* Convert assert(0) to llvm_unreachableCraig Topper2012-02-071-2/+1
| | | | llvm-svn: 149967
* More dead code removal (using -Wunreachable-code)David Blaikie2012-01-201-2/+0
| | | | llvm-svn: 148578
* Fix MCJIT memory leak of owned TargetMachine.Jim Grosbach2012-01-171-0/+1
| | | | | | | The JIT is expected to take ownership of the TM that's passed in. The MCJIT wasn't freeing it, resulting in leaks. llvm-svn: 148356
* ExecutionEngine: refactor interfaceDylan Noblesmith2011-12-121-5/+2
| | | | | | | | The OptLevel is now redundant with the TargetMachine*. And selectTarget() isn't really JIT-specific and could probably get refactored into one of the lower level libraries. llvm-svn: 146355
* Sink codegen optimization level into MCCodeGenInfo along side relocation modelEvan Cheng2011-11-161-1/+1
| | | | | | | and code model. This eliminates the need to pass OptLevel flag all over the place and makes it possible for any codegen pass to use this information. llvm-svn: 144788
* MCJIT initialization TargetDataDanil Malyshev2011-09-301-0/+1

* Fix the asserts in lib/Target/X86/X86ELFWriterInfo.cpp andRichard Trieu2011-09-101-1/+1
| | | | | | | | | | | | lib/ExecutionEngine/MCJIT/MCJIT.cpp from: assert("error"); to: assert(0 && "error"); llvm-svn: 139456
* land David Blaikie's patch to de-constify Type, with a few tweaks.Chris Lattner2011-07-181-2/+2
| | | | llvm-svn: 135375
* Avoid a Twine that referenced a tmp (which proceded to go out of scope beforeJim Grosbach2011-05-191-5/+3
| | | | | | the Twine was used). llvm-svn: 131612
* Restore sanity to 131601.Jim Grosbach2011-05-181-2/+3

* Objective C functions may use a magic '\1' on the name. Handle that whenJim Grosbach2011-05-181-1/+6

* ExecutionEngine: push TargetMachine creation into clients (v2)Dylan Noblesmith2011-05-131-14/+1
| | | | | | | | In particular, into EngineBuilder. This should only impact the private API between the EE and EB classes, not external clients, since JITCtor and MCJITCtor are both protected members. llvm-svn: 131317
* ExecutionEngine: fix JIT/MCJIT selectTarget() duplication (v2)Dylan Noblesmith2011-05-131-1/+2
| | | | | | | This prepares for making JITCtor/MCJITCtor take a TargetMachine* directly from clients like EngineBuilder. llvm-svn: 131316
* The MCJIT memory manager needs to initialize its Module member.Jim Grosbach2011-05-121-1/+1
| | | | llvm-svn: 131234
* Revert ExecutionEngine patches, they either failed to build or broke unit tests.Jakob Stoklund Olesen2011-05-071-1/+13
| | | | | | Please ensure the build is clean and tests are passing when recommitting. llvm-svn: 131044

* 80-col fix.Eric Christopher2011-04-221-1/+1

* Layer the memory manager between the JIT and the runtime Dyld.Jim Grosbach2011-04-041-4/+7
| | | | | | | | | | | The JITMemory manager references LLVM IR constructs directly, while the runtime Dyld works at a lower level and can handle objects which may not originate from LLVM IR. Introduce a new layer for the memory manager to handle the interface between them. For the MCJIT, this layer will be almost entirely simply a call-through w/ translation between the IR objects and symbol names. llvm-svn: 128851
* Instantiate a JITMemoryManager for MCJIT DyldJim Grosbach2011-03-291-1/+1
| | | | llvm-svn: 128485
* Fix double-free of Module.Jim Grosbach2011-03-231-1/+0
| | | | | | | | The ExecutionEngine constructor already added the module, so there's no need to call addModule() directly. Doing so causes a double-free of the Module at program termination. llvm-svn: 128171
* Make sure to report any errors from the runtime dyld.Jim Grosbach2011-03-231-1/+2
| | | | llvm-svn: 128160
* Add simple arg passing to MC-JIT and support for exit() call.Jim Grosbach2011-03-221-4/+104
| | | | | | | | | | | | | Support argument passing simple, common, prototypes directly. More complicated scenarios will require building up a stub function, which the MC-JIT isn't set up to handle yet. Add Intercept.cpp, which is just a copy from ExecutionEngine/JIT for now, to handle looking looking up external symbol names. This probably more properly belongs as part of RuntimeDyld. It'll migrate there as things flesh out more fully. llvm-svn: 128090
* Fix comment in header.Eric Christopher2011-03-221-1/+1
| | | | llvm-svn: 128077
* Hook up the MCJIT to the RuntimeDyld library.Jim Grosbach2011-03-221-1/+11
| | | | | | | | Lots of cleanup to make the interfaces prettier, use the JITMemoryManager, handle multiple functions and modules, etc.. This gets far enough that the MCJIT compiles and runs code, though. llvm-svn: 128052
* Silence a warning.Jim Grosbach2011-03-181-1/+1
| | | | llvm-svn: 127918
* Beginnings of MC-JIT code generation.Jim Grosbach2011-03-181-5/+27
| | | | | | | | | | | Proof-of-concept code that code-gens a module to an in-memory MachO object. This will be hooked up to a run-time dynamic linker library (see: llvm-rtdyld for similarly conceptual work for that part) which will take the compiled object and link it together with the rest of the system, providing back to the JIT a table of available symbols which will be used to respond to the getPointerTo*() queries. llvm-svn: 127916
* Merge System into Support.Michael J. Spencer2010-11-291-1/+1
| | | | llvm-svn: 120298
* MCJIT: Stub out MCJIT implementation, still doesn't do anything useful.Daniel Dunbar2010-11-171-0/+92
