Chris Lattner 4c522b9434 reset errno to zero on entry to the application's main function. This fixes
MultiSource/Applications/minisat in the JIT.

Note that the libsystem stuff should ideally never modify errno.  :(

Reid Spencer fe5550b2cf Obtain the exit function before execution just in case the module
disappears before we get to calling the exit function.

Reid Spencer e586f2e7f7 1. Handle errors around the ModuleProvider. This is necessary since it is
reading bytecode.
2. The interpreter can delete the ModuleProvider and replace it with
   another so don't depend on it being around after the EE is created.
3. Don't just run llvm_shutdown on exit but actually delete the EE as well.
   This cleans up a vast amount of memory (but not all) that EE retained
   through exit.

Chris Lattner a0e49f2ead push bytecode decompressor out through APIs. Now the bytecode reader
api's look like this:

ModuleProvider *getBytecodeModuleProvider(
  const std::string &Filename,  ///< Name of file to be read
  BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer,
  std::string* ErrMsg = 0,      ///< Optional error message holder
  BytecodeHandler* H = 0        ///< Optional handler for reader events
);

This is ugly, but allows a client to say:

  getBytecodeModuleProvider("foo", 0);

If they do this, there is no dependency on the compression libraries, saving
codesize.

Chris Lattner e05182cd1e fix atexit. This is an overcomplex way of calling exit, but it is required,
as the jit intercepts exit calls to implement atexit handlers.  This
fixes SingleSource/UnitTests/2003-05-14-AtExit

Chris Lattner ef2d8ca0b6 If a module has a main, but it is defined externally, refuse to run it.
Attempting to run it will find lli's main, which isn't the desired effect.

Jeff Cohen 11e26b52b2 When a function takes a variable number of pointer arguments, with a zero
pointer marking the end of the list, the zero *must* be cast to the pointer
type.  An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.

The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

  abort with a useless message but indicate than an unhandled exception was
  generated.

Brian Gaeke a7669038fc Make CreateArgv part of lli rather than part of ExecutionEngine.
Switch Interpreter and JIT's "run" methods to take a Function and a vector of
 GenericValues.
Move (almost all of) the stuff that constructs a canonical call to main()
 into lli (new methods "callAsMain", "makeStringVector").
Nuke getCurrentExecutablePath(), enableTracing(), getCurrentFunction(),
 isStopped(), and many dead decls from interpreter.
Add linux strdup() support to interpreter.
Make interpreter's atexit handler runner and JIT's runAtExitHandlers() look
 more alike, in preparation for refactoring.
atexit() is spelled "atexit", not "at_exit".
