* llvm-cov: Support specifying multiple source filesJustin Bogner2014-06-27
| | | | | | | | | Make llvm-cov compatible with gcov for cases where multiple files are specified on the command line. That is, loop over each one and report coverage, and report errors on stderr only rather than via return code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211959 91177308-0d34-0410-b5e6-96231b3b80d8
* [RuntimeDyld] Add a framework for testing relocation logic in RuntimeDyld.Lang Hames2014-06-27
| | | | | | | | | | | | | | | | | | | | | | This patch adds a "-verify" mode to the llvm-rtdyld utility. In verify mode, llvm-rtdyld will test supplied expressions against the linked program images that it creates in memory. This scheme can be used to verify the correctness of the relocation logic applied by RuntimeDyld. The expressions to test will be read out of files passed via the -check option (there may be more than one of these). Expressions to check are extracted from lines of the form: # rtdyld-check: <expression> This system is designed to fit the llvm-lit regression test workflow. It is format and target agnostic, and supports verification of images linked for remote targets. The expression language is defined in llvm/include/llvm/RuntimeDyldChecker.h . Examples can be found in test/ExecutionEngine/RuntimeDyld. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211956 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't force the build of toos/lto as a static lib.Rafael Espindola2014-06-27
| | | | | | | | Any uses of tools/lto as a static lib should probably move to lib/LTO. This was also never implemented in the configure build, so this reduces the differences among the two. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211852 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce a string_ostream string builder faciltyAlp Toker2014-06-26
| | | | | | | | | | | | | | | | | | | | string_ostream is a safe and efficient string builder that combines opaque stack storage with a built-in ostream interface. small_string_ostream<bytes> additionally permits an explicit stack storage size other than the default 128 bytes to be provided. Beyond that, storage is transferred to the heap. This convenient class can be used in most places an std::string+raw_string_ostream pair or SmallString<>+raw_svector_ostream pair would previously have been used, in order to guarantee consistent access without byte truncation. The patch also converts much of LLVM to use the new facility. These changes include several probable bug fixes for truncated output, a programming error that's no longer possible with the new interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211749 91177308-0d34-0410-b5e6-96231b3b80d8

* Pass a unique_ptr<MemoryBuffer> to the constructors in the Binary hierarchy.Rafael Espindola2014-06-24
| | | | | | | Once the objects are constructed, they own the buffer. Passing a unique_ptr makes that clear. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211595 91177308-0d34-0410-b5e6-96231b3b80d8
* Pass a std::unique_ptr& to the create??? methods is lib/Object.Rafael Espindola2014-06-23
| | | | | | | | This makes the buffer ownership on error conditions very natural. The buffer is only moved out of the argument if an object is constructed that now owns the buffer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211546 91177308-0d34-0410-b5e6-96231b3b80d8
* Make ObjectFile and BitcodeReader always own the MemoryBuffer.Rafael Espindola2014-06-23
| | | | | | | | | | This allows us to just use a std::unique_ptr to store the pointer to the buffer. The flip side is that they have to support releasing the buffer back to the caller. Overall this looks like a more efficient and less brittle api. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211542 91177308-0d34-0410-b5e6-96231b3b80d8

* Use lib/LTO directly in the gold plugin.Rafael Espindola2014-06-19
| | | | | | | | | | | | | | | | | | | | The tools/lto API is not the best choice for implementing a gold plugin. Among other issues: * It is an stable ABI. Old errors stay and we have to be really careful before adding new features. * It has to support two fairly different linkers: gold and ld64. * We end up with a plugin that depends on a shared lib, something quiet unusual in LLVM land. * It hides LLVM. For some features in the gold plugin it would be really nice to be able to just get a Module or a GlobalValue. This change is intended to be a very direct translation from the C API. It will just enable other fixes and cleanups. Tested with a LTO bootstrap on linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211315 91177308-0d34-0410-b5e6-96231b3b80d8

Like System V format, there are also some small changes in how and where the file names and archive member names are printed for darwin and Mach-O.

* Finishing touch for the std::error_code transition.Rafael Espindola2014-06-13
| | | | | | | | | | | While std::error_code itself seems to work OK in all platforms, there are few annoying differences with regards to the std::errc enumeration. This patch adds a simple llvm enumeration, which will hopefully avoid build breakages in other platforms and surprises as we get more uses of std::error_code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210920 91177308-0d34-0410-b5e6-96231b3b80d8
* opt: Initialize asm printersTobias Grosser2014-06-13
| | | | | | | | | | | | | | Without initializing the assembly printers a shared library build of opt is linked with these libraries whereas for a static build these libraries are dead code eliminated. This is unfortunate for plugins in case they want to use them, as they neither can rely on opt to provide this functionality nor can they link the printers in themselves as this breaks with a shared object build of opt. This patch calls InitializeAllAsmPrinters() from opt, which increases the static binary size from 50MB -> 52MB on my system (all backends compiled) and causes no measurable increase in the time needed to run 'make check'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210914 91177308-0d34-0410-b5e6-96231b3b80d8

* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea of this patch is to turn llvm/Support/system_error.h into a transitional header that just brings in the erorr_code api to the llvm namespace. I will remove it shortly afterwards. The cases where the general idea needed some tweaking: * std::errc is a namespace in msvc, so we cannot use "using std::errc". I could add an #ifdef, but there were not that many uses, so I just added std:: to them in this patch. * Template specialization had to be moved to the std namespace in this patch set already. * The msvc implementation of default_error_condition doesn't seem to provide the same transformations as we need. Not too surprising since the standard doesn't actually say what "equivalent" means. I fixed the problem by keeping our old mapping and using it at error_code construction time. Despite these shortcomings I think this is still a good thing. Some reasons: * The different implementations of system_error might improve over time. * It removes 925 lines of code from llvm already. * It removes 6313 bytes from the text segment of the clang binary when it is built with gcc and 2816 bytes when building with clang and libstdc++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210687 91177308-0d34-0410-b5e6-96231b3b80d8
