2dbfa03fd8 Change the RaiseAllocations pass to be a Pass instead of a BasicBlock pass. 
This makes it more efficient: it doesn't have to scan the whole program, so
it performs work proportional to the number of malloc/free calls in the
program, not the size of the program.

cfd67c96dc * Use alloca() to force GCC not to eliminate frame pointer 
* Break apart saving and restoring registers into separate functions
* Instead of saving single and double FP registers, just save the double
  registers -- aliasing helps preserve the single FP registers as well.
* Request just as much memory for a stub as we actually use

aeb54b882c Add support for the llvm.unwind intrinsic, which we codegen to just do an abort 
until we implement unwinding.
Add support for the invoke instruction, which codegens just like a call with
a branch after it.

The end effect of this change is that programs using the invoke instruction,
but never unwinding, will work fine.  Programs that unwind will abort until
we get unwind support.

other things, but only if the LLVM code shared data structures with native code.

c48ef2ae36 lib/Support/CommandLine.cpp: 
Many changes suggested by Chris. It's okay, I'll recover from the emotional
damage...maybe someday. :-)

Collapse ParseCStringVector into ParseStringVector.  Comment it.
Make it take a const input.
Use std::string::npos instead of -1 (what a mouthful!)
Make ParseEnvironmentOptions take const inputs.
Check its args at the very beginning.
Strdup all the contents of newArgv and free them all at the end.

include/Support/CommandLine.h:
Constify progName and envVar arguments to ParseEnvironmentOptions().

d2dfc9628d Now that the JIT memory manager allocates as many bytes as necessary rather than 
rounding up to a page, we need to request (num instrs * 4) bytes. However, I
think that 64 bytes is overkill for the stub function.

0870e970ff 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.

e895a740c7 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.

  the call to addFunctionReference() because the actual call instruction is 10
  instructions away (thanks to 64-bit address construction)

a2dd745613 All callers of these methods actually wanted them to preserve the flags, 
so get rid of the def/use parameters that were getting passed in.

**** This now changes the semantics of these methods to preserve the flags,
     not clobber them!

72666e6c30 Add all arithmetic operators to ConstantExprToString(). 
Note that some generated operators (like &, | or ^) may
not be supported by the assembler -- but if they've got
this far, it's better to generate them and let the assembler decide.
