2013-07-24Delete the buffer in createObjectFile if it fails.Rafael Espindola1-1/+4
The Binary constructor takes ownership of the memory buffer. This is a fairly unfortunate interface, but for now make createObjectFile consistent with it by also deleting the buffer if it fails. Fixes a leak in llvm-ar found by the valgrind bots. llvm-svn: 187039
2013-06-18Basic support for parsing Mach-O universal binaries in LLVMObject libraryAlexey Samsonov1-0/+1
llvm-svn: 184191
2013-06-11Fix variable name style. Don't cast to and from int.Rafael Espindola1-0/+2
This enables the compiler to see the enum and produce warnings about a switch not being fully covered. Fix one of these warnings. llvm-svn: 183749
2013-06-11Convert another use of sys::identifyFileType.Rafael Espindola1-25/+26
No functionality change. llvm-svn: 183747

2013-05-30Change how we iterate over relocations on ELF.Rafael Espindola1-0/+4
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
2013-04-29Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola1-0/+6
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

2013-01-25When encountering an unknown file format, ObjectFile::createObjectFile shouldEli Bendersky1-1/+3
politely report it instead of running into llvm_unreachable. Also patch llvm-dwarfdump to actually check whether the file it's attempting to dump is a valid object file. llvm-svn: 173489
