No new testcases. However, this patch makes all supported JIT testcases in 
test/ExecutionEngine  pass on Sparc.

llvm-svn: 192176

[Sparc] Do not hardcode nop in the delay slot of TLS_CALL. Use DelaySlotFiller to fill the delay slot instead.

addx/subx does not modify conditional codes whereas addxcc/subxx does.

llvm-svn: 192053

llvm-svn: 191180

[Sparc] Make SPARC instructions' encoding well defined such that TableGen can automatically generate code emitter.

llvm-svn: 191168

[Sparc] Clean up MOVcc instructions so that TableGen can encode them correctly. No functionality change intended.

llvm-svn: 191167

[Sparc] Clean up branch instructions, so that TableGen can encode branch conditions as well. No functionality change intended.

[Sparc] Use HWEncoding instead of unused Num field in Sparc register definitions. Also, correct the definitions of RETL and RET instructions.

       using two instructions (sethi and store).

Also clean up the arguments to all the MOVCC instructions so the
operands always are (true-val, false-val, cond-code).

Don't ignore the high 32 bits of the immediate.

This fixes the pic32 code model for SPARC v9.

llvm-svn: 179469

This requires v9 cmov instructions using the %xcc flags instead of the
%icc flags.

Still missing:
- Select floats on %xcc flags.
- Select i64 on %fcc flags.

llvm-svn: 178737

The same compare instruction is used for 32-bit and 64-bit compares. It
sets two different sets of flags: icc and xcc.

This patch adds a conditional branch instruction using the xcc flags for
64-bit compares.

llvm-svn: 178621

SPARC v9 defines new 64-bit shift instructions. The 32-bit shift right
instructions are still usable as zero and sign extensions.

This adds new F3_Sr and F3_Si instruction formats that probably should
be used for the 32-bit shifts as well. They don't really encode an
simm13 field.

llvm-svn: 178525

The 'sparc' architecture produces 32-bit code while 'sparcv9' produces
64-bit code.

It is also possible to run 32-bit code using SPARC v9 instructions with:

  llc -march=sparc -mattr=+v9

llvm-svn: 178524

We are going to use the same registers for 32-bit and 64-bit values, but
in two different register classes. The I64Regs register class has a
larger spill size and alignment.

The addition of an i64 register class confuses TableGen's type
inference, so it is necessary to clarify the type of some immediates and
the G0 register.

In 64-bit mode, pointers are i64 and should use the I64Regs register
class. Implement getPointerRegClass() to dynamically provide the pointer
register class depending on the subtarget. Use ptr_rc and iPTR for
memory operands.

Finally, add the i64 type to the IntRegs register class. This register
class is not used to hold i64 values, I64Regs is for that. The type is
required to appease TableGen's type checking in output patterns like this:

  def : Pat<(add i64:$a, i64:$b), (ADDrr $a, $b)>;

SPARC v9 uses the same ADDrr instruction for i32 and i64 additions, and
TableGen doesn't know to check the type of register sub-classes.

llvm-svn: 178522

The types of register variables no longer need to be specified in output
patterns.

llvm-svn: 177845

Also update the documentation since Sparc is the nicest backend, and
used as an example in WritingAnLLVMBackend.

llvm-svn: 177835

The SelectionDAG graph has MVT type labels, not register classes, so
this makes it clearer what is happening.

This notation is also robust against adding more types to the IntRegs
register class.

 Rename FLUSH to FLUSHW.
