Nice tasty llc fixes. These should fix LLC for x86 for everything in
...
SingleSource except oopack and Oscar. (Sorry, Oscar.)
include/llvm/Target/TargetInstrInfo.h: Remove virtual print method. Add
accessors for ImplicitUses/Defs.
lib/Target/TargetInstrInfo.cpp: Remove virtual print method. If you
really wanted this, just use MI->print(O, TM); instead...
lib/Target/X86:
FloatingPoint.cpp: ...like this.
X86InstrInfo.h: Remove virtual print method. Define the PrintImplUses
target-specific flag bit.
X86InstrInfo.def: Add the PrintImplUses flag to all the instructions
which implicitly use CL, because the assembler needs to see the CL in
order to generate the right instruction.
Printer.cpp: Ditch fnIndex at Chris's request. Now we use CurrentFnName
to name constants in the constant pool for each function instead. This
avoids keeping state between runOnMachineFunction() invocations, which
is a no-no. Having MangledGlobals be global is a bogon I'd like to get
rid of too, but making it a static member of Printer causes link errors
(why???).
Make NumberForBB into a member of Printer instead of a global, too.
Make printOp and printMemReference into methods of Printer.
X86InstrInfo::print is now Printer::printMachineInstruction, because
TargetInstrInfo::print is history. (Because of this, we have to qualify
the names of some TargetInstrInfo methods we call.)
Print out the ImplicitUses field of any instruction we print that has
the PrintImplUses bit set.

Fairly major change: emit fixed sized allocas in the entry block as a variable,
...
instead of a variable pointer and an alloca. All accesses to the variable then
use the address-of operator to access it. This plays better with the internal
GCC code generation phases, which bail early on functions which contain allocas.
It also makes the code a bit easier to read.

...
The JIT is designed to code-generate a function at-a-time. That means that any
pass can only make local changes to its function. Period.
Because the Sparc PreSelection pass claims to be a BasicBlock pass while adding
globals to the Module, it cannot be run with the other passes, because by this
time, the globals have been output already by the JIT, and the addresses of any
globals appearing AFTER this point are not recognized.
However, the PreSelection pass is a requirement for correctness in the Sparc
codegen path, so it MUST be run.

* Instead of re-inventing the MachineConstantPool emitter that's already given
...
in Emitter.cpp, just convert the Sparc version of the constant pool into
what's already supported and inter-operate.
* Implemented a first pass at lazy function resolution in the JITResolver. That
required adding a SparcV9CodeEmitter pointer to simplify generating
bit-patterns of the instructions.
* SparcV9CodeEmitter now creates and destroys static TheJITResolver, which makes
sense because the SparcV9CodeEmitter is the only user of TheJITResolver, and
lives for the entire duration of the JIT (via PassManager which lives in VM).
* Changed all return values in the JITResolver to uint64_t because of the 64-bit
Sparc architecture.
* Added a new version of getting the value of a GlobalValue in the
SparcV9CodeEmitter, which now works for already-generated functions (JITted or
library functions).
* Removed little-used and unused functions, cleaning up the internal view of the
SparcV9CodeEmitter.

instruction.

I have finally seen the light. The code to change the opcode must live higher in
...
the loop, and in both cases. In the first case, it is a VReg that is a constant
so it may be actually converted to a constant. In the second case, it is already
a constant, but then if it doesn't change its type (e.g. to become a register
and have the value loaded from memory if it is too large to live in its
instruction field), we must change the opcode BEFORE the 'continue', otherwise
we miss the opportunity.

Changes to allow explicit physical register arguments that have been

Extensive changes to the way code generation occurs for function
...
call arguments and return values:
Now all copy operations before and after a call are generated during
selection instead of during register allocation.
The values are copied to virtual registers (or to the stack), but
in the former case these operands are marked with the correct physical
registers according to the calling convention.
Although this complicates scheduling and does not work well with
live range analysis, it simplifies the machine-dependent part of
register allocation.

Because the format of the shift instructions is `shift r, shcnt, r', the
...
instructions of format 3.12 and 3.13 cannot inherit from F3rdrs1, because that
implies that the two registers are the first two parameters to the instruction.
Thus I made the instructions inherit from F3rd again, and manually added an rs1
field AFTER the shcnt field in the instruction, which maps to the appropriate
place in the instruction.
The other changes are just elimination of unnecessary spaces.

When TableGen finds an error in the SparcV9.td file, it exits with a non-zero
...
exit code. This, in turn, makes an empty file SparcV9CodeEmitter.inc, and only
much later, produces a link error because the key function that TableGen creates
isn't found.
Using a temporary file in the middle forces a good .INC file to be generated by
TableGen, and it will keep trying until you fix the input file.

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.

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.

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.

56d27325c0
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...

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 .
