[llvm] Get rid of "%T" expansions The %T lit expansion expands to a common directory shared between all the tests in the same directory, which is unexpected and unintuitive, and more importantly, it's been a source of subtle race conditions and flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it would be best to simply ban %T and only keep %t, which is unique to each test. When a test needs a temporary directory, it can just create one using mkdir %t. This patch removes %T in llvm. Differential Revision: https://reviews.llvm.org/D36495 llvm-svn: 310953

Use std::error_code instead of llvm::error_code. 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++. llvm-svn: 210687

Add r184420 back, but also handle long file names. Original message: Don't include directory names in archives. This matches the behavior of both gnu and os x versions of ar. llvm-svn: 184423

Change llvm-ar to use lib/Object. 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

Use only the filename when deciding if a file is a duplicate. Matches gnu ar behavior. llvm-svn: 184448
