c1a2be18ea Implement vaarg instruction. This is not quite perfect: 2003-08-11-VaListArg 
still causes a crash. But it's better than before.

dbde1ae7a0 popStackAndReturnValueToCaller() must advance instruction pointer to normal 
destination, if returning from an invoke.

Implement 'unwind' instruction.

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.

3b3640a373 Shorten and correct some function-header comments. 
Make "verbose" output MUCH nicer. Now it tells you when you are linking a
bytecode file, or an archive, and whether it's because you called it by name,
or because you gave it a -l option, and it says "Trying" before it takes
action and prints a message in the past tense afterwards.

Make LinkFiles not skip the first file in Files.

Make LinkFiles warn you if it can't find a file and LLVM_LIB_SEARCH_PATH is
unset.

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.
