94184ddd7b Consult the target data, not the module, about how large the current pointer 
size is.  This ensures that if the module has no specified pointer size that
things will work correctly.

8bc390da1b The JIT now passes the environment pointer to the main() function when it 
starts a program.  This allows the GNU env program to compile and JIT under
LLVM.

442175ec3b * Stop hard-coding a value for beginning of emitted code on Sparc since we can 
now handle far calls (i.e., beyond the 30-bit limit in call instructions).
* As a side-effect, this allows us to unify and clean up the mmap() call and
  code around it.

c0193ca460 Add ability for external C code to get pointers to functions given their name. 
This us used by bugpoint -- when code is compiled to a shared object to be
JITted, it must use the JIT's lazy resolution method to find function addresses,
because some functions will not be available at .so load time, as they are in
the bytecode file.

755aa86ca3 Cleaned up the code which chooses the appropriate value for the file descriptor 
to pass to dlsym() -- Linux/x86 wants 0 while Sparc/Solaris wants RTLD_SELF,
which is not zero. Thanks to Chris for the suggestion.

45dc28808e Clean up my last checkin: code is easier to read and explains the differences in 
usage of the special file handle RTLD_SELF on Sparc/Solaris vs. 0 on Linux/x86.

6a087a3a2f On Sparc/Solaris, the special handle RTLD_SELF is used as a handle referring to 
the program's executing image, not 0 as it is on Linux/x86 and possibly other
systems.

009e42dd43 * If compiling on X86 or Sparc, automagically enable the JIT for that arch 
* Setting ENABLE_X86_JIT or ENABLE_SPARC_JIT on the `make' command-line will
  force the inclusion of that JIT on a different architecture
* If neither JIT is enabled (e.g., compiling on a different architecture), the
  -march option will not be available to LLI.
* As a side effect of the $ARCH variable, the Sparc LLI can now link just a bit
  faster by not including the x86 library.

04d082abe5 Add #ifdef hack for MAP_ANONYMOUS being spelled MAP_ANON on some platforms. 
(We're already talking about autoconf'ing this, so I'm assuming this hack
will be short-lived...I just don't want it to get lost in my working files.)

0c7e4fdfa2 Do not link in the Sparc JIT when building on X86. Eventually the sparc will not 
link in the X86 JIT either, but this makes testing easier.

For some reason, the sparc JIT was breaking the X86 JIT when it was linked in. :(

1a3c1a6208 ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: 
The JIT is designed to code-generate a function at-a-time. That means that any
pass can only make local changes to its function. Period.

Because the Sparc PreSelection pass claims to be a BasicBlock pass while adding
globals to the Module, it cannot be run with the other passes, because by this
time, the globals have been output already by the JIT, and the addresses of any
globals appearing AFTER this point are not recognized.

However, the PreSelection pass is a requirement for correctness in the Sparc
codegen path, so it MUST be run.
