* Readobj: If NumbersOfSections is 0xffff, it's an COFF import library.Rui Ueyama2013-11-15
| | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194844 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-objdump: Dump COFF import table if -private-headers option is given.Rui Ueyama2013-09-27
| | | | | | | | | | | | | | | | 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.

* Explicitly request unsigned enum types when desiredReid Kleckner2013-09-23
| | | | | | | | | | | | | | | | | | | | | The underlying type of all plain enums in MSVC is 'int', even if the enumerator contains large 32-bit unsigned values or values greater than UINT_MAX. The only way to get a large or unsigned enum type is to request it explicitly with the C++11 strong enum types feature. However, since LLVM isn't C++11 yet, I had to add a conditional LLVM_ENUM_INT_TYPE to Compiler.h to control its usage. The motivating true positive for this change is compiling PointerIntPair with MSVC for win64. The PointerIntMask value is supposed to be pointer sized value of all ones with some low zeros. Instead, it's truncated to 32-bits! We are only saved later because it is sign extended back in the AND with int64_t, and we happen to want all ones. This silences lots of -Wmicrosoft warnings during a clang self-host targeting Windows. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191241 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for the 's' operation to llvm-ar.Rafael Espindola2013-07-29
| | | | | | | | | | | | If no other operation is specified, 's' becomes an operation instead of an modifier. The s operation just creates a symbol table. It is the same as running ranlib. We assume the archive was created by a sane ar (like llvm-ar or gnu ar) and if the symbol table is present, then it is current. We use that to optimize the most common case: a broken build system that thinks it has to run ranlib. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187353 91177308-0d34-0410-b5e6-96231b3b80d8
* [PowerPC] Support powerpc64le as a syntax-checking target.Bill Schmidt2013-07-26
| | | | | | | | | | | | | | | | | | | | | | | | This patch provides basic support for powerpc64le as an LLVM target. However, use of this target will not actually generate little-endian code. Instead, use of the target will cause the correct little-endian built-in defines to be generated, so that code that tests for __LITTLE_ENDIAN__, for example, will be correctly parsed for syntax-only testing. Code generation will otherwise be the same as powerpc64 (big-endian), for now. The patch leaves open the possibility of creating a little-endian PowerPC64 back end, but there is no immediate intent to create such a thing. The LLVM portions of this patch simply add ppc64le coverage everywhere that ppc64 coverage currently exists. There is nothing of any import worth testing until such time as little-endian code generation is implemented. In the corresponding Clang patch, there is a new test case variant to ensure that correct built-in defines for little-endian code are generated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187179 91177308-0d34-0410-b5e6-96231b3b80d8
* [mips] Use pristine object file while processing relocations.Akira Hatanaka2013-07-24
| | | | | | | | | | | | | | | | | | | | | Similar to ARM change r182800, dynamic linker will read bits/addends from the original object rather than from the object that might have been patched previously. For the purpose of relocations for MCJIT stubs on MIPS, we internally use otherwise unused MIPS relocations. The change also enables MCJIT unit tests for MIPS (EL/BE), and the following two tests now pass: - MCJITTest.return_global and - MCJITTest.multiple_functions. These issues have been tracked as Bug 16250. Patch by Petar Jovanovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187019 91177308-0d34-0410-b5e6-96231b3b80d8

* COFFDumper: Dump data directory entries.Rui Ueyama2013-07-18
| | | | | | | | | | | | | | | | | 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.

* Change llvm-ar to use lib/Object.Rafael Espindola2013-07-12
| | | | | | | | | | | | | | | | | | | | | | This fixes two bugs is lib/Object that the use in llvm-ar found: * In OS X created archives, the name can be padded with nulls. Strip them. * In the constructor, remember the first non special member and use that in begin_children. This makes sure we skip all special members, not just the first one. The change to llvm-ar itself consist of * Using lib/Object for reading archives instead of ArchiveReader.cpp. * Writing the modified archive directly, instead of creating an in memory representation. The old Archive library was way more general than what is needed, as can be seen by the diffstat of this patch. Having llvm-ar using lib/Object now opens the way for creating regular symbol tables for both native objects and bitcode files so that we can use those archives for LTO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186197 91177308-0d34-0410-b5e6-96231b3b80d8

* [yaml2obj][ELF] Don't explicitly set `Binding` with STB_*Sean Silva2013-06-21
| | | | | | | | | | | | | | | Instead, just have 3 sub-lists, one for each of {STB_LOCAL,STB_GLOBAL,STB_WEAK}. This allows us to be a lot more explicit w.r.t. the symbol ordering in the object file, because if we allowed explicitly setting the STB_* `Binding` key for the symbol, then we might have ended up having to shuffle STB_LOCAL symbols to the front of the list, which is likely to cause confusion and potential for error.
