* Revert patches to add case-range support for PR1255.Bob Wilson2013-09-091-33/+4
| | | | | | | | | | | | | | | | | The work on this project was left in an unfinished and inconsistent state. Hopefully someone will eventually get a chance to implement this feature, but in the meantime, it is better to put things back the way the were. I have left support in the bitcode reader to handle the case-range bitcode format, so that we do not lose bitcode compatibility with the llvm 3.3 release.

* Fixed RuntimeDyldELF absolute relocations.Richard Mitton2013-08-161-1/+11
| | | | | | | | | If an ELF relocation is pointed at an absolute address, it will have a symbol ID of zero. RuntimeDyldELF::processRelocationRef was not previously handling this case, and was instead trying to handle it as a section-relative fixup. I think this is the right fix here, but my elf-fu is poor on some of the more exotic platforms, so I'd appreciate it if anyone with greater knowledge could verify this. llvm-svn: 188572
* Support X86_64_GOTLoad relocations in RuntimeDyldMachO by treating them theLang Hames2013-08-151-4/+4
| | | | | | | | | | | | | | | | 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. This fixes <rdar://problem/14651564>. llvm-svn: 188499

* [PowerPC] Support powerpc64le as a syntax-checking target.Bill Schmidt2013-07-263-4/+5
| | | | | | | | | | | | | | | | | | | | | | | This patch provides basic support for powerpc64le as an LLVM target. However, use of this target will not actually generate little-endian code. Instead, use of the target will cause the correct little-endian built-in defines to be generated, so that code that tests for __LITTLE_ENDIAN__, for example, will be correctly parsed for syntax-only testing. Code generation will otherwise be the same as powerpc64 (big-endian), for now. The patch leaves open the possibility of creating a little-endian PowerPC64 back end, but there is no immediate intent to create such a thing. The LLVM portions of this patch simply add ppc64le coverage everywhere that ppc64 coverage currently exists. There is nothing of any import worth testing until such time as little-endian code generation is implemented. In the corresponding Clang patch, there is a new test case variant to ensure that correct built-in defines for little-endian code are generated. llvm-svn: 187179
* AArch64: don't mask off shift bits when processing JIT relocations.Tim Northover2013-07-251-4/+4
| | | | | | | This should actually make the MCJIT tests pass again on AArch64. I don't know how I missed their failure before. llvm-svn: 187120
* [mips] Use pristine object file while processing relocations.Akira Hatanaka2013-07-241-7/+20
| | | | | | | | | | | | | | | | | | | Similar to ARM change r182800, dynamic linker will read bits/addends from the original object rather than from the object that might have been patched previously. For the purpose of relocations for MCJIT stubs on MIPS, we internally use otherwise unused MIPS relocations. The change also enables MCJIT unit tests for MIPS (EL/BE), and the following two tests now pass: - MCJITTest.return_global and - MCJITTest.multiple_functions. These issues have been tracked as Bug 16250. Patch by Petar Jovanovic. llvm-svn: 187019

* AArch64: correct CodeGen of MOVZ/MOVK combinations.Tim Northover2013-07-011-7/+8
| | | | | | | | | | | | According to the AArch64 ELF specification (4.6.8), it's the assembler's responsibility to make sure the shift amount is correct in relocated MOVZ/MOVK instructions. This wasn't being obeyed by either the MCJIT CodeGen or RuntimeDyldELF (which happened to work out well for JIT tests). This commit should make us compliant in this area. llvm-svn: 185360

* Enable FastISel on ARM for Linux and NaCl, not MCJITJF Bastien2013-06-141-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a resubmit of r182877, which was reverted because it broken MCJIT tests on ARM. The patch leaves MCJIT on ARM as it was before: only enabled for iOS. I've CC'ed people from the original review and revert. FastISel was only enabled for iOS ARM and Thumb2, this patch enables it for ARM (not Thumb2) on Linux and NaCl, but not MCJIT. Thumb2 support needs a bit more work, mainly around register class restrictions. The patch punts to SelectionDAG when doing TLS relocation on non-Darwin targets. I will fix this and other FastISel-to-SelectionDAG failures in a separate patch. The patch also forces FastISel to retain frame pointers: iOS always keeps them for backtracking (so emitted code won't change because of this), but Linux was getting much worse code that was incorrect when using big frames (such as test-suite's lencod). I'll also fix this in a later patch, it will probably require a peephole so that FastISel doesn't rematerialize frame pointers back-to-back. The test changes are straightforward, similar to: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20130513/174279.html They also add a vararg test that got dropped in that change. I ran all of lnt test-suite on A15 hardware with --optimize-option=-O0 and all the tests pass. All the tests also pass on x86 make check-all. I also re-ran the check-all tests that failed on ARM, and they all seem to pass. llvm-svn: 183966

* Handle relocations that don't point to symbols.Rafael Espindola2013-06-052-11/+8
| | | | | | | | In ELF (as in MachO), not all relocations point to symbols. Represent this properly by using a symbol_iterator instead of a SymbolRef. Update llvm-readobj ELF's dumper to handle relocatios without symbols. llvm-svn: 183284

* Update RuntimeDyldELF::findOPDEntrySection the new relocation iterators.Rafael Espindola2013-06-031-3/+7
| | | | | | | This was missing from r182908. I didn't noticed it at the time because the MCJIT tests were disabled when building with cmake on ppc64 (which I fixed in r183143). llvm-svn: 183147
* Change how we iterate over relocations on ELF.Rafael Espindola2013-05-301-4/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | For COFF and MachO, sections semantically have relocations that apply to them. That is not the case on ELF. In relocatable objects (.o), a section with relocations in ELF has offsets to another section where the relocations should be applied. In dynamic objects and executables, relocations don't have an offset, they have a virtual address. The section sh_info may or may not point to another section, but that is not actually used for resolving the relocations. This patch exposes that in the ObjectFile API. It has the following advantages: * Most (all?) clients can handle this more efficiently. They will normally walk all relocations, so doing an effort to iterate in a particular order doesn't save time. * llvm-readobj now prints relocations in the same way the native readelf does. * probably most important, relocations that don't point to any section are now visible. This is the case of relocations in the rela.dyn section. See the updated relocation-executable.test for example. llvm-svn: 182908
* ARM: use pristine object file while processing relocationsTim Northover2013-05-281-15/+23
| | | | | | | | | | | | | | Previously we would read-modify-write the target bits when processing relocations for the MCJIT. This had the problem that when relocations were processed multiple times for the same object file (as they can be), the result is not idempotent and the values became corrupted. The solution to this is to take any bits used in the destination from the pristine object file as LLVM emitted it. This should fix PR16013 and remote MCJIT on ARM ELF targets. llvm-svn: 182800

* AArch64: make RuntimeDyld relocations idempotentTim Northover2013-05-191-2/+22
| | | | | | | | | | AArch64 ELF uses .rela relocations so there's no need to actually make use of the bits we're setting in the destination However, we should make sure all bits are cleared properly since multiple runs of resolveRelocations are possible and these could combine to produce invalid results if stale versions remain in the code. llvm-svn: 182214
