* Add support for the 's' operation to llvm-ar.Rafael Espindola2013-07-291-2/+6
| | | | | | | | | | | | 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

* Delete the buffer in createObjectFile if it fails.Rafael Espindola2013-07-241-1/+4
| | | | | | | | | | The Binary constructor takes ownership of the memory buffer. This is a fairly unfortunate interface, but for now make createObjectFile consistent with it by also deleting the buffer if it fails. Fixes a leak in llvm-ar found by the valgrind bots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187039 91177308-0d34-0410-b5e6-96231b3b80d8

* 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.

* Change llvm-ar to use lib/Object.Rafael Espindola2013-07-121-26/+23
| | | | | | | | | | | | | | | | | | | | | | 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] Make symbol table top-level key.Sean Silva2013-06-221-7/+3
| | | | | | | | | Although in reality the symbol table in ELF resides in a section, the standard requires that there be no more than one SHT_SYMTAB. To enforce this constraint, it is cleaner to group all the symbols under a top-level `Symbols` key on the object file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184627 91177308-0d34-0410-b5e6-96231b3b80d8
* [yaml2obj][ELF] Don't explicitly set `Binding` with STB_*Sean Silva2013-06-211-10/+7
| | | | | | | | | | | | | | | 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. Also, this new approach is simpler ;) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184506 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the LLVM specific archive index.Rafael Espindola2013-06-141-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Archive files (.a) can have a symbol table indicating which object files in them define which symbols. The purpose of this symbol table is to speed up linking by allowing the linker the read only the .o files it is actually going to use instead of having to parse every object's symbol table. LLVM's archive library currently supports a LLVM specific format for such table. It is hard to see any value in that now that llvm-ld is gone: * System linkers don't use it: GNU ar uses the same plugin as the linker to create archive files with a regular index. The OS X ar creates no symbol table for IL files, I assume the linker just parses all IL files. * It doesn't interact well with archives having both IL and native objects. * We probably don't want to be responsible for yet another archive format variant. This patch then: * Removes support for creating and reading such index from lib/Archive. * Remove llvm-ranlib, since there is nothing left for it to do. We should in the future add support for regular indexes to llvm-ar for both native and IL objects. When we do that, llvm-ranlib should be reimplemented as a symlink to llvm-ar, as it is equivalent to "ar s". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184019 91177308-0d34-0410-b5e6-96231b3b80d8
