7e060be881 The functions to create new instances of passes are no longer methods in the
UltraSparc class. Comments are also doxygen-compatible now.

e9414cab00 Fix problems linking against the reoptimizer; _llvm_regAllocState must have
externally-visible linkage, and SaveStateToModule must default to true for llc.
I don't remember why I made it const; perhaps it should be deconstified.

213904133d Operand numbers are now ints. Save the register allocation of the value
each instruction produces as "operand" -1, and the other operands as 0
.. n, as before. PhyRegAlloc::saveState() is refactored into
PhyRegAlloc::saveStateForValue().

351881793a 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.

f905ed5204 Switch to using the standard representation of the constant pool -- namely, the
MachineConstantPool. This involved refactoring the two classes involved in
printing out Sparc assembly. In fact, they should share all this code anyway.

feed25ffdc * Stop making a global for each constant that cannot live in an instruction;
it will be converted to a MachineConstantPool index during instruction
  selection
* This is now eligible to become a FunctionPass since it does not have any side
  effects outside of the function it is processing.

e668dab5b3 Change all machine basic block modifier functions in MRegisterInfo to
return the number of instructions added to/removed from the basic block
passed as their first argument.

Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.

dac9131e28 Preselection is _not_ a basicblock pass, because it adds global variables to
the module.  This change converts it from being a basic block pass to being
a simple pass.  This allows elimination of the annotation and simplification
of the logic for moving constants into global variables.

43a5ff8d40 Emit x86 instructions for: A = B op C, where A and B are 16-bit registers,
C is a constant which can be sign-extended from 8 bits without value loss,
and op is one of: add, sub, imul, and, or, xor.

This allows the JIT to emit the one byte version of the constant instead of
the two or 4 byte version.  Because these instructions are very common, this
can save a LOT of code space.  For example, I sampled two benchmarks, 176.gcc
and 254.gap.

BM        Old     New    Reduction
176.gcc 2673621 2548962  4.89%
254.gap  498261  475104  4.87%

Note that while the percentage is not spectacular, this did eliminate
124.6 _KILOBYTES_ of codespace from gcc.  Not bad.

Note that this doesn't effect the llc version at all, because the assembler
already does this optimization.

5ef6ffd6c3 * Spell "necessary" correctly
* Print floating point values using C99 hexadecimal style FP if possible.
  This increases the number of floating point constants that may be emitted
  inline, and improves precision for global variable initializers which
  can not be emitted in integer form.

This fixes the Olden/Power benchmark with the CBE!!!!

9860e77110 * Be TBAA safe
* Fix isFPCSafeToPrint to find more constants safe to print, which it was
  failing because ftostr was padding with leading space characters.
* Scan the entire module for global constants instead of each function at a
  time.  This has the advantage of allowing us to emit constants at global
  scope instead of function scope.  This speeds FP programs quite a bit.

dd76acac3f A couple of minor code cleanups.
Print literal doubles using ftostr instead of <<, because it yields higher precision numbers.

but forgot to mention it.)

4efe342424 Convert PhyRegAlloc into a proper pass.
PhyRegAlloc.cpp:
 Don't include TargetMachine.h or TargetRegInfo.h, because these are provided
  by PhyRegAlloc.h.
 Merge class RegisterAllocator into class PhyRegAlloc.
 Simplify & move ctor, dtor to PhyRegAlloc.h.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 MarkAllocatedRegs() becomes a member method, with fewer args.

PhyRegAlloc.h:
 Include Pass.h, TargetMachine.h and TargetRegInfo.h. Don't declare
  TargetRegInfo forward.
 Give AddedInstrns the obvious clear() method.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 Add prototype for markAllocatedRegs().
 Remove unused inline void constructLiveRanges().
