| | | | | | -private-headers. llvm-svn: 224534
* Add printing the LC_LINKER_OPTION load command with llvm-objdump’s ↵Kevin Enderby2014-12-181-3/+3
| | | | | | | | | | -private-headers. Also corrected the name of the load command to not end in an ’S’ as well as corrected the name of the MachO::linker_option_command struct and other places that had the word option as plural which did not match the Mac OS X headers. llvm-svn: 224485
* Add printing the LC_ENCRYPTION_INFO_64 load command with llvm-objdump’s ↵Kevin Enderby2014-12-171-0/+5
| | | | | | | | -private-headers and add tests for the two AArch64 binaries. llvm-svn: 224400

| | | | | | -private-headers. llvm-svn: 224390
* Start adding thin archive support.Rafael Espindola2014-12-161-3/+17
| | | | | | This is just sufficient for 'ar t' to work. llvm-svn: 224307
* Silence more static analyzer warnings.Michael Ilseman2014-12-151-0/+2
| | | | | | | | Add in definedness checks for shift operators, null checks when pointers are assumed by the code to be non-null, and explicit unreachables. llvm-svn: 224255
* Move three methods only used by MCJIT to MCJIT.Rafael Espindola2014-12-102-49/+6
| | | | | | | | These methods are only used by MCJIT and are very specific to it. In fact, they are also fairly specific to the fact that we have a dynamic linker of relocatable objects. llvm-svn: 223964
* Return ErrorOr<std::unique_ptr<Archive>> form getAsArchive.Rafael Espindola2014-12-091-14/+10
| | | | | | This is the same return type of Archive::create. llvm-svn: 223827
* Rename createIRObjectFile to just create.Rafael Espindola2014-12-092-4/+4
| | | | | | | It is a static method of IRObjectFile, so having to use IRObjectFile::createIRObjectFile was redundant. llvm-svn: 223822
* Move method out of line to make buildbot happy.Rafael Espindola2014-12-091-0/+2
| | | | llvm-svn: 223781
* Don't lookup an object symbol name in the module.Rafael Espindola2014-12-091-5/+2
| | | | | | | | | | | Instead, walk the obj symbol list in parallel to find the GV. This shouldn't change anything on ELF where global symbols are not mangled, but it is a step toward supporting other object formats. Gold itself is ELF only, but bfd ld supports COFF and the logic in the gold plugin could be reused on lld. llvm-svn: 223780
* Add mach-o LC_RPATH support to llvm-objdumpJean-Daniel Dupas2014-12-041-0/+5
| | | | | | | | | | Summary: Add rpath load command support in Mach-O object and update llvm-objdump to use it. Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D6512 llvm-svn: 223343
* Add ARM relocations to ELFYAMLWill Newton2014-12-021-0/+3
| | | | | | Tested with check-all with no regressions. llvm-svn: 223112
* Object/COFF: Fix off-by-one error for object having lots of relocationsRui Ueyama2014-11-261-1/+2
| | | | | | | | | llvm-objdump printed out an error message for this off-by-one error, but because it always exits with 0 whether or not it found an error, the test (llvm-objdump/coff-many-relocs.test) succeeded. I made llvm-objdump exit with EXIT_FAILURE when an error is found. llvm-svn: 222852
* COFF: Add back an assertion that is superseded by r222124David Majnemer2014-11-251-1/+1
| | | | llvm-svn: 222735
* Remove duplication of relocation names in lib/Object/ELFYAML.cppTim Northover2014-11-211-330/+7
| | | | | | | | | | We can now use the ELF relocation .def files to create the mapping of relocation numbers to names and avoid having to duplicate the list of relocations. Patch by Will Newton. llvm-svn: 222567
* Remove duplication of relocation names in lib/Object/ELF.cppTim Northover2014-11-211-742/+14
| | | | | | | | | | We can now use the ELF relocation .def files to create the mapping of relocation numbers to names and avoid having to duplicate the list of relocations. Patch by Will Newton. llvm-svn: 222566
* llvm-readobj: fix off-by-one error in COFFDumperRui Ueyama2014-11-191-1/+1
| | | | | | | | It printed out base relocation table header as table entry. This patch also makes llvm-readobj to not skip ABSOLUTE entries becuase it was confusing. llvm-svn: 222299
* llvm-readobj: teach it how to dump COFF base relocation tableRui Ueyama2014-11-191-1/+69
| | | | llvm-svn: 222289
* Support ELF files of unknown type.Michael J. Spencer2014-11-183-0/+3
| | | | llvm-svn: 222208
* Object, COFF: Tighten the object file parserDavid Majnemer2014-11-171-27/+47
| | | | | | | | | | | | We were a little lax in a few areas: - We pretended that import libraries were like any old COFF file, they are not. In fact, they aren't really COFF files at all, we should probably grow some specialized functionality to handle them smarter. - Our symbol iterators were more than happy to attempt to go past the end of the symbol table if you had a symbol with a bad list of auxiliary symbols. llvm-svn: 222124
* obj2yaml, yaml2obj: Add support for COFF executablesDavid Majnemer2014-11-142-5/+115
| | | | | | | | | | | | | | | | In support of serializing executables, obj2yaml now records the virtual address and size of sections. It also serializes whatever we strictly need from the PE header, it expects that it can reconstitute everything else via inference. yaml2obj can reconstitute a fully linked executable. In order to get executables correctly serialized/deserialized, other bugs were fixed as a circumstance. We now properly respect file and section alignments. We also avoid writing out string tables unless they are strictly necessary. llvm-svn: 221975
