* llmv-objdump/COFF: Print export table contents.Rui Ueyama2014-01-161-3/+95
| | | | | | | | | | | | | | | | This patch adds the capability to dump export table contents. An example output is this: Export Table: Ordinal RVA Name 5 0x2008 exportfn1 6 0x2010 exportfn2 By adding this feature to llvm-objdump, we will be able to use it to check export table contents in LLD's tests. Currently we are doing binary comparison in the tests, which is fragile and not readable to humans. llvm-svn: 199358
* Don't use DataRefImpl to implement ImportDirectoryEntryRef.Rui Ueyama2014-01-161-37/+17
| | | | | | | | | DataRefImpl (a union of two integers and a pointer) is not the ideal data type to represent a reference to an import directory entity. We should just use the pointer to the import table and an offset instead to simplify. No functionality change. llvm-svn: 199349
* Readobj: If NumbersOfSections is 0xffff, it's an COFF import library.Rui Ueyama2013-11-151-4/+7
| | | | | | | | 0xffff does not mean that there are 65535 sections in a COFF file but indicates that it's a COFF import library. This patch fixes SEGV error when an import library file is passed to llvm-readobj. llvm-svn: 194844

* Avoid some getSymbolNMTypeChar uses in COFFObjectFile.cpp itself.Rafael Espindola2013-11-021-12/+6
| | | | | | This is a fixed version of 193928 which keeps these uses in sync. llvm-svn: 193931

* llvm-objdump: Dump COFF import table if -private-headers option is given.Rui Ueyama2013-09-271-30/+166
| | | | | | | | | | | | | | | | This is a patch to add capability to llvm-objdump to dump COFF Import Table entries, so that we can write tests for LLD checking Import Table contents. llvm-objdump did not print anything but just file name if the format is COFF and -private-headers option is given. This is a patch adds capability for dumping DLL Import Table, which is specific to the COFF format. In this patch I defined a new iterator to iterate over import table entries. Also added a few functions to COFFObjectFile.cpp to access fields of the entry. Differential Revision: http://llvm-reviews.chandlerc.com/D1719 llvm-svn: 191472
* Retry submitting r186623: COFFDumper: Dump data directory entries.Rui Ueyama2013-07-191-37/+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
* Revert "COFFDumper: Dump data directory entries."Rui Ueyama2013-07-181-46/+36
| | | | | | Because it broke s390x and ppc64-linux buildbots. This reverts commit r186623. llvm-svn: 186627
* COFFDumper: Dump data directory entries.Rui Ueyama2013-07-181-36/+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.

* readobj: Dump PE/COFF optional records.Rui Ueyama2013-06-121-36/+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
* Handle relocations that don't point to symbols.Rafael Espindola2013-06-051-4/+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
* Change getRelocationAdditionalInfo to be ELF only.Rafael Espindola2013-05-091-5/+0
| | | | | | | It was only implemented for ELF where it collected the Addend, so this patch also renames it to getRelocationAddend. llvm-svn: 181502
* Clarify getRelocationAddress x getRelocationOffset a bit.Rafael Espindola2013-04-251-2/+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
