cf614a32d5 Removed debug print statement.

3a55e8aae4 * Institute a hack for the Sparc call to mmap() to get our generated code to be 
laid out closer to the VM so that calls to library functions (e.g. puts()) and
  callback (e.g.  JITResolver::CompilationCallback) fit into 30 bits of the call
  instruction.
* Abort if architecture is not yet supported (not X86 or Sparc) because it
  likely requires a different set of parameters to mmap() .
* Stop using hard-coded values for page size; use sysconf(_SC_PAGESIZE) instead.

88fe358f8a Sparc's dlsym() requires the special operand RTLD_SELF to find a symbol in the 
currently-running process.

906f5fa5c8 * Removed SparcEmitter.cpp; rolled into lib/Target/Sparc/SparcV9CodeEmitter.cpp 
* No more createX86Emitter() vs. createSparcEmitter() -- there can be only one
* As a result, the memory management semantics must be handled according to
  platform -- the parameters to mmap() are particularly sensitive to the host
  architecture.

24a26e58ef The flag modifications weren't picking up the old values of the 
flags before. Save them in a temporary variable, then restore them from the
temporary after creating the new constant.

bba1b6df9a Move target specific code to target files. The new MachineCodeEmitter 
class is actually target independent!

Modify new MachineOperand so that its flags match the old MachineOperand's
 flags, for the flags that matter.

417a7c06e8 Since malloc is no longer used, no need to free() memory. 
Fixed BasicBlock patching by supplying correct type for the displacement.

8e5bf70dff mmap() seems to be failing on Sparc, so just use malloc()/free() .

abb027cf41 Allow for specification of which JIT to run on the commandline. 
`lli -march=x86' or `lli -march=sparc' will forcefully select the JIT even on a
different platform. Running lli without the -march option will select the JIT
for the platform that it's currently running on.

Pro: can test Sparc JIT (debug printing mode) on X86 -- faster to compile/link
LLVM source base to test changes.
Con: Linking lli on x86 now pulls in all the Sparc libs -> longer link time
(but X86 can bear it, right?)

In the future, perhaps this should be a ./configure option to enable/disable
target JITting...

56adf152f6 Make sure that globals are emitted AFTER the passmanager is set up for the JIT, 
because the globals may refer to functions that need to be compiled!
