cd60313915 Renamed MachineCodeEmitter.cpp -> X86CodeEmitter.cpp as it conflicts with the
target-independent lib/CodeGen/MachineCodeEmitter.cpp; preserved CVS history.

906f5fa5c8 * Removed SparcEmitter.cpp; rolled into lib/Target/Sparc/SparcV9CodeEmitter.cpp
* No more createX86Emitter() vs. createSparcEmitter() -- there can be only one
* As a result, the memory management semantics must be handled according to
  platform -- the parameters to mmap() are particularly sensitive to the host
  architecture.

24a26e58ef The flag modifications weren't picking up the old values of the
flags before. Save them in a temporary variable, then restore them from the
temporary after creating the new constant.

f3d3ca18b5 Added MachineCodeForInstruction object as an argument to

to be registered with a MachineCodeForInstruction to prevent leaks.

7952d6088e Changes to allow explicit physical register arguments that have been
preallocated.  While reg-to-reg dependences were already handled, this
change required new code for adding edges to/from call instructions.
This was part of the extensive changes to the way code generation occurs
for function call arguments and return values.
See log for CodeGen/PhyRegAlloc.cpp.

9635867d6f Several bug fixes: globals in call operands were not being pulled out;
globals in some other places may not have been pulled out either;
globals in phi operands were being put just before the phi instead of
in the predecessor basic blocks.

d0d06ad4f3 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.

9b03633265 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.

3f7b58bca0 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.

8996f44f7a Fixed ordering of elements in instructions: although the binary instructions
list (rd, rs1, imm), in that order (bit-wise), the actual assembly syntax is
instr rd, imm, rs1, and that is how they are constructed in the instruction
selector. This fixes the discrepancy.

Also fixed some comments along the same lines and fixed page numbers referring
to where instructions are described in the Sparc manual.

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.

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

Makefile).

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

2c821cc06e 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.

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

e941291a7a 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.

186a1f71e6 Changes to the V2 bytecode format:
- Null values are implicitly encoded instead of explicitly, this makes
    things more compact!
  - More compactly represent ConstantPointerRefs
  - Bytecode files are represented as:
      Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab
    instead of
      Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab
    which makes a lot of things simpler.

Writer changes:
  - We now explictly encode versioning information in the bytecode files.
  - This allows new code to read bytecode files produced by old code, but
    new bytecode files can have enhancements such as the above.  Although this
    makes the reader a bit more complex (having to deal with old formats), the
    writer only needs to be able to produce the most recent version.

- Fix problems where the constant table would not get updated when
    resolving constants causes other constants to change.

    things more compact!
  - More compactly represent ConstantPointerRefs
  - Bytecode files are represented as:

Changes to the reader:
  - Function loading code is much simpler.  We now no longer make function
    PlaceHolderHelper objects to be replaced with real functions.

0252e49f6d Convert LICM over to use AliasSetTracker. Besides being nicer, this automatically
allows LICM to use access sizes to help alias analysis be more precise.
