ab3b2ea95c * Allow passing in an unsigned configuration to allocateSparcTargetMachine() 
a default value is set in the header file.
* Fixed some code layout to make it more consistent with the rest of codebase
* Added addPassesToJITCompile() with relevant passes

30ca3282a1 Moved generation of the SparcV9CodeEmitter.inc file higher in the Makefile so 
that Makefile.common would see it.

0d507cb055 Add prototypes to add passes to JIT compilation and code emission. 
Also, added annotations to how instructions are modified (reg/imm operands).
Added prototype for adding register numbers to values pass for interfacing with
the target-independent register allocators in the JIT.

125a99a9a3 Broke out class definition from SparcV9CodeEmitter, and added ability to take a 
MachineCodeEmitter to make a pass-through debugger -- output to memory and to
std::cerr.

4931c59635 Link in Sparc libs for the JIT, even on X86 to be able to support debugging 
of Sparc JIT (printing out instrs) on X86. Con: this increases linking time.

afffd58fe6 Allow for specification of which JIT to run on the commandline. 
`lli -march=x86' or `lli -march=sparc' will forcefully select the JIT even on a
different platform. Running lli without the -march option will select the JIT
for the platform that it's currently running on.

Pro: can test Sparc JIT (debug printing mode) on X86 -- faster to compile/link
LLVM source base to test changes.
Con: Linking lli on x86 now pulls in all the Sparc libs -> longer link time
(but X86 can bear it, right?)

In the future, perhaps this should be a ./configure option to enable/disable
target JITting...

e315a4f211 SparcV9CodeEmitter.cpp is a part of the Sparc code emitter. The main function 
that assembles instructions is generated via TableGen (and hence must be built
before building this directory, but that's already the case in the top-level
Makefile).

Also added is .cvsignore to ignore the generated file `SparcV9CodeEmitter.inc',
which is included by SparcV9CodeEmitter.cpp .

but there was already a constant of the new type created.  Before, these types
were never merged together, now they are.

91c5d68261 Minor cleanups. 
This hunk:
-    } else if (Src->getNumOperands() == 2 && Src->use_size() == 1) {
+    } else if (Src->getNumOperands() == 2) {

Allows GEP folding to be more aggressive, which reduces the number of instructions
and can dramatically speed up BasicAA in some cases.

  .mem2reg suffixes.  This produces what people think of as SSA.

127a46eeba Fixed compilation errors, command-line argument declarations, cleaned up code to 
look nicer and removed useless stuff.

Also renamed a few variables, moved them into namespaces, converted outputting
to a file into a print to std::cerr with a DEBUG() guard, as all passes should
do anyway.

No functional changes have been made. However, this code now compiles.

1db4cefc28 Made the code readable: 
* Lines must be wrapped at 80 chars. This is a hard limit.
* Consistent style on functions, braces, if, for, etc. Code must be readable.

No functional changes have been made, even though I added a new typedef.

731913bab3 Initial checkin of PRE on LLVM. This implementation is still lacking in 
several ways:

 * Load expressions are not PRE'd well.  Alias Analysis should be used to
   get accurate information when computing anticipatibility.
 * The expression collection implementation does not handle PHI nodes properly,
   thus the implementation misses many opportunities to PRE.
 * This code could be sped up quite a bit

Despite these flaws, the code seems to work well, and handles PR's as one
would expect.
