Chris Lattner 0b2de9f2d4 remove the intrinsiclowering hook 
llvm-svn: 26970
 2006-03-23 05:22:51 +00:00
Chris Lattner 2d52c1b8b9 Eliminate the dependency of ExecutionEngine on the JIT/Interpreter libraries. 
Now you can build a tool with just the JIT or just the interpreter.

llvm-svn: 26946
 2006-03-22 06:07:50 +00:00
Chris Lattner faae50b66b Add a helper method for running static ctors/dtors in the module. 
llvm-svn: 26619
 2006-03-08 18:42:46 +00:00
Jeff Cohen 69e849014c Teach the interpreter to handle global variables that are added to a module after 
interpretation has begun.  The JIT already handles this situation correctly, and
the interpreter can already handle new functions being added.

 2006-02-07 05:11:57 +00:00
Robert Bocchino 69d621387c Fixed InitializeMemory to handle ConstantPacked. 
llvm-svn: 25481
 2006-01-20 18:18:40 +00:00
Chris Lattner a551033ea8 Fix a nasty bug that was causing miscompilation of global variables 
on big endian 32-bit targets in some cases (e.g. PPC).  This fixes several
PPC JIT failures.

Reid Spencer 79876f52aa For PR540: 
This patch completes the changes for making lli thread-safe. Here's the list
of changes:
* The Support/ThreadSupport* files were removed and replaced with the
  MutexGuard.h file since all ThreadSupport* declared was a Mutex Guard.
  The implementation of MutexGuard.h is now based on sys::Mutex which hides
  its implementation and makes it unnecessary to have the -NoSupport.h and
  -PThreads.h versions of ThreadSupport.

* All places in ExecutionEngine that previously referred to "Mutex" now
  refer to sys::Mutex

* All places in ExecutionEngine that previously referred to "MutexLocker"
  now refer to MutexGuard (this is frivolous but I believe the technically
  correct name for such a class is "Guard" not a "Locker").

These changes passed all of llvm-test. All we need now are some test cases
that actually use multiple threads.

Chris Lattner 8ffb66111c fix long lines 
llvm-svn: 22369
 2005-07-11 02:49:16 +00:00
Chris Lattner 646c0f0234 Fix a really horrible problem that causes the JIT to miscompile any program 
that use 64-bit integers on 32-bit hosts.

llvm-svn: 21886

Misha Brukman 835702a094 Remove trailing whitespace 
llvm-svn: 21420
 2005-04-21 22:36:52 +00:00
Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!

llvm-svn: 20354
 2005-02-27 19:06:10 +00:00
Chris Lattner 45a6a18393 This is no longer needed. Global variables with undef initializers can be 
initialized to anything, including garbage.

Chris Lattner 834b1272f3 Make the JIT zero out globals with memset instead of an element at a time. This 
should speed it up a bit on a lot of programs

llvm-svn: 11043
 2004-02-01 01:07:25 +00:00
Chris Lattner 748e857996 Add new ExecutionEngine::getGlobalValueAtAddress method, which can efficiently 
turn a memory address back into the LLVM global object that starts at that
address.  Note that this won't cause any additional datastructures to be built
for clients of the EE that don't need this information.

Also modified some code to not access the GlobalAddress map directly.

llvm-svn: 10674
 2003-12-31 20:21:04 +00:00

Misha Brukman e37fb9ddc5 Don't release the Module, as that invalidates the Module* within the 
ModuleProvider, which has bad consequences in lli::callAsMain() which tries to
access that same Module*.

llvm-svn: 9205
 2003-10-17 18:31:59 +00:00

Build ExecutionEngine as library.

llvm-svn: 8370
 2003-09-05 19:39:22 +00:00
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".

Mung some comments.
Get rid of interpreter's PROFILE_STRUCTURE_FIELDS and PerformExitStuff
 which have been disabled forever.
Get rid of -abort-on-exception (make it always on).
Get rid of user interaction stuff (debug mode innards).
Simplify Interpreter's callMainFunction().

llvm-svn: 8344

Brian Gaeke 4bd3bd5b5a ExecutionEngine.cpp: Move execution engine creation stuff into a new 
static method here.

own subclass.

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

Chris Lattner 69cab0dd52 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.

 2003-08-24 19:55:26 +00:00

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.

llvm-svn: 7176
