2013-07-19Retry submitting r186623: COFFDumper: Dump data directory entries.Rui Ueyama1-37/+49
The original change was rolled back in r186627 because of test failures on the big endian machine. I believe I fixed the issue so re-submitting. llvm-svn: 186734
2013-07-18Revert "COFFDumper: Dump data directory entries."Rui Ueyama1-46/+36
Because it broke s390x and ppc64-linux buildbots. This reverts commit r186623. llvm-svn: 186627
2013-07-18COFFDumper: Dump data directory entries.Rui Ueyama1-36/+46
Summary: Dump optional data directory entries in the PE/COFF header, so that we can test the output of LLD linker. This patch updates the test binary file, but the source of the binary is the same. I just re-linked the file. I don't know how the previous file was linked, but the previous file did not have any data directory entries for some reason.

2013-06-12readobj: Dump PE/COFF optional records.Rui Ueyama1-36/+63
These records are mandatory for executables and are used by the loader. Reviewers: rafael CC: llvm-commits Differential Revision: http://llvm-reviews.chandlerc.com/D939 llvm-svn: 183852
2013-06-05Handle relocations that don't point to symbols.Rafael Espindola1-4/+2
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
2013-05-09Change getRelocationAdditionalInfo to be ELF only.Rafael Espindola1-5/+0
It was only implemented for ELF where it collected the Addend, so this patch also renames it to getRelocationAddend. llvm-svn: 181502
2013-04-25Clarify getRelocationAddress x getRelocationOffset a bit.Rafael Espindola1-2/+1
getRelocationAddress is for dynamic libraries and executables, getRelocationOffset for relocatable objects. Mark the getRelocationAddress of COFF and MachO as not implemented yet. Add a test of ELF's. llvm-readobj -r now prints the same values as readelf -r. llvm-svn: 180259

Add ObjectFile::getLoadName() for retrieving the soname/installname of a shared object. llvm-svn: 151845
2012-03-01[Object]David Meyer1-0/+20
* Add begin_dynamic_table() / end_dynamic_table() private interface to ELFObjectFile. * Add begin_libraries_needed() / end_libraries_needed() interface to ObjectFile, for grabbing the list of needed libraries for a shared object or dynamic executable. * Implement this new interface completely for ELF, leave stubs for COFF and MachO. * Add 'llvm-readobj' tool for dumping ObjectFile information. llvm-svn: 151785
2012-02-29[Object] Add symbol attribute flags: ST_ThreadLocal, ST_Common, and ↵David Meyer1-2/+6
ST_Undefined. Implement these completely for ELF. Rename ST_External to ST_Unknown, and slightly change its semantics. It now only indicates that the symbol's type is unknown, not that the symbol is undefined. (For that, use ST_Undefined). llvm-svn: 151696
2012-02-28In the ObjectFile interface, replace isInternal(), isAbsolute(), isGlobal(), ↵David Meyer1-22/+15

2011-09-14Object: make the following changes into SymbolRefBenjamin Kramer1-1/+50
- Add enum SymbolType and function getSymbolType() - Add function isGlobal() - it's returns true for symbols that can be used in another objects, such as library functions. - Rename function getAddress() to getOffset() and add new function getAddress(), because currently getAddress() returns section offset of symbol first byte. new getAddress() return symbol address. - Change usage SymbolRef::getAddress() to getOffset() in tools/llvm-nm and tools/llvm-objdump.
