010-02-01 16:38:14 +00:00
Dan Gohman ede94e6850 Add a generalized form of ConstantExpr::getOffsetOf which works for 
array types as well as struct types, and which accepts arbitrary
Constant indicies.  

llvm-svn: 94981
 2010-02-01 16:37:38 +00:00
Dan Gohman a9be73929f Make getAlignOf return an i64, for consistency with getSizeOf and 
getOffsetOf, and remove the comment about assuming i8 is byte-aligned,
which is no longer applicable.

llvm-svn: 94738
 2010-01-28 02:43:22 +00:00
Dan Gohman cf9138307d Remove SCEVAllocSizeExpr and SCEVFieldOffsetExpr, and in their place 
use plain SCEVUnknowns with ConstantExpr::getSizeOf and
ConstantExpr::getOffsetOf constants. This eliminates a bunch of
special-case code.

Also add code for pattern-matching these expressions, for clients that
want to recognize them.

Move ScalarEvolution's logic for expanding array and vector sizeof
expressions into an element count times the element size, to expose
the multiplication to subsequent folding, into the regular constant
folder.

Chris Lattner 37bc78a5e2 fix CastInst::castIsValid to reject aggregate types, fixing PR6153: 
llvm-as: t.ll:1:25: error: invalid cast opcode for cast from '[4 x i8]' to '[1 x i32]'
@x = constant [1 x i32] bitcast ([4 x i8] c"abcd" to [1 x i32])

Nick Lewycky 9e26c1cc0c Fix a crasher trying to fold each element in a comparison between two vectors 
if one of the vectors didn't have elements (such as undef). Fixes PR 6096.

Fix an issue in the constant folder where fcmp (<2 x %ty>, <2 x %ty>) would
have <2 x i1> type if constant folding was successful and i1 type if it wasn't.
This exposed a related issue in the bitcode reader.

Chris Lattner a7cfc43af8 differences between two blockaddress's don't cause a 
global variable initializer to require relocations.
