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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6528 91177308-0d34-0410-b5e6-96231b3b80d8

* 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.

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.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6471 91177308-0d34-0410-b5e6-96231b3b80d8

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.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6469 91177308-0d34-0410-b5e6-96231b3b80d8

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.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6467 91177308-0d34-0410-b5e6-96231b3b80d8

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.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6466 91177308-0d34-0410-b5e6-96231b3b80d8

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.

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.

Okay totally give up on trying to optimize aggregates that cannot be completely
broken up into their elements.  Too many programs break because of this.

Made the register and immediate versions of instructions consecutive.

add a check that allows the SRoA pass to avoid breaking programs, even if their
behavior is technically undefined

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6438 91177308-0d34-0410-b5e6-96231b3b80d8

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.

Sorry, correcting small typo.

Added configurable options for the Linker and Archiver.

Added the CloneTrace function which clones traces. It takes a vector of basic blocks, removes
internal phi nodes, and returns a new vector of basic blocks.

Added support for cloning a trace.

Makefile: Make SparcV9CodeEmitter.inc depend on SparcV9_F*.td as well.
SparcV9_F3.td: F3_12 and F3_13 instructions have rd and rs1 fields. Also,
 their fields were totally screwed up. This seems to fix the problem.
