4c080863de Remove TwoAddressInstruction from the public headers and add an ID
instead, since this pass doesn't expose any state to its users.

71499ded4d Add TwoAddressInstructionPass to handle instructions that have two or
more operands and the two first operands are constrained to be the
same. The pass takes an instruction of the form:

        a = b op c

and transforms it into:

        a = b
        a = a op c

and also preserves live variables.

43f692f90f When a variable is killed and redifined in a basic block only one
killing instruction is tracked. This causes the LiveIntervals to
create bogus intervals. The workaound is to add a range to the
interval from the redefinition to the end of the basic block.

2cffeec014 Add a new AliassetTracker::remove method. Because we need to be able to remove
a pointer from an AliasSet, maintain the pointer values on a doubly linked
list instead of a singly linked list, to permit efficient removal from the
middle of the list.

d71295a684 Reorganized the Sparc backend to be more modular -- each different
implementation of a Target{RegInfo, InstrInfo, Machine, etc} now has a separate
header and a separate implementation file.

This means that instead of a massive SparcInternals.h that forces a
recompilation of the whole target whenever a minor detail is changed, you should
only recompile a few files.

Note that SparcInternals.h is still around; its contents should be minimized.

4d7af65903 Change interface of MachineOperand as follows:
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
    b) add isUse(), isDef()
    c) rename opHiBits32() to isHiBits32(),
              opLoBits32() to isLoBits32(),
              opHiBits64() to isHiBits64(),
              opLoBits64() to isLoBits64().

This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.

This is kind of invasive, because they prepend the long filename to the archive
member data, and then lie about the size. So we have to keep track of the real
size.

01b2d61311 Fixed the CBE on Solaris/Sparc. We need to define the return value of
the write() system call because it returns 64 bits on Solaris 64 bit,
and an implicit return value of int says it returns 32 bits.
Admittedly, this is a bit of a hack.

7152da38ef Cleanup and restructure the code to make it easier to read and maintain.
The only functionality change is that we now implement:
  Regression/Transforms/TailCallElim/intervening-inst.ll

Which is really kinda pointless, because it means that trivially dead code
does not interfere with -tce, but trivially dead code probably wouldn't be
around anytime when this pass is run anyway.

The point of including this change it to support other more aggressive
transformations when we have the analysis capabilities to do so.

8d1dbd2134 Emit & read more compressed bytecode by not emitting a bytecodeblock for
each basic block in function.  Instead, just emit a stream of instructions,
chopping up basic blocks based on when we find terminator instructions.  This
saves a fairly substantial chunk of bytecode space.  In stripped, sample
cases, for example, we get this reduction in size:

197.parser: 163036 -> 137180:  18.8% reduction
254.gap   : 844936 -> 689392:  22.6%
255.vortex: 621724 -> 528444:  17.7%

...

Not bad for something this simple.  :)  Note that this doesn't require a new
bytecode version number at all, though version 1.1 should not need to support
the old format.

9b527704f7 Add an option to enable the SSA based peephole optimizer.
Eventually this pass will provide substantially better code in the interim between when we
have a crappy isel and nice isel.  Unfortunately doing so requires fixing the backend to
actually SUPPORT all of the fancy addressing modes that we now generate, and writing a DCE
pass for machine code.  Each of these is a fairly substantial job, so this will remain disabled
for the immediate future.  :(

accesses, since it must make 2 aligned accesses for each unaligned one.

This change speeds up type resolution by checking to see if a type is
  recursive, and if it's not, using a more efficient algorithm.

  kc++ --version to 17s from 33s

* Major efficiency improvement: In BytecodeParser::insertValue, do not allocate
  a new ValueTab entry just because some value exists with a large type.  This
  dramatically reduces the number of allocations/deallocations performed by the
  bytecode reader, and speeds up parsing of Kimwitu++ from 34s to 17s.  This is
  to help address PR127

c59c118e44 ISO 9899 7.13.2.1 (3) says that "[...] the values of objects of automatic
storage duration that are local to the function containing the invocation of the
[...] setjmp macro that do not have volatile-qualified type and have been
changed between the setjmp invocation and longjmp call are indeterminate."

As such, we have to mark all variables in a function that uses 'invoke' as
volatile.

This fixes PR77

f905ed5204 Switch to using the standard representation of the constant pool -- namely, the
MachineConstantPool. This involved refactoring the two classes involved in
printing out Sparc assembly. In fact, they should share all this code anyway.

feed25ffdc * Stop making a global for each constant that cannot live in an instruction;
it will be converted to a MachineConstantPool index during instruction
  selection
* This is now eligible to become a FunctionPass since it does not have any side
  effects outside of the function it is processing.

49ab7f2089 * Use the MachineConstantPool for storing constants instead of a hash_set;
* Do not create new globals for constants!

Also, order #includes as per coding style guide

af955ba503 Refactor the return-from-function code into popStackAndReturnValueToCaller().
Make external function calls slightly less special; now they get a stack frame.