* Un-break the big-endian buildbotsRui Ueyama2014-11-131-2/+2
| | | | llvm-svn: 221919
* Object, Mach-O: Refactor and clean code upDavid Majnemer2014-11-131-12/+25
| | | | | | | Don't assert if we can return an error code, reuse existing functionality like is64Bit(). llvm-svn: 221915
* Object, COFF: Refactor code to get relocation iteratorsDavid Majnemer2014-11-131-26/+24
| | | | | | No functional change intended. llvm-svn: 221880
* Object, COFF: Increase code reuseDavid Majnemer2014-11-131-24/+32
| | | | | | | | | | Split getObject's smarts into checkOffset, use this to replace the handwritten check in getSectionContents. Similarly, replace checks in section_rel_begin/section_rel_end with getNumberOfRelocations. No functionality change intended. llvm-svn: 221873
* Object, COFF: getRelocationSymbol shouldn't assertDavid Majnemer2014-11-131-1/+1
| | | | | | | | lib/Object is supposed to be robust to malformed object files. Don't assert if we don't have a symbol table. I'll try to come up with a test case later. llvm-svn: 221870
* Object, COFF: Cleanup some code in getSectionNameDavid Majnemer2014-11-131-2/+2
| | | | | | | Use StringRef::startswith to tidy up some code, no functionality change intended. llvm-svn: 221869
* Object, COFF: Fix some theoretical bugsDavid Majnemer2014-11-131-3/+14
| | | | | | | | getObject didn't consider the case where a pointer came before the start of the object file. No test is included, trying to come up with something reasonable. llvm-svn: 221868
* llvm-readobj: Print out address table when dumping COFF delay-import tableRui Ueyama2014-11-131-0/+14
| | | | llvm-svn: 221855
* Object, support both mach-o archive t.o.c file namesNick Kledzik2014-11-121-1/+1
| | | | | | | | | | For historical reasons archives on mach-o have two possible names for the file containing the table of contents for the archive: "__.SYMDEF SORTED" and "__.SYMDEF". But the libObject archive reader only supported the former. This patch fixes llvm::object::Archive to support both names. llvm-svn: 221747
* [yaml2obj] Support AArch64 relocations.Chad Rosier2014-11-101-0/+86
| | | | | | | Patch by Daniel Stewart <stewartd@codeaurora.org>! Phabricator Revision: http://reviews.llvm.org/D6192 llvm-svn: 221639
* [ELF][yaml2obj] Handle additional MIPS specific st_other field flagsSimon Atanasyan2014-11-061-1/+37
| | | | | | | | The ELF symbol `st_other` field might contain additional flags besides visibility ones. This patch implements support for some MIPS specific flags. llvm-svn: 221491
* Object, COFF: Don't consider AuxFunctionDefinition for getSymbolSizeDavid Majnemer2014-11-061-10/+0
| | | | | | | mingw lies about the size of a function's AuxFunctionDefinition. Ignore the field and rely on our heuristic to determine the symbol's size. llvm-svn: 221485
* Object, COFF: Infer symbol sizes from adjacent symbolsDavid Majnemer2014-11-061-7/+39
| | | | | | | | | Use the position of the subsequent symbol in the object file to infer the size of it's predecessor. I hope to eventually remove whatever COFF specific details from this little algorithm so that we can unify this logic with what Mach-O does. llvm-svn: 221444
* llvm-readobj: Add support for dumping the DOS header in PE filesDavid Majnemer2014-11-051-13/+13
| | | | llvm-svn: 221333
* [yaml2obj] Allow yaml2obj tool to recognize EF_MIPS_NAN2008 flagSimon Atanasyan2014-11-041-0/+1
| | | | llvm-svn: 221268
* Remove the static version of getScatteredRelocationType() now that r221211 addedKevin Enderby2014-11-041-5/+0
| | | | | | | | a public version MachOObjectFile::getScatteredRelocationType(). This should fix the build bot for the unused function error. llvm-svn: 221216
* Add the code and test cases for 32-bit Intel to llvm-objdump’s Mach-O ↵Kevin Enderby2014-11-041-0/+5
| | | | | | symbolizer. llvm-svn: 221211
* Object, COFF: Cleanup symbol type code, improve binutils compatibilityDavid Majnemer2014-10-311-44/+75
| | | | | | | Do a better job classifying symbols. This increases the consistency between the COFF handling code and the ELF side of things. llvm-svn: 220952
* Fix unicode chars into ascii in comment lines.NAKAMURA Takumi2014-10-271-1/+1
| | | | llvm-svn: 220668
* Don't ever call materializeAllPermanently during LTO.Rafael Espindola2014-10-241-11/+1
| | | | | | | | | | To do this, change the representation of lazy loaded functions. The previous representation cannot differentiate between a function whose body has been removed and one whose body hasn't been read from the .bc file. That means that in order to drop a function, the entire body had to be read. llvm-svn: 220580
* [Object] Fix MachO's getUuid to return a pointer into the object instead of ↵Benjamin Kramer2014-10-241-2/+3
| | | | | | | | | a dangling ArrayRef. This works because uuid's are always little endian so it's not swapped. Fixes use-after-return reported by asan. llvm-svn: 220567
