Fix build error.

llvm-svn: 36648

Do not use typeinfo to identify pass in pass manager.

llvm-svn: 36632

Revert last patch. It was already fixed.

llvm-svn: 36102

For PR1336:
Fix a div-by-zero bug noticed by APInt. This fixes:
test/Transforms/IndVarsSimplify/exit_value_tests.llx

llvm-svn: 36099

Fix a nasty bug introduced when apint'ified. This fixes
Transforms/IndVarsSimplify/exit_value_tests.llx

llvm-svn: 36081

Eliminate unnecessary APInt construction.

llvm-svn: 35740

Make APInt variables do the computation stuffs instead of
ConstantExpr::getXX if possible.

llvm-svn: 35738

Eliminate unnecessary zext/trunc stuffs.

llvm-svn: 35737

Treat xor of signbit like an add.

llvm-svn: 35586

Guard further against APInt operations with operands of unequal bit width.

llvm-svn: 34897

Fix an unequal bitwidth issue.

llvm-svn: 34831

Prefer non-virtual calls to ConstantInt::isZero over virtual calls to
Constant::isNullValue() in situations where it is possible.

llvm-svn: 34821

Make it possible to create an SCEVUnknown from an APInt as well as an int.

llvm-svn: 34816

Construct ConstantInt with simpler constructor.

llvm-svn: 34795

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

llvm-svn: 34790

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.

llvm-svn: 34782

APIntify various computations in ScalarEvolution

llvm-svn: 34780

For PR1205:
Make GetConstantFactor compute its result using an APInt.

llvm-svn: 34765

For PR1205:
Adjust to changes in ConstantRange interface.

llvm-svn: 34762

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

llvm-svn: 34758

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

Changes to support making the shift instructions be true BinaryOperators.
This feature is needed in order to support shifts of more than 255 bits
on large integer types. This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
shl i32 %X, 1
instead of
shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

The local "ConstantFold" method is now just a watered down version of
ConstantFoldInstOperands. Switch to ConstantFoldInstOperands and remove
ConstantFold.

llvm-svn: 33683

adjust to constant folding api changes.

For PR1043:
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.
