SelectionDAGISel can now natively handle Switch instructions, in the same
...
manner that the LowerSwitch LLVM to LLVM pass does: emitting a binary
search tree of basic blocks. The new approach has several advantages:
it is faster, it generates significantly smaller code in many cases, and
it paves the way for implementing dense switch tables as a jump table by
handling switches directly in the instruction selector.
This functionality is currently only enabled on x86, but should be safe for
every target. In anticipation of making it the default, the cfg is now
properly updated in the x86, ppc, and sparc select lowering code.

implementation of a Target{RegInfo, InstrInfo, Machine, etc} now has a separate
header and a separate implementation file.

only recompile a few files.
Note that SparcInternals.h is still around; its contents should be minimized.

PreSelection is not optional, it performs a necessary and vital transformation
...
for the Sparc backend: breaking up constant expressions. Thus, we cannot have it
guarded by a conditional, it should never be disabled.
Also, it's now available for the JIT since it is a FunctionPass.

yet utilize the delay slots effectively, so it is not necessary to make an
overly complicated algorithm for something that's not used.

Several important bug fixes:
...
(1) Cannot use ANDN(ot), ORN, and XORN for boolean ops, only bitwise ops.
(2) Conditional move instructions must distinguish signed and unsigned
condition codes, e.g., MOVLE vs. MOVLEU.
(3) Conditional-move-on-register was using the cond-move-on-cc opcodes,
which produces a valid-looking instruction with bogus registers!
(4) Here's a really cute one: dividing-by-2^k for negative numbers needs to
add 2^k-1 before shifting, not add 1 after shifting. Sadly, these
are the same when k=0 so our poor test case worked fine.
(5) Casting between signed and unsigned values was not correct:
completely reimplemented.
(6) Zero-extension on unsigned values was bogus: I was only doing the
SRL and not the SLLX before it. Don't know WHAT I was thinking!
(7) And the most important class of changes: Sign-extensions on signed values.
Signed values are not sign-extended after ordinary operations,
so they must be sign-extended before the following cases:
-- passing to an external or unknown function
-- returning from a function
-- using as operand 2 of DIV or REM
-- using as either operand of condition-code setting operation
(currently only SUBCC), with smaller than 32-bit operands
Also, a couple of improvements:
(1) Fold cast-to-bool into Not(bool). Need to do this for And, Or, XOR also.
(2) Convert SetCC-Const into a conditional-move-on-register (case 41)
if the constant is 0. This was only being done for branch-on-SetCC-Const
when the branch is folded with the SetCC-Const.

Several fixes to handling of int CC register:
...
(1) An int CC live range must be spilled if there are any interferences,
even if no other "neighbour" in the interf. graph has been allocated
that reg. yet. This is actually true of any class with only one reg!
(2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must
be spilled so that the machine-independent spill code doesn't have to
make the machine-dependent decision of which CC name to use based on
operand type: %xcc or %icc. (These are two halves of the same register.)
(3) LR->isMarkedForSpill() is no longer the same as LR->hasColor().
These should never have been the same, and this is necessary now for #2 .
(4) All RDCCR and WRCCR instructions are directly generated with the
phony number for %ccr so that EmitAssembly/EmitBinary doesn't have to
deal with this.

Apparently, the "regType" and "regClass" used in the Sparc backend are not both

Update file comment to contain a bunch of the overview mapping-info
documentation previously buried within the file.
Remove some unnecessary include/using stmts.
Rename pass to MappingInfoCollector.
Rewrite a lot of it so it doesn't use global instance variables and so
it outputs into MappingInfo objects and then dumps those out, instead of going
straight to an assembly file.
Change name of factory to getMappingInfoCollector.
Fold prologue & epilogue writers into MappingInfo methods.

* 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.

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.

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.

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.

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.

Several major fixes, particularly in emitting constant aggregates:
...
(1) Padding bytes between structure fields (for alignment) were never
being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
were never handled.
(3) Support new model for external/uninitialized/initialized globals.
Uninitialized globals are no longer emitted since they are external.
Initialized globals may go either in .bss or in .data.

Significant changes to correctly spill CC registers and to correctly
...
handle conditional move instructions:
-- cpMem<->Reg functions now support CC registers (int and FP) correctly.
Also, cpMem<->Reg functions now return a vector of machine instructions.
-- Scratch registers must be explicitly provided to cpMem<->Reg when
needed, since CC regs need one to be copied to/from memory.
-- CC regs are saved to a scratch register instead of stack.
-- All regs used by a instruction are now recorded in MachineInstr::regsUsed,
since regs used to save values *across* an instruction are not obvious
either from the operands or from the LiveVar sets.
-- An (explicit or implicit) operand may now be both a def and a use.
This is needed for conditional move operations.
So an operand may need spill code both before and after the instruction.
Other changes:
-- Added several get{Class,Type} functions.
-- Added unified-to-local register number conversion.
-- class MachineCodeForBasicBlock is now an annotation on BasicBlock.
-- Suggest/Color methods may modify the MachineInstr (and always did),
so don't make that argument const!
-- Caller-saving code doesn't need its special purpose code for
handling CC registers since cpMem<->Reg handle those correctly now.

-- correct sign extensions for integer casts and for shift-by-constant
instructions generated for integer multiply
-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect stack frame size when padding a section
-- folding getelementptr operations with mixed array and struct indexes
-- use uint64_t instead of uint for constant offsets in mem operands
-- incorrect coloring for CC registers (both int and FP): interferences
were being completely ignored for int CC and were considered but no
spills were marked for fp CC!
Also some code improvements:
-- better interface to generating machine instr for common cases
(many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
one codegen phase to another (now used to pass information about
CALL/JMPLCALL operands from selection to register allocation)
-- all sizes and offests in class TargetData are uint64_t instead of uint

(1) Avoid hard-coding some register numbers.
(2) Fix some incorrect branch opcodes.
(3) Don't try to move int register to float register!
(4) If an operand being forwarded is a constant and it doesn't fit
into the immed field of the copy machine instruction, then
generate a load-constant instead of a copy.
(5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2".
