* Fix the last -Wnon-pod-memset I'm seeing. This is benign, but appearsChandler Carruth2011-04-281-1/+1
| | | | | | | | | | | | | a bit more sinister as the memset doesn't do what the constructor does. There seems to be a cleaner solution than a cast here though, instead we can point the memset destination into the union its actually trying to clear. An alternative is to point to the Untyped member of this union. Review appreciated, and if that is cleaner I'm happy to switch. All of these should be functionally equivalent to the original code. llvm-svn: 130395

* MCJIT lazy relocation resolution and symbol address re-assignment.Jim Grosbach2011-04-121-98/+234
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add handling for tracking the relocations on symbols and resolving them. Keep track of the relocations even after they are resolved so that if the RuntimeDyld client moves the object, it can update the address and any relocations to that object will be updated. For our trival object file load/run test harness (llvm-rtdyld), this enables relocations between functions located in the same object module. It should be trivially extendable to load multiple objects with mutual references. As a simple example, the following now works (running on x86_64 Darwin 10.6): $ cat t.c int bar() { return 65; } int main() { return bar(); } $ clang t.c -fno-asynchronous-unwind-tables -o t.o -c $ otool -vt t.o t.o: (__TEXT,__text) section _bar: 0000000000000000 pushq %rbp 0000000000000001 movq %rsp,%rbp 0000000000000004 movl $0x00000041,%eax 0000000000000009 popq %rbp 000000000000000a ret 000000000000000b nopl 0x00(%rax,%rax) _main: 0000000000000010 pushq %rbp 0000000000000011 movq %rsp,%rbp 0000000000000014 subq $0x10,%rsp 0000000000000018 movl $0x00000000,0xfc(%rbp) 000000000000001f callq 0x00000024 0000000000000024 addq $0x10,%rsp 0000000000000028 popq %rbp 0000000000000029 ret $ llvm-rtdyld t.o -debug-only=dyld ; echo $?

* Tidy up a bit now that we're using the MemoryManager interface.Jim Grosbach2011-04-121-7/+1

* Just because a GlobalVariable's initializer is [N x { i32, void ()* }] doesn'tNick Lewycky2011-04-111-1/+5
| | | | | | | | | | | | mean that it has to be ConstantArray of ConstantStruct. We might have ConstantAggregateZero, at either level, so don't crash on that. Also, semi-deprecate the sentinal value. The linker isn't aware of sentinals so we end up with the two lists appended, each with their "sentinals" on them. Different parts of LLVM treated sentinals differently, so make them all just ignore the single entry and continue on with the rest of the list. llvm-svn: 129307

* RuntimeDyld should use the memory manager API.Jim Grosbach2011-04-062-91/+88
| | | | | | | | | | Start teaching the runtime Dyld interface to use the memory manager API for allocating space. Rather than mapping directly into the MachO object, we extract the payload for each object and copy it into a dedicated buffer allocated via the memory manager. For now, just do Segment64, so this works on x86_64, but not yet on ARM. llvm-svn: 128973

* Layer the memory manager between the JIT and the runtime Dyld.Jim Grosbach2011-04-043-18/+21
| | | | | | | | | | | 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

* 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

* Add simple arg passing to MC-JIT and support for exit() call.Jim Grosbach2011-03-223-4/+115
| | | | | | | | | | | | | 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

* Hook up the MCJIT to the RuntimeDyld library.Jim Grosbach2011-03-223-3/+22
| | | | | | | | 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
