Anton Korobeynikov 666d23d4e6 Implement PR1240 
llvm-svn: 34959
 2007-03-06 05:32:48 +00:00
Reid Spencer d7c6174f85 Make StoreValueToMemory a little more efficient by not copying a 
GenericValue to a temporary.

llvm-svn: 34957
 2007-03-06 05:02:28 +00:00
Reid Spencer b5caad1d5c Make GenericeValue into a struct with a union instead of just a union. This 
allows an APInt value to be constructed. Remove all the native integer types
from the union. These are replaced with the single IntVal of type APInt.

 2007-03-06 03:01:54 +00:00
Devang Patel a8c81c5261 Use std::deque to manage loop queue inside LPPassManager. 
llvm-svn: 34943
 2007-03-06 02:30:46 +00:00
Devang Patel 42dd1e92c7 Keep track of inherited analysis. For example, if a loop pass does not 
preserve dominator info then it should update parent FPPassManager's
available analysis info to reflect this.

llvm-svn: 34942
 2007-03-06 01:55:46 +00:00
Devang Patel d74ede70fb Add preparePassManager() hook. This allows each pass to check whether 
current active pass manager is appropriate or not.

A loop pass may consider current LPPassManager in appropraite if loop
pass is not preserving analysis information that is used by other
passes managed by current LPPassManager. In such situation, loop pass
can pop current LPPassManager from the PMStack using this  hook
and use new LPPassManager for itself.

llvm-svn: 34941
 2007-03-06 01:06:16 +00:00

that the instruction opcode is added to the InstructionVal value and the
consequences of that.

llvm-svn: 34937
 2007-03-05 23:06:32 +00:00
Devang Patel ec2b9a7850 Current pass manager, not the parent pass manager, assumes the role of 
last user when one of the managed pass uses info provided by parent pass
manager.

This was exposed by LPPassManager work.

llvm-svn: 34936
 2007-03-05 22:57:49 +00:00

llvm-svn: 34816
 2007-03-01 22:28:51 +00:00
Reid Spencer 9c61acc450 Add an isUnitValue method for comparison against 1. This just follows a 
common pattern with isNullValue, isAllOnesValue, etc. It also helps to
prevent things like getZExtValue() == 1, which could assert for large
bitwidths.

llvm-svn: 34813
 2007-03-01 21:50:41 +00:00

llvm-svn: 34800
 2007-03-01 20:06:51 +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.

llvm-svn: 34792

 2007-03-01 08:56:24 +00:00
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.

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.

llvm-svn: 34760
 2007-02-28 22:00:54 +00:00
Reid Spencer 3a7e9d8e75 For PR1205:

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.

llvm-svn: 34756
 2007-02-28 18:57:32 +00:00
Jim Laskey c114990526 Provide a more meaningful name.

llvm-svn: 34698
 2007-02-27 22:10:52 +00:00
Reid Spencer 31acef50ad Implement countLeadingOnes() and getMinSignedBits(). This helps to minimize 
the bit width of negative numbers by computing the minimum bit width for a
negative value. E.g. 0x1800000000000000 could be just 0x8000000000000000

 2007-02-27 21:06:57 +00:00
Reid Spencer 70cb5d4287 Improve APInt interface: 
1. Add unsigned and signed versions of methods so a "bool" argument doesn't
   need to be passed in.
2. Make the various getMin/getMax functions all be inline since they are
   so simple.
3. Simplify sdiv and srem code.

Reid Spencer b31bffed96 For PR1205: 
Implement the first step towards arbitrary precision integer support in
LLVM. The APInt class provides arbitrary precision arithmetic and value
representation. This patch changes ConstantInt to use APInt as its value
representation without supporting bit widths > 64 yet. That change will
come after ConstantFolding handles bit widths > 64 bits.

there are no bits to clear (because BitWidth is a multiple of the word size)

Reid Spencer 421bad0dc5 Implement support for non-standard integer bit widths of any size. The 
rules alignment is to pick the alignment that corresponds to the smallest
specified alignment that is larger than the bit width of the type or the
largest specified integer alignment if none are larger than the bitwidth
of the type. For the byte size, the size returned is the next larger
multiple of the alignment for that type (using the above rule). This patch
also changes bit widths from "short" to "uint32_t" to ensure there are
enough bits to specify any bit width that LLVM can handle (currently 2^23);
16-bits isn't enough.

Chris Lattner a0e49f2ead push bytecode decompressor out through APIs. Now the bytecode reader 
api's look like this:

ModuleProvider *getBytecodeModuleProvider(
  const std::string &Filename,  ///< Name of file to be read
  BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer,
  std::string* ErrMsg = 0,      ///< Optional error message holder
  BytecodeHandler* H = 0        ///< Optional handler for reader events
);

This is ugly, but allows a client to say:

  getBytecodeModuleProvider("foo", 0);

If they do this, there is no dependency on the compression libraries, saving
codesize.

to use this mechanism.  This saves one heap allocation and free for each node
of this type that is allocated.  This reduces isel time from 2.7638 to 2.6164s
on kc++, which is a 5.6% speedup.

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.

ConstantFoldInstOperands/ConstantFoldCall to take a pointer to an array
of operands + size, instead of an std::vector.

Devang Patel 1c3633e461 - Undo previous check-in (i.e. Do not export TimingInfo class through 
PassManagers.h).

- Add StopPassTimer() and StartPassTimer() to expose TimingInfo to
CallGraphPassManager

Anton Korobeynikov 037c867b54 Propagate changes from my local tree. This patch includes: 
1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.

NOTEs: 1. Documentation will be updated soon.
       2. llvm-upgrade should be improved to translate csret => sret.
          Before this, there will be some unexpected test fails.
