9258cd3994 Use the new architecture to get the containing machine basic block for a machine 
instruction. Also, use "splice" to move the new instruction instead of
remove/insert (where it was leaking memory anyway).

e138b3dd1f switch the register iterator to act more like hte LLVM value iterator: dereferencing 
it now returns the machineinstr of the use.  To get the operand, use I.getOperand().

Add a new MachineRegisterInfo::replaceRegWith, which is basically like
Value::replaceAllUsesWith.

operands.  The lists are currently kept in MachineRegisterInfo, but it does
not yet provide an iterator interface to them.

6410552250 Fix a problem where lib/Target/TargetInstrInfo.h would include and use 
a header file from libcodegen.  This violates a layering order: codegen
depends on target, not the other way around.  The fix to this is to 
split TII into two classes, TII and TargetInstrInfoImpl, which defines
stuff that depends on libcodegen.  It is defined in libcodegen, where 
the base is not.

84bc5427d6 Rename SSARegMap -> MachineRegisterInfo in keeping with the idea 
that "machine" classes are used to represent the current state of
the code being compiled.  Given this expanded name, we can start 
moving other stuff into it.  For now, move the UsedPhysRegs and
LiveIn/LoveOuts vectors from MachineFunction into it.

Update all the clients to match.

This also reduces some needless #includes, such as MachineModuleInfo
from MachineFunction.

8aa797aa51 Add new shorter predicates for testing machine operands for various types: 
e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.

f73823000e More cleanups for MachineOperand: 
- Eliminate the static "print" method for operands, moving it
    into MachineOperand::print.
  - Change various set* methods for register flags to take a bool
    for the value to set it to.  Remove unset* methods.
  - Group methods more logically by operand flavor in MachineOperand.h

e3087890ac MachineOperand: 
- Add getParent() accessors.
  - Move SubReg out of the AuxInfo union, to make way for future changes.
  - Remove the getImmedValue/setImmedValue methods.
  - in some MachineOperand::Create* methods, stop initializing fields that are dead.

MachineInstr:
  - Delete one copy of the MachineInstr printing code, now there is only one dump
    format and one copy of the code.
  - Make MachineOperand use the parent field to get info about preg register names if
    no target info is otherwise available.
  - Move def/use/kill/dead flag printing to the machineoperand printer, so they are
    always printed for an operand.

6259d51c91 If we have a load of a global address that's not modified during the 
function, then go ahead and hoist it out of the loop. This is the result:

$ cat a.c
volatile int G;

int A(int N) {
  for (; N > 0; --N)
    G++;
}
$ llc -o - -relocation-model=pic
_A:
...
LBB1_2: # bb
        movl    L_G$non_lazy_ptr-"L1$pb"(%eax), %esi
        incl    (%esi)
        incl    %edx
        cmpl    %ecx, %edx
        jne     LBB1_2  # bb
...
$ llc -o - -relocation-model=pic -machine-licm
_A:
...
        movl    L_G$non_lazy_ptr-"L1$pb"(%eax), %eax
LBB1_2: # bb

        incl    %edx
        cmpl    %ecx, %edx
        jne     LBB1_2  # bb
...

I'm limiting this to the MOV32rm x86 instruction for now.

ff26ab2277 Don't break critical edges for single-bb loops, this helps with PR1877, though 
it is only a partial fix.  This change is noise for most programs, but
speeds up Shootout-C++/matrix by 20%, Ptrdist/ks by 24%, smg2000 by 8%,
hexxagon by 9%, bzip2 by 9% (not sure I trust this), ackerman by 13%, etc.

OTOH, it slows down Shootout/fib2 by 40% (I'll update PR1877 with this info).

0e13821c96 GC poses hazards to the inliner. Consider: 
define void @f() {
            ...
            call i32 @g()
            ...
    }

    define void @g() {
            ...
    }

The hazards are:

  - @f and @g have GC, but they differ GC. Inlining is invalid. This
    may never occur.
  - @f has no GC, but @g does. g's GC must be propagated to @f.

The other scenarios are safe:

  - @f and @g have the same GC.
  - @f and @g have no GC.
  - @g has no GC.

This patch adds inliner checks for the former two scenarios.

d9d70395d9 Get the verifier to check attributes on calls as well 
as on functions.  Make it verify invokes and not just
ordinary calls.  As a (desired) side-effect, it is no
longer legal to have call attributes on arguments that
are being passed to the varargs part of a varargs
function (llvm-as drops them on the floor anyway).

