e5d4f11e14 Fixed a segfault in gccld. 
The original code does not work because the value from WorkList.end() is
invalidated once WorkList.erase() is called.  To ensure proper functionality,
we must ensure that WorkList.erase() is always called before WorkList.end().

ea0aa3f793 Use the registers g1 and g5 as temporaries for making far jumps and far calls, 
because saving i1 and i2 to their ``designated'' stack slots corrupts unknown
memory in other functions, standard libraries, and worse.

In addition, this has the benefit of improving JIT performance because we
eliminate writing out 4 instructions in CompilationCallback() and 2 loads and 2
stores.

33b0d331f0 1. Bug fix: was using SLL instead of SLLX for ULongTy. Chump. 
2. Handle fp-to-uint conversions directly here instead of relying on
   a pre-transformation to replace them with the 2-step conversion.
3. Use size rather than explicitly checking types when deciding what
   opcodes to use, wherever possible.  This is less error prone (the
   bug fix above was not the first time!).
4. Float-to-pointer casts shd now work though this hasn't been tested.

2f831da9af SparcV9CodeEmitter.cpp: 
* Doxygen-ified comments
* Added capability to make far calls (i.e., beyond 30 bits in CALL instr)
  which implies that we need to delete function references that were added by
  the call to addFunctionReference() because the actual call instruction is 10
  instructions away (thanks to 64-bit address construction)
* Cleaned up code that generates far jumps by using an array+loop

SparcV9CodeEmitter.h:
* Explained more of the side-effects of emitFarCall()

48144de834 (1) Major fix to the way unused regs. are marked and found for the FP 
Single and FP double reg types (which share the same reg class).
    Now all methods marking/finding unused regs consider the regType
    within the reg class, and SparcFloatRegClass specializes this code.
(2) Remove machine-specific regalloc. methods that are no longer needed.
    In particular, arguments and return value from a call do not need
    machine-specific code for allocation.
(3) Rename TargetRegInfo::getRegType variants to avoid unintentional
    overloading when an include file is omitted.

        %tmp.5 = cast short %tmp.3 to int               ; <int> [#uses=1]
        %tmp.7 = shl int %tmp.5, ubyte 8                ; <int> [#uses=1]
        %tmp.8 = cast int %tmp.7 to short               ; <short> [#uses=1]
        ret short %tmp.8
}

before, now it becomes:
short %kernel(short %t1.1) {
        %tmp.3 = shr short %t1.1, ubyte 8               ; <short> [#uses=1]
        %tmp.8 = shl short %tmp.3, ubyte 8              ; <short> [#uses=1]
        ret short %tmp.8
}

which will become:
short %kernel(short %t1.1) {
        %tmp.3 = and short %t1.1, 0xFF00
        ret short %tmp.3
}

This implements cast-set.ll:test4 and test5
