* Roll out r182411 and 182412 because it's still broken.Filip Pizlo2013-05-211-0/+2

* 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. That 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182411 91177308-0d34-0410-b5e6-96231b3b80d8

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182214 91177308-0d34-0410-b5e6-96231b3b80d8

* Change getRelocationAdditionalInfo to be ELF only.Rafael Espindola2013-05-091-4/+4

* Add EH support to the MCJIT.Rafael Espindola2013-05-056-7/+115
| | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181167 91177308-0d34-0410-b5e6-96231b3b80d8
* AArch64: implement 64-bit absolute relocation in MCJITTim Northover2013-05-041-0/+5
| | | | | | | | | This is about the simplest relocation, but surprisingly rare in actual code. It occurs in (for example) the MCJIT test test-ptr-reloc.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181134 91177308-0d34-0410-b5e6-96231b3b80d8
* AArch64: add stubs to support long function calls on MCJITTim Northover2013-05-043-2/+84
| | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181133 91177308-0d34-0410-b5e6-96231b3b80d8
* AArch64: implement relocations for global accessTim Northover2013-05-041-0/+31
| | | | | | | | | | | | | | | | | The large memory model (default and main viable for JIT) emits addresses in need of relocation as movz x0, #:abs_g3:somewhere movk x0, #:abs_g2_nc:somewhere movk x0, #:abs_g1_nc:somewhere movk x0, #:abs_g0_nc:somewhere To support this we must implement those four relocations in the dynamic loader. This allows (for example) the test-global.ll MCJIT test to pass on AArch64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181132 91177308-0d34-0410-b5e6-96231b3b80d8
* AArch64: implement first relocation required for MCJITTim Northover2013-05-042-0/+39
| | | | | | | | | | | R_AARCH64_PCREL32 is present in even trivial .eh_frame sections and so is required to compile any function without the "nounwind" attribute. This change implements very basic infrastructure in the RuntimeDyldELF file and allows (for example) the test-shift.ll MCJIT test to pass on AArch64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181131 91177308-0d34-0410-b5e6-96231b3b80d8

* Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola2013-04-294-18/+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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180736 91177308-0d34-0410-b5e6-96231b3b80d8

* Replace ObjRelocationInfo with relocation_iterator.Rafael Espindola2013-04-296-65/+59
| | | | | | | | | | | 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 llvm/Object/MachO.h in macho-dumper. Drop the old macho parser.Rafael Espindola2013-04-261-1/+1
| | | | | | | | | | | | | | | | | | | | | For Mach-O there were 2 implementations for parsing object files. A standalone llvm/Object/MachOObject.h and llvm/Object/MachO.h which implements the generic interface in llvm/Object/ObjectFile.h. This patch adds the missing features to MachO.h, moves macho-dump to use MachO.h and removes ObjectFile.h. In addition to making sure that check-all is clean, I checked that the new version produces exactly the same output in all Mach-O files in a llvm+clang build directory (including executables and shared libraries). To test the performance, I ran macho-dump over all the files in a llvm+clang build directory again, but this time redirecting the output to /dev/null. Both the old and new versions take about 4.6 seconds (2.5 user) to finish. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180624 91177308-0d34-0410-b5e6-96231b3b80d8

* Respect Addend when processing MCJIT relocations to local/global symbols.Ulrich Weigand2013-04-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the RuntimeDyldELF::processRelocationRef routine finds the target symbol of a relocation in the local or global symbol table, it performs a section-relative relocation: Value.SectionID = lsi->second.first; Value.Addend = lsi->second.second; At this point, however, any Addend that might have been specified in the original relocation record is lost. This is somewhat difficult to trigger for relocations within the code section since they usually do not contain non-zero Addends (when built with the default JIT code model, in any case). However, the problem can be reliably triggered by a relocation within the data section caused by code like: int test[2] = { -1, 0 }; int *p = &test[1]; The initializer of "p" will need a relocation to "test + 4". On platforms using RelA relocations this means an Addend of 4 is required. Current code ignores this addend when processing the relocation, resulting in incorrect execution. Fixed by taking the Addend into account when processing relocations to symbols found in the local or global symbol table. Tested on x86_64-linux and powerpc64-linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178869 91177308-0d34-0410-b5e6-96231b3b80d8

* [Object][ELF] Simplify ELFObjectFile by using ELFType.Michael J. Spencer2013-01-151-41/+41
| | | | | | | | | | | | | This simplifies the usage and implementation of ELFObjectFile by using ELFType to replace: <endianness target_endianness, std::size_t max_alignment, bool is64Bits> This does complicate the base ELF types as they must now use template template parameters to partially specialize for the 32 and 64bit cases. However these are only defined once. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172515 91177308-0d34-0410-b5e6-96231b3b80d8

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167400 91177308-0d34-0410-b5e6-96231b3b80d8
