3432d1d1d5 Added a debugging code emitter that prints code to a file, debug to std::cerr,
and passes the real code to a memory-outputting code emitter. This may be
removed at a later point in development.

0d60345dcf Keep track of the current BasicBlock being processed so that a referencing
MachineInstr can later be patched up correctly.

b5b9adc5a0 Added 'r' or 'i' annotations to instructions, as SparcInstr.def has changed.
Non-obvious change: since I have changed ST and STD to be STF and STDF to
(a) closer resemble their name (NOT assembly text) in the Sparc manual, and
(b) clearly specify that they they are floating-point opcodes,
I made the same changes in this file.

91aee47a1b Added 'r' or 'i' annotations to instructions, as SparcInstr.def has changed.
Here I had to make one non-trivial change: add a function to get a version of
the opcode that takes an immediate, given an opcode that takes all registers.

This is required because sometimes it is not known at construction time which
opcode is used because opcodes are passed around between functions.

6ddd9d87a7 One of the first major changes to make the work of JITting easier: adding
annotations on instructions to specify which format they are (i.e., do they take
2 registers and 1 immediate or just 3 registers) as that changes their binary
representation and hence, code emission.

This makes instructions more like how X86 defines them to be. Now, writers of
instruction selection must choose the correct opcode based on what instruction
type they are building, which they already know. Thus, the JIT doesn't have to
do the same work by `discovering' which operands an instruction really has.

As this involves lots of small changes to a lot of files in lib/target/Sparc,
I'll commit them individually because otherwise the diffs will be unreadable.

cbfde0a612 * Now outputting a static function getBinaryCodeForInstr() (JIT-accessible)
* For debugging purposes:
  + output the predefined bit pattern of the instruction
* Fixed inefficiency: only load an operand from MachineInstr once
* Bug fix: did not advance bit index when seeing named bit-fields "annul", "cc"
  and "predict"
* Added a catch-all for non-supported instructions at the end of switch stmt.

the target-independent register allocators in the JIT.

of Sparc JIT (printing out instrs) on X86. Con: this increases linking time.

abb027cf41 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...

3de36f5309 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 .
