* Re-factored RuntimeDyLd:Danil Malyshev2012-03-30
| | | | | | | | | | | | | | | 1. The main works will made in the RuntimeDyLdImpl with uses the ObjectFile class. RuntimeDyLdMachO and RuntimeDyLdELF now only parses relocations and resolve it. This is allows to make improvements of the RuntimeDyLd more easily. In addition the support for COFF can be easily added. 2. Added ARM relocations to RuntimeDyLdELF. 3. Added support for stub functions for the ARM, allowing to do a long branch. 4. Added support for external functions that are not loaded from the object files, but can be loaded from external libraries. Now MCJIT can correctly execute the code containing the printf, putc, and etc. 5. The sections emitted instead functions, thanks Jim Grosbach. MemoryManager.startFunctionBody() and MemoryManager.endFunctionBody() have been removed. 6. MCJITMemoryManager.allocateDataSection() and MCJITMemoryManager. allocateCodeSection() used JMM->allocateSpace() instead of JMM->allocateCodeSection() and JMM->allocateDataSection(), because I got an error: "Cannot allocate an allocated block!" with object file contains more than one code or data sections. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153754 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert a series of commits to MCJIT to get the build working in CMakeChandler Carruth2012-03-22
| | | | | | | | | | | | | | | (and hopefully on Windows). The bots have been down most of the day because of this, and it's not clear to me what all will be required to fix it. The commits started with r153205, then r153207, r153208, and r153221. The first commit seems to be the real culprit, but I couldn't revert a smaller number of patches. When resubmitting, r153207 and r153208 should be folded into r153205, they were simple build fixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153241 91177308-0d34-0410-b5e6-96231b3b80d8

* MCJIT support for non-function sections.Jim Grosbach2012-01-16
| | | | | | | | | | | | | | | | Move to a by-section allocation and relocation scheme. This allows better support for sections which do not contain externally visible symbols. Flesh out the relocation address vs. local storage address separation a bit more as well. Remote process JITs use this to tell the relocation resolution code where the code will live when it executes. The startFunctionBody/endFunctionBody interfaces to the JIT and the memory manager are deprecated. They'll stick around for as long as the old JIT does, but the MCJIT doesn't use them anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148258 91177308-0d34-0410-b5e6-96231b3b80d8

* MCJIT lazy relocation resolution and symbol address re-assignment.Jim Grosbach2011-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 $?

* RuntimeDyld should use the memory manager API.Jim Grosbach2011-04-06
| | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128973 91177308-0d34-0410-b5e6-96231b3b80d8

* Layer the memory manager between the JIT and the runtime Dyld.Jim Grosbach2011-04-04
| | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128851 91177308-0d34-0410-b5e6-96231b3b80d8
