Brian Gaeke 4bd3bd5b5a ExecutionEngine.cpp: Move execution engine creation stuff into a new 
static method here.
 Remove some extra blank lines.
ExecutionEngine.h: Add its prototype.
lli.cpp: Call it.

Make creation method for each type of EE into a static method of its
own subclass.

Interpreter/Interpreter.cpp: ExecutionEngine::createInterpreter -->
 Interpreter::create
Interpreter/Interpreter.h: Likewise.
JIT/JIT.cpp: ExecutionEngine::createJIT --> VM::create
JIT/VM.h: Likewise.

Chris Lattner 69cab0dd52 Consult the target data, not the module, about how large the current pointer

John Criswell 71c3e6236f The JIT now passes the environment pointer to the main() function when it

Misha Brukman e47f069855 * 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.

Misha Brukman 057f460053 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.

Misha Brukman 1f6feb7bf4 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.

llvm-svn: 7204
 2003-07-18 18:33:38 +00:00
Misha Brukman 528a37621b 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.

llvm-svn: 7177
 2003-07-15 15:58:26 +00:00
Misha Brukman 7225461edf 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.

Misha Brukman 7dee443c1c * 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.

Chris Lattner d9cc372613 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. :(

Misha Brukman 0ccdecbdaa ::: 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.

Misha Brukman 1d443d1250 * 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.

Misha Brukman 905496e94f Sparc's dlsym() requires the special operand RTLD_SELF to find a symbol in the 
currently-running process.

llvm-svn: 6592
 2003-06-04 01:57:22 +00:00
Misha Brukman 6ac7fe7dc0 * 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.

Misha Brukman 80f0eb3a82 Link in Sparc libs for the JIT, even on X86 to be able to support debugging 
of Sparc JIT (printing out instrs) on X86. Con: this increases linking time.

llvm-svn: 6361
 2003-05-27 21:42:05 +00:00
Misha Brukman 56d27325c0 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...
