* Put RTDyldMemoryManager into its own file, and make it linked into Filip Pizlo2013-05-211-2/+0
| | | | | | | | | | | | | | | | | | libExecutionEngine. Move method implementations that aren't specific to allocation out of SectionMemoryManager and into RTDyldMemoryManager. This is in preparation for exposing RTDyldMemoryManager through the C API. This is a fixed version of r182407 and r182411. That first revision broke builds because I forgot to move the conditional includes of various POSIX headers from SectionMemoryManager into RTDyldMemoryManager. Those includes are necessary because of how getPointerToNamedFunction works around the glibc libc_nonshared.a thing. The latter revision still broke things because I forgot to include llvm/Config/config.h. llvm-svn: 182418

* Add EH support to the MCJIT.Rafael Espindola2013-05-051-3/+11
| | | | | | | | | This gets exception handling working on ELF and Macho (x86-64 at least). Other than the EH frame registration, this patch also implements support for GOT relocations which are used to locate the personality function on MachO. llvm-svn: 181167
* AArch64: add stubs to support long function calls on MCJITTim Northover2013-05-041-1/+19
| | | | | | | | | | | | | | | | | | | | As with global accesses, external functions could exist anywhere in memory. Therefore the stub must create a complete 64-bit address. This patch implements the fragment as (roughly): movz x16, #:abs_g3:somefunc movk x16, #:abs_g2_nc:somefunc movk x16, #:abs_g1_nc:somefunc movk x16, #:abs_g0_nc:somefunc br x16 In principle we could save 4 bytes by using a literal-load instead, but it is unclear that would be more efficient and can only be tested when real hardware is readily available. This allows (for example) the MCJIT test 2003-05-07-ArgumentTest to pass on AArch64. llvm-svn: 181133
* [SystemZ] Add MCJIT supportRichard Sandiford2013-05-031-0/+13
| | | | | | | | Another step towards reinstating the SystemZ backend. I'll commit the configure changes separately (TARGET_HAS_JIT etc.), then commit a patch to enable the MCJIT tests on SystemZ. llvm-svn: 181015
* Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola2013-04-291-1/+2
| | | | | | | | | | | | | For regular object files this is only meaningful for common symbols. An object file format with direct support for atoms should be able to provide alignment information for all symbols. This replaces getCommonSymbolAlignment and fixes test-common-symbols-alignment.ll on darwin. This also includes a fix to MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common (already tested by existing mcjit tests now that it is used). llvm-svn: 180736

* Propagate relocation info to resolveRelocation.Rafael Espindola2013-04-291-17/+5

* Replace ObjRelocationInfo with relocation_iterator.Rafael Espindola2013-04-291-12/+2
| | | | | | | | | | | For MachO we need information that is not represented in ObjRelocationInfo. Instead of copying the bits we think are needed from a relocation_iterator, just pass the relocation_iterator down to the format specific functions. No functionality change yet as we still drop the information once processRelocationRef returns. llvm-svn: 180711

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-2/+3
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131

* Add a method to indicate section address re-assignment is finished.Andrew Kaylor2012-11-051-7/+9
| | | | | | Prior to this patch RuntimeDyld attempted to re-apply relocations every time reassignSectionAddress was called (via MCJIT::mapSectionAddress). In addition to being inefficient and redundant, this led to a problem when a section was temporarily moved too far away from another section with a relative relocation referencing the section being moved. To fix this, I'm adding a new method (finalizeObject) which the client can call to indicate that it is finished rearranging section addresses so the relocations can safely be applied. llvm-svn: 167400
* Change resolveRelocation parameters so the relocations can find placeholder ↵Andrew Kaylor2012-11-021-3/+3
| | | | | | | | values in the original object buffer. Some ELF relocations require adding the a value to the original contents of the object buffer at the specified location. In order to properly handle multiple applications of a relocation, the RuntimeDyld code should be grabbing the original value from the object buffer and writing a new value into the loaded section buffer. This patch changes the parameters passed to resolveRelocations to accommodate this need. llvm-svn: 167304

The GDB JIT debugging integration support works by registering a loaded object image with a pre-defined function that GDB will monitor if GDB is attached.

* Re-factored RuntimeDyLd:Danil Malyshev2012-03-301-25/+270
| | | | | | | | | | | | | | | 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. llvm-svn: 153754

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. llvm-svn: 153241

* MCJIT support for non-function sections.Jim Grosbach2012-01-161-10/+13
| | | | | | | | | | | | | | | | 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. llvm-svn: 148258
