Add -o support for TableGen

I figure that misha has done a lot of things on my todo list, the least I
can do is reciprocate a bit.  :)

Store instructions are different from other Format 3.1/3.2 instructions in that
they prefer the destination register to be last. Thus, two new classes were made
for them that accomodate for having this layout of operands (F3_1rd, F3_2rd).

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6564 91177308-0d34-0410-b5e6-96231b3b80d8

* Fixed order of operands in classes 4.1 and 4.2; added 4.6 .

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6561 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.

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

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

Made a single common InvalidRegNum = -1.

Renamed a variable.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6472 91177308-0d34-0410-b5e6-96231b3b80d8

Support for annul/pred and other future flags on op codes.
Support for recording the physical register for implcit references.

Minor changes.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6470 91177308-0d34-0410-b5e6-96231b3b80d8

Added MachineCodeForInstruction object as an argument to
TmpInstruction constructors because every TmpInstruction object has
to be registered with a MachineCodeForInstruction to prevent leaks.
This simplifies the user's code.

Allow explicit physical registers for implicit operands.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6468 91177308-0d34-0410-b5e6-96231b3b80d8

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.

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.

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.

Reverting previous beautification changes.

Fixed rewriting of branches -- they now work forward and backward.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6463 91177308-0d34-0410-b5e6-96231b3b80d8

Removed useless code -- the byte order of output code is correct as is.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6462 91177308-0d34-0410-b5e6-96231b3b80d8

The 'rd' register is consistently mentioned last in instruction definitions.
Created new classes from which instructions inherit their ordering of fields.

* Put back into action SLL/SRL/SRA{r,i}6 instructions
* Fixed page numbers referring to the Sparc manual

3 more bugs from the SPEC codes and from richards_benchmark.c