110c835039 Make DAE not wipe out attributes on calls, and not drop 
return attributes on the floor.  In the case of a call
to a varargs function where the varargs arguments are
being removed, any call attributes on those arguments
need to be dropped.  I didn't do this because I plan to
make it illegal to have such attributes (see next patch).
With this change, compiling the gcc filter2 eh test at -O0
and then running opt -std-compile-opts on it results in
a correctly working program (compiling at -O1 or higher
results in the test failing due to a problem with how we
output eh info into the IR).

uses the unwinding code that's built as part of your local

using the installed system unwinding code to get useful
results.)

f0c3354d99 When inlining through an 'nounwind' call, mark inlined 
calls 'nounwind'.  It is important for correct C++
exception handling that nounwind markings do not get
lost, so this transformation is actually needed for
correctness.

481dc721c3 The C++ exception handling personality function wants 
to know about calls that cannot throw ('nounwind'):
if such a call does throw for some reason then the
personality will terminate the program.  The distinction
between an ordinary call and a nounwind call is that
an ordinary call gets an entry in the exception table
but a nounwind call does not.  This patch sets up the
exception table appropriately.  One oddity is that
I've chosen to bracket nounwind calls with labels (like
invokes) - the other choice would have been to bracket
ordinary calls with labels.  While bracketing
ordinary calls is more natural (because bracketing
by labels would then correspond exactly to getting an
entry in the exception table), I didn't do it because
introducing labels impedes some optimizations and I'm
guessing that ordinary calls occur more often than
nounwind calls.  This fixes the gcc filter2 eh test,
at least at -O0 (the inliner needs some tweaking at
higher optimization levels).

ece2c04d53 Make instcombine promote inline asm calls to 'nounwind' 
calls.  Remove special casing of inline asm from the
inliner.  There is a potential problem: the verifier
rejects invokes of inline asm (not sure why).  If an
asm call is not marked "nounwind" in some .ll, and
instcombine is not run, but the inliner is run, then
an illegal module will be created.  This is bad but
I'm not sure what the best approach is.  I'm tempted
to remove the check in the verifier...

fe63fb986d Implement address space attribute for LLVM pointer types. Address spaces are 
regions of memory that have a target specific relationship, as described in the 
Embedded C Technical Report. 

This also implements the 2007-12-11-AddressSpaces test, 
which demonstrates how address space attributes can be used in LLVM IR.

In addition, this patch changes the bitcode signature for stores (in a backwards 
compatible manner), such that the pointer type, rather than the pointee type, is 
encoded. This permits type information in the pointer (e.g. address space) to be 
preserved for stores.

LangRef updates are forthcoming.

57d7d3f2d7 Move TargetData::hostIsLittleEndian out of line, which means we 
don't have to #include config.h in it.  #including config.h breaks
other projects that have their own autoconf stuff and try to #include
the llvm headers.  One obscure example is llvm-gcc.

bbc6597f02 Adding Ocaml bindings for the bitreader as requested by Sarah 
Thompson. Usage should be something like this:

open Llvm
open Llvm_bitreader

match read_bitcode_file fn with
  | Bitreader_failure msg ->
      prerr_endline msg
  | Bitreader_success m -> 
      ...;
      dispose_module m

Compile with: ocamlc llvm.cma llvm_bitreader.cma
              ocamlopt llvm.cmxa llvm_bitreader.cmxa

correctness issues and generalize the interface to the "operand folder".

ec90cd1bf8 Disable cfi directives for now, darwin does't support them. 
These should probably be something like:

  CFI(".cfi_def_cfa_offset 16\n")

where CFI is defined to a noop on darwin and other platforms
that don't support those directives.

1eff70451f Fix PR1836: in the interpreter, read and write apints 
using the minimum possible number of bytes.  For little
endian targets run on little endian machines, apints are
stored in memory from LSB to MSB as before.  For big endian
targets on big endian machines they are stored from MSB to
LSB which wasn't always the case before (if the target and
host endianness doesn't match values are stored according
to the host's endianness).  Doing this requires knowing the
endianness of the host, which is determined when configuring -
thanks go to Anton for this.  Only having access to little
endian machines I was unable to properly test the big endian
part, which is also the most complicated...

80a75bfae9 Adding a collector name attribute to Function in the IR. These 
methods are new to Function:

  bool hasCollector() const;
  const std::string &getCollector() const;
  void setCollector(const std::string &);
  void clearCollector();

The assembly representation is as such:

  define void @f() gc "shadow-stack" { ...

The implementation uses an on-the-side table to map Functions to 
collector names, such that there is no overhead. A StringPool is 
further used to unique collector names, which are extremely
likely to be unique per process.
