* 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* COFF: Add back an assertion that is superseded by r222124David Majnemer2014-11-251-1/+1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
* Update llvm-objdump’s Mach-O symbolizer code for Objective-C references.Kevin Enderby2014-10-231-2/+38
| | | | | | | This prints disassembly comments for Objective-C references to CFStrings, Selectors, Classes and method calls. llvm-svn: 220500
* [MCJIT] Temporarily revert r220245 - it broke several bots.Lang Hames2014-10-211-3/+0
| | | | | | (See e.g. http://bb.pgr.jp/builders/cmake-llvm-x86_64-linux/builds/17653) llvm-svn: 220249
* [MCJIT] Make MCJIT honor symbol visibility settings when populating the globalLang Hames2014-10-201-0/+3
| | | | | | | | symbol table. Patch by Anthony Pesch. Thanks Anthony! llvm-svn: 220245
* Be more specific about return type of MachOUniversalBinary::getObjectForArchAlexey Samsonov2014-10-201-2/+2
| | | | llvm-svn: 220230
* [llvm-objdump] Fix mach-o binding decompression errorNick Kledzik2014-10-181-3/+3
| | | | llvm-svn: 220119
* Add MachOObjectFile::getUuid()Alexander Potapenko2014-10-151-1/+10
| | | | | | | This CL introduces MachOObjectFile::getUuid(). This function returns an ArrayRef to the object file's UUID, or an empty ArrayRef if the object file doesn't contain an LC_UUID load command. The new function is gonna be used by llvm-symbolizer. llvm-svn: 219866
* Object, COFF: Move the VirtualSize/SizeOfRawData logic to getSectionSizeDavid Majnemer2014-10-091-18/+23
| | | | | | | | While getSectionContents was updated to do the right thing, getSectionSize wasn't. Move the logic to getSectionSize and leverage it from getSectionContents. llvm-svn: 219391
* Object, COFF: Cap the section contents to min(VirtualSize, SizeOfRawData)David Majnemer2014-10-091-5/+19
| | | | | | | | | | | | | | | | It is not useful to return the data beyond VirtualSize it's less than SizeOfRawData. An implementation detail of COFF requires the section size to be rounded up to a multiple of FileAlignment; this means that SizeOfRawData is not representative of how large the section is. Instead, we should cap it to VirtualSize when this occurs as it represents the true size of the section. Note that this is only relevant in executable files because this rounding doesn't occur in object files (and VirtualSize is always zero). llvm-svn: 219388
* Object: Add range iterators for COFF import/export tableRui Ueyama2014-10-091-0/+26
| | | | llvm-svn: 219383
* Correctly compute the size of common symbols in COFF.Rafael Espindola2014-10-081-4/+9
| | | | llvm-svn: 219324
* Remove bogus std::error_code returns form SectionRef.Rafael Espindola2014-10-083-139/+67
| | | | | | | | | | | | | | There are two methods in SectionRef that can fail: * getName: The index into the string table can be invalid. * getContents: The section might point to invalid contents. Every other method will always succeed and returning and std::error_code just complicates the code. For example, a section can have an invalid alignment, but if we are able to get to the section structure at all and create a SectionRef, we will always be able to read that invalid alignment. llvm-svn: 219314
* Don't check for null after calling COFFObjectFile::toSec.Rafael Espindola2014-10-071-2/+0
| | | | | | | | | | | It can only return null if passed a corrupted reference with a null Ref.p. Checking for null is then an issue for asserts to check for internal consistency, not control flow to check for invalid input. I didn't add an assert(sec != nullptr) because toSec itself has a far more complete assert. llvm-svn: 219235
* Optimize COFFObjectFile::sectionContainsSymbol a bit.Rafael Espindola2014-10-071-7/+2
| | | | | | | | | There is no need to compute the coff_section of the symbol just to compare the pointer. Inspired by the ELF implementation. llvm-svn: 219233
* llvm-readobj: print out the fields of the COFF delay-import tableRui Ueyama2014-10-031-0/+6
| | | | llvm-svn: 218996
* llvm-readobj: print COFF delay-load import tableRui Ueyama2014-10-031-13/+90
| | | | | | | | | This patch adds another iterator to access the delay-load import table and use it from llvm-readobj. http://reviews.llvm.org/D5594 llvm-svn: 218933
* llvm-readobj: print COFF imported symbolsRui Ueyama2014-10-021-0/+90
| | | | | | | | This patch defines a new iterator for the imported symbols. Make a change to COFFDumper to use that iterator to print out imported symbols and its ordinals. llvm-svn: 218915
