the TableGen descriptions; all unset bits are thus errors.
* As a result, found and fixed instructions where some operands were not
actually assigned into the right portion of the instruction.

area to avoid using up precious stack space within the 4095 offset limit
from %fp. Such objects that would themselves live at a large offset
were being put there already so this is a simple change.

deletes it, but we were merrily trying to fix the operands of that
instruction anyway! Instead, fix the replacement instruction.
(2) An Improvement: Check for and extract global values in all operands,
not just in known pointer operands. For example, they can occur in
call arguments, and probably other unforeseeable places as well.
This also eliminates the special-case handling of Load and Store.

(1) select: Ok to convert a pointer to a float or double.
(2) regalloc: Some MachineInstr* for caller-saving code before a call
were being inserted before and after the call!
(3) Don't insert the caller-saving instructions in the
MachineCodeForInstruction for the Call instruction.
*All* instructions generated by register allocation need to be
recorded in those maps, but it needs to be done uniformly.

SingleSource except oopack and Oscar. (Sorry, Oscar.)
include/llvm/Target/TargetInstrInfo.h: Remove virtual print method. Add
accessors for ImplicitUses/Defs.
lib/Target/TargetInstrInfo.cpp: Remove virtual print method. If you
really wanted this, just use MI->print(O, TM); instead...
lib/Target/X86:
FloatingPoint.cpp: ...like this.
X86InstrInfo.h: Remove virtual print method. Define the PrintImplUses
target-specific flag bit.
X86InstrInfo.def: Add the PrintImplUses flag to all the instructions
which implicitly use CL, because the assembler needs to see the CL in
order to generate the right instruction.
Printer.cpp: Ditch fnIndex at Chris's request. Now we use CurrentFnName
to name constants in the constant pool for each function instead. This
avoids keeping state between runOnMachineFunction() invocations, which
is a no-no. Having MangledGlobals be global is a bogon I'd like to get
rid of too, but making it a static member of Printer causes link errors
(why???).
Make NumberForBB into a member of Printer instead of a global, too.
Make printOp and printMemReference into methods of Printer.
X86InstrInfo::print is now Printer::printMachineInstruction, because
TargetInstrInfo::print is history. (Because of this, we have to qualify
the names of some TargetInstrInfo methods we call.)
Print out the ImplicitUses field of any instruction we print that has
the PrintImplUses bit set.

involves removing the [bwl] suffixes from instruction names, as well
as some other distinguishing marks (32/64/80 on fp insns, _i suffixes, etc.)
Lowercase all instr. names as well for consistency's sake.

to print various things on a module-by-module basis (currently, only the
former is used).
Don't print < > around names. The assembler can't take it.
Print pseudoinstructions only as comments. The poor little assembler can't
take that, either.
llvm-svn: 6789
Move LowerAllocations, PrintFunction, and SymbolStripping passes, and
the corresponding -disable-strip and -d options, over here to the SPARC
target-specific bits of llc. Rename -d to -dump-asm.
tools/llc/Makefile:
Reindent. Add x86 library so that llc compiles again.
tools/llc/llc.cpp:
Remove support for running arbitrary optimization passes. Use opt instead.
Remove LowerAllocations, PrintFunction, and SymbolStripping passes, as noted
above.
Allow user to select a backend (x86 or SPARC); default to guessing from
the endianness/pointer size of the input bytecode file.
Fix typos.
Delete empty .s file and exit with error status if target does not support
static compilation.

* BPA and BPN do not take a %cc register as a parameter
* SLL/SRL/SRA{r,i}5 are there for a reason - they are ONLY 32-bit instructions
* Likewise, SLL/SRL/SRAX{r,i}6 are only 64-bit
* Added WRCCR{r,i} opcodes
llvm-svn: 6655
* Removed instruction scheduling as it is too slow to run in a JIT environment
* Removed other passes because they aren't necessary and can slow JIT down
