* 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.

* Institute a hack for the Sparc call to mmap() to get our generated code to be
  laid out closer to the VM so that calls to library functions (e.g. puts()) and
  callback (e.g.  JITResolver::CompilationCallback) fit into 30 bits of the call
  instruction.
* Abort if architecture is not yet supported (not X86 or Sparc) because it
  likely requires a different set of parameters to mmap() .
* Stop using hard-coded values for page size; use sysconf(_SC_PAGESIZE) instead.

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.

* Gave the file a maintainer.
* Cleaned up the layout somewhat.

Stop ignoring the `cc' field, we actually use it now (e.g. conditional move)

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6555 91177308-0d34-0410-b5e6-96231b3b80d8

Moved FInfo.cpp to lib/Target/Sparc as it is Sparc-specific.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6554 91177308-0d34-0410-b5e6-96231b3b80d8

Minor cleanups.
This pass should be moved to lib/Target/Sparc since it's sparc specific
It also needs a file comment.

Remove usage of noncopyable classes to clean up doxygen output.

In particular these classes are the last that link the noncopyable classes
with the hash_map, vector, and list classes.

Added MOVR (move int reg on register condition), aka comparison with zero.
None of these instructions are actually used in the Sparc backend, so no changes
were required in the instruction selector.

SparcInstr.def: added 'r' and 'i' versions of MOV(F)cc instructions

SparcInstrSelection.cpp:
* Fixed opcodes to return correct 'i' version since the two functions are each
  only used in one place.
* Changed name of function to have an 'i' in the name to signify that they each
  return an immediate form of the opcode.
* Added a warning if either of the functions is ever used in a context which
  requires a register-version opcode.

SparcV9_F4.td: fixed class F4_3, added F4_4 and notes that F4_{1,2} need fixing
SparcV9.td: added the MOV(F)cc instructions

Merged in tools/lli/JIT/SparcEmitter.cpp, coupled with the JITResolver taken
from lib/Target/X86/X86CodeEmitter.cpp .

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

* 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.
