expressions. These will get used to reduce clutter as we replace various
calls to createInferredCast and getCast.

llvm-svn: 32191

CastInst and ConstantExpr that allow the signedness to be explicitly passed
in and reliance on signedness removed from getCastOpcode. These are
temporary measures useful during the conversion of inferred casts.

llvm-svn: 32164

llvm-svn: 32113

The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

llvm-svn: 31931

First in a series of patches to convert SetCondInst into ICmpInst and
FCmpInst using only two opcodes and having the instructions contain their
predicate value. Nothing uses these classes yet. More patches to follow.

llvm-svn: 31867

This patch converts the old SHR instruction into two instructions,
AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not
dependent on the sign of their operands.

llvm-svn: 31542

Replace the REM instruction with UREM, SREM and FREM.

llvm-svn: 31369

Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

llvm-svn: 31195

This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

the prototype of the called function.

the right vector of -1's as its operand.

llvm-svn: 24906

llvm-svn: 24200

Add support for specifying alignment and size of setjmp jmpbufs.

No targets currently do anything with this information, nor is it presrved
in the bytecode representation.  That's coming up next.

llvm-svn: 24196

PHI is its only operand.

llvm-svn: 22676

llvm-svn: 22671

prepared to deal with return values that do not dominate the PHI.  If we
cannot prove that the result dominates the PHI node, do not return it if
the client can't cope.

llvm-svn: 22669

llvm-svn: 22666

llvm-svn: 22665

BasicBlock's removePredecessor routine.  This requires shuffling around
the definition and implementation of hasContantValue from Utils.h,cpp into
Instructions.h,cpp
