* AArch64/ARM64: move ARM64 into AArch64's placeTim Northover2014-05-24
| | | | | | | | | | | | | | | This commit starts with a "git mv ARM64 AArch64" and continues out from there, renaming the C++ classes, intrinsics, and other target-local objects for consistency. "ARM64" test directories are also moved, and tests that began their life in ARM64 use an arm64 triple, those from AArch64 use an aarch64 triple. Both should be equivalent though. This finishes the AArch64 merge, and everyone should feel free to continue committing as normal now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209577 91177308-0d34-0410-b5e6-96231b3b80d8
* [RuntimeDyld] Teach RuntimeDyldMachO how to handle scattered VANILLA relocs onLang Hames2014-05-22
| | | | | | | | | | | | | | | | | | | | | | i386. This fixes two more MCJIT regression tests on i386: ExecutionEngine/MCJIT/2003-05-06-LivenessClobber.ll ExecutionEngine/MCJIT/2013-04-04-RelocAddend.ll The implementation of processScatteredVANILLA is tasteless (*ba-dum-ching*), but I'm working on a substantial tidy-up of RuntimeDyldMachO that should improve things. This patch also fixes a type-o in RuntimeDyldMachO::processSECTDIFFRelocation, and teaches that method to skip over the PAIR reloc following the SECTDIFF. <rdar://problem/16961886> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209478 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM64: initial backend importTim Northover2014-03-29
| | | | | | | | | | | | This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205090 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters.

* Support X86_64_GOTLoad relocations in RuntimeDyldMachO by treating them theLang Hames2013-08-15
| | | | | | | | | | | | | | | | | | same way as X86_64_GOT relocations. The 'Load' part of GOTLoad is just an optimization hint for the linker anyway, and can be safely ignored. This patch also fixes some minor issues with the relocations introduced while processing an X86_64_GOT[Load]: the addend for the GOT entry should always be zero, and the addend for the replacement relocation at the original offset should be the same as the addend of the relocation being replaced. I haven't come up with a good way of testing this yet, but I'm working on it.

* Replace ObjRelocationInfo with relocation_iterator.Rafael Espindola2013-04-29
| | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180711 91177308-0d34-0410-b5e6-96231b3b80d8

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-03
| | | | | | | | | | | | | | | | | 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. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167304 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | 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
