* Add support for the 's' operation to llvm-ar.Rafael Espindola2013-07-292-0/+32
| | | | | | | | | | | | 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. llvm-svn: 187353
* Add an initial implementation of archive symbol table generation.Rafael Espindola2013-07-232-0/+18
| | | | | | | | | | | The symbol table has forward references in the file. Instead of allocating a temporary buffer or counting the size and then writing, this implementation writes a dummy value first and patches it once the final value is known. There is room for performance improvement. I will implement them as soon as I get some other features (like a ranlib mode) in. llvm-svn: 186934
* Mark ELF's first symbol as format specific so that llvm-nm ignores it.Rafael Espindola2013-07-221-0/+1

* Replace archive members in the old position.Rafael Espindola2013-07-221-0/+3
| | | | | | | | | | | | This matches gnu archive behavior and since archive member order can change which member is used, not changing the order on replacement looks like the right thing to do. This patch also refactors the logic for which archive member to keep and whether to move it to a helper function (computeInsertAction). The nesting in computeNewArchiveMembers was getting a bit confusing. llvm-svn: 186829
* Don't depend on a llvm-ar specific behavior.Rafael Espindola2013-07-221-1/+2
| | | | | | | | GNU ar when not given the a or b modifiers replaces archive members in the same location of the old ones. I am about to implement that in llvm-ar. For now, just don't depend on the current llvm-ar behavior on this test. llvm-svn: 186823
* Handle replacement into a position past the original member.Rafael Espindola2013-07-211-0/+13
| | | | | | | We were incorrectly computing where to insert a member if it was replacing a previous member that was before the insert point. llvm-svn: 186792
* Fix inserting new elements in a specified location.Rafael Espindola2013-07-191-0/+13
| | | | | | We were only handling the 'a' and 'b' options during moves before. llvm-svn: 186721
* Split openFileForWrite into windows and unix versions.Rafael Espindola2013-07-191-0/+13
| | | | | | It is similar to 186511, but for creating files for writing. llvm-svn: 186679
* Split openFileForRead into Windows and Unix versions.Rafael Espindola2013-07-171-2/+1
| | | | | | | | | | | This has some advantages: * Lets us use native, utf16 windows functions. * Easy to produce good errors on windows about trying to use a directory when we want a file. * Simplifies the unix version a bit. llvm-svn: 186511

It had been buggy since the initial commit. FIXME: Could we rename {from|to}Win32Time as {from|to}Win32FILETIME in TimeValue? llvm-svn: 186374

* The archive update test has a subtle race condition in it: if the testChandler Carruth2013-07-141-7/+15
| | | | | | | | | | | | | | | | | | is executed within the same second as the inputs for the test are checked out from the source tree, it will fail to update due to being below the resolution of the 'mtime' test used. Now, this may seem improbably to you... ok, maybe *really* improbable, but consider a system which does distributed execution of tests by shipping their inputs to another machine and runs them. That might cause the mtime to be quite recent during the test run. ;] Instead, create two files directly in the test (allowing all platforms to see the problem) and add either a use of the 'touch' command that forces one mtime to some time quite a bit in the past, or it sleeps for just over a second to be outside of the precision window. llvm-svn: 186282

* Change llvm-ar to use lib/Object.Rafael Espindola2013-07-122-3/+5
| | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 186197

| | | | | | | It is not reliable to depend on the output of llvm_unreachable. The original change will have proper tests when llvm-ar moves to lib/Object (soon). llvm-svn: 186043

* Move tests from test/Archive to test/Object.Rafael Espindola2013-07-1015-0/+69
| | | | | | | | There is no lib/Archive anymore and some archive tests were in test/Archive and others in test/Object. Since archive is just one of the formats supported by lib/Object, test/Object is probably the best location. llvm-svn: 186038

* [yaml2obj][ELF] Make symbol table top-level key.Sean Silva2013-06-222-25/+21
| | | | | | | | | 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. llvm-svn: 184627
* This was a nifty test, but remove it.Sean Silva2013-06-211-6/+0
| | | | | | | | | | | | | | It wouldn't really test anything that doesn't already have a more targeted test: `yaml2obj-elf-section-basic.yaml`: Already tests that section content is correctly passed though. `yaml2obj-elf-symbol-basic.yaml` (this file): Tests that the st_value and st_size attributes of `main` are set correctly. Between those two tests, disassembling the file doesn't really add anything, so just remove mention of disassembling the file. llvm-svn: 184607
