2014-10-17Add a test that would have found the bug in r219829.Rafael Espindola1-1/+2
llvm-svn: 220016
2014-10-17Revert commit r219835 and r219829.Rafael Espindola1-2/+1
Revert "Correctly handle references to section symbols." Revert "Allow forward references to section symbols." Rui found a regression I am debugging. llvm-svn: 220010
2014-10-15Correctly handle references to section symbols.Rafael Espindola1-1/+2
When processing assembly like .long .text we were creating a new undefined symbol .text. GAS on the other hand would handle that as a reference to the .text section. This patch implements that by creating the section symbols earlier so that they are visible during asm parsing. The patch also updates llvm-readobj to print the symbol number in the relocation dump so that the test can differentiate between two sections with the same name. llvm-svn: 219829
2014-09-26Object: BSS/virtual sections don't have contentsDavid Majnemer1-1/+1
Users of getSectionContents shouldn't try to pass in BSS or virtual sections. In all instances, this is a bug in the code calling this routine. N.B. Some COFF implementations (like CL) will mark their BSS sections as taking space on disk. This would confuse COFFObjectFile into thinking the section is larger than the file. llvm-svn: 218549

2014-03-25Create .symtab_shndxr only when needed.Rafael Espindola1-2/+4
We need .symtab_shndxr if and only if a symbol references a section with an index >= 0xff00. The old code was trying to figure out if the section was needed ahead of time, making it a fairly dependent on the code actually writing the table. It was also somewhat conservative and would create the section in cases where it was not needed. If I remember correctly, the old structure was there so that the sections were created in the same order gas creates them. That was valuable when MC's support for ELF was new and we tested with elf-dump.py. This patch refactors the symbol table creation to another class and makes it obvious that .symtab_shndxr is really only created when we are about to output a reference to a section index >= 0xff00. While here, also improve the tests to use macros. One file is one section short of needing .symtab_shndxr, the second one has just the right number. llvm-svn: 204769

class. llvm-svn: 203345
2014-03-06Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles1-4/+3
This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. llvm-svn: 203083
2014-03-02Switch all uses of LLVM_OVERRIDE to just use 'override' directly.Craig Topper1-12/+12

2014-01-30tools: remove unnecessary typenameSaleem Abdulrasool1-2/+2
This is acceptted by clang and gcc, but MSVC seems to balk at it. As it is unneeded, simply drop it. Fixes MSVC buildbots. llvm-svn: 200456
2014-01-30tools: add support for decoding ARM attributesSaleem Abdulrasool1-0/+44
Enhance the ARM specific parsing support in llvm-readobj to support attributes. This allows for simpler tests to validate encoding of the build attributes as specified in the ARM ELF specification. llvm-svn: 200450

2014-01-08llvm-readobj: add support for ARM EHABI unwind infoSaleem Abdulrasool1-0/+13
This adds some preliminary support for decoding ARM EHABI unwinding information. The major functionality that remains from complete support is bytecode translation. Each Unwind Index Table is printed out as a separate entity along with its section index, name, offset, and entries. Each entry lists the function address, and if possible, the name, of the function to which it corresponds. The encoding model, personality routine or index, and byte code is also listed. llvm-svn: 198734

* ELFTypes.h contains template magic for defining types based on endianess, size, and alignment. * ELFFile.h defines the ELFFile class which provides low level ELF specific access. * ELFObjectFile.h contains ELFObjectFile which uses ELFFile to implement the ObjectFile interface. llvm-svn: 188022

2013-06-05Handle relocations that don't point to symbols.Rafael Espindola1-3/+3
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 Espindola1-4/+4
It was only implemented for ELF where it collected the Addend, so this patch also renames it to getRelocationAddend. llvm-svn: 181502

llvm-svn: 181079
2013-05-03Add support for reading ARM ELF build attributes.Amara Emerson1-0/+63
Build attribute sections can now be read if they exist via ELFObjectFile, and the llvm-readobj tool has been extended with an option to dump this information if requested. Regression tests are also included which exercise these features. Also update the docs with a fixed ARM ABI link and a new link to the Addenda which provides the build attributes specification. llvm-svn: 181009
2013-04-25Clarify getRelocationAddress x getRelocationOffset a bit.Rafael Espindola1-1/+5
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

2013-04-03Implements low-level object file format specific output for COFF andEric Christopher1-0/+800
ELF with support for: - File headers - Section headers + data - Relocations - Symbols - Unwind data (only COFF/Win64) The output format follows a few rules: - Values are almost always output one per line (as elf-dump/coff-dump already do). - Many values are translated to something readable (like enum names), with the raw value in parentheses. - Hex numbers are output in uppercase, prefixed with "0x". - Flags are sorted alphabetically. - Lists and groups are always delimited. Example output: ---------- snip ---------- Sections [ Section { Index: 1 Name: .text (5) Type: SHT_PROGBITS (0x1) Flags [ (0x6) SHF_ALLOC (0x2) SHF_EXECINSTR (0x4) ] Address: 0x0 Offset: 0x40 Size: 33 Link: 0 Info: 0 AddressAlignment: 16 EntrySize: 0 Relocations [ 0x6 R_386_32 .rodata.str1.1 0x0 0xB R_386_PC32 puts 0x0 0x12 R_386_32 .rodata.str1.1 0x0 0x17 R_386_PC32 puts 0x0 ] SectionData ( 0000: 83EC04C7 04240000 0000E8FC FFFFFFC7 |.....$..........| 0010: 04240600 0000E8FC FFFFFF31 C083C404 |.$.........1....| 0020: C3 |.| ) } ] ---------- snip ---------- Relocations and symbols can be output standalone or together with the section header as displayed in the example. This feature set supports all tests in test/MC/COFF and test/MC/ELF (and I suspect all additional tests using elf-dump), making elf-dump and coff-dump deprecated.
