* Use mkdir instead of stat+mkdir.Rafael Espindola2014-02-13
| | | | | | | | | | | | | This is an optimistic version of create_diretories: it tries to create the directory first and looks at the parent only if that fails. Running strace on "mkdir -p" shows that it is pessimistic, calling mkdir on every element of the path. We could implement that if needed. In any case, with both strategies there is no reason to call stat, just check the return of mkdir. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201347 91177308-0d34-0410-b5e6-96231b3b80d8

* Windows/Path.inc: Move <shlobj.h> after "Windows.h" for some API available.NAKAMURA Takumi2014-02-12
| | | | | | | | | | | | | | | I found that swapping the order of some header files helped fix a build issue that we're seeing on mingw32. Without the swap, windows.h was being included before _WIN32_WINNT was being defined and the CreateHardLinkW function was #ifdef'd out. It looks like the header is mainly used to get the SHGetFolderPathW function, so I don't think that there'll be much fallout from the switch. Suggested by Alex Crichton. Thanks! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201230 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix an invalid check for duplicate option categories.Alexander Kornienko2014-02-05
| | | | | | | | | | | | | | | | | | | | Summary: The check performed in the comparator is invalid, as some STL implementations enforce strict weak ordering by calling the comparator with the same value. This check was also in a wrong place: the assertion would only fire when -help was used. The new check is performed each time the category is registered (we are not going to have thousands of them, so it's fine to do it in O(N^2)).

* Fix configure to find arc4random via header files.Todd Fiala2014-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ISSUE: On Ubuntu 12.04 LTS, arc4random is provided by libbsd.so, which is a transitive dependency of libedit. If a system had libedit on it that was implemented in terms of libbsd.so, then the arc4random test, previously implemented as a linker test, would succeed with -ledit. However, on Ubuntu this would also require a #include <bsd/stdlib.h>. This caused a build breakage on configure-based Ubuntu 12.04 with libedit installed. FIX: This fix changes configure to test for arc4random by searching for it in the standard header files. On Ubuntu 12.04, this test now properly fails to find arc4random as it is not defined in the default header locations. It also tweaks the #define names to match the output of the header check command, which is slightly different than the linker function check #defines. I tested the following scenarios: (1) Ubuntu 12.04 without the libedit package [did not find arc4random, as expected] (2) Ubuntu 12.04 with libedit package [properly did not find arc4random, as expected] (3) Ubuntu 12.04 with most recent libedit, custom built, and not dependent on libbsd.so [properly did not find arc4random, as expected]. (4) FreeBSD 10.0B1 [properly found arc4random, as expected] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200819 91177308-0d34-0410-b5e6-96231b3b80d8

* Rename the non-templated base class of SmallPtrSet toChandler Carruth2014-02-03
| | | | | | | | | | | 'SmallPtrSetImplBase'. This more closely matches the organization of SmallVector and should allow introducing a SmallPtrSetImpl which serves the same purpose as SmallVectorImpl: isolating the element type from the particular small size chosen.

* Remove unnecessary call to pthread_mutexattr_setpshared()Mark Seaborn2014-01-29
| | | | | | | | | | | | | | | | | | | The default value of this attribute is PTHREAD_PROCESS_PRIVATE, so there's no point in calling pthread_mutexattr_setpshared() to set that. See: http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_mutexattr_getpshared.html This removes some ifdefs that tend to need to be extended for other platforms (e.g. for NaCl). Note that this call was in the first implementation of Mutex, added in r22403, so it doesn't appear to have been added in response to a performance problem.

* StringRef: Extend constexpr capabilities and introduce ConstStringRefAlp Toker2014-01-27
| | | | | | | | | | | | | | | | | | | (1) Add llvm_expect(), an asserting macro that can be evaluated as a constexpr expression as well as a runtime assert or compiler hint in release builds. This technique can be used to construct functions that are both unevaluated and compiled depending on usage. (2) Update StringRef using llvm_expect() to preserve runtime assertions while extending the same checks to static asserts in C++11 builds that support the feature. (3) Introduce ConstStringRef, a strong subclass of StringRef that references compile-time constant strings. It's convertible to, but not from, ordinary StringRef and thus can be used to add compile-time safety to various interfaces in LLVM and clang that only accept fixed inputs such as diagnostic format strings that tend to get misused. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200187 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce a simple line-by-line iterator type into the Support library.Chandler Carruth2013-12-27
| | | | | | | | | | | | | | | | | | | This is an iterator which you can build around a MemoryBuffer. It will iterate through the non-empty, non-comment lines of the buffer as a forward iterator. It should be small and reasonably fast (although it could be made much faster if anyone cares, I don't really...). This will be used to more simply support the text-based sample profile file format, and is largely based on the original patch by Diego. I've re-worked the style of it and separated it from the work of producing a MemoryBuffer from a file which both simplifies the interface and makes it easier to test. The style of the API follows the C++ standard naming conventions to fit in better with iterators in general, much like the Path and FileSystem interfaces follow standard-based naming conventions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198068 91177308-0d34-0410-b5e6-96231b3b80d8

* Add warning capabilities in LLVM.Quentin Colombet2013-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds a new LLVMContext::diagnose that can be used to communicate to the front-end, if any, that something of interest happened. The diagnostics are supported by a new abstraction, the DiagnosticInfo class. The base class contains the following information: - The kind of the report: What this is about. - The severity of the report: How bad this is. This patch also adds 2 classes: - DiagnosticInfoInlineAsm: For inline asm reporting. Basically, this diagnostic will be used to switch to the new diagnostic API for LLVMContext::emitError. - DiagnosticStackSize: For stack size reporting. Comes as a replacement of the hard coded warning in PEI. This patch also features dynamic diagnostic identifiers. In other words plugins can use this infrastructure for their own diagnostics (for more details, see getNextAvailablePluginDiagnosticKind). This patch introduces a new DiagnosticHandlerTy and a new DiagnosticContext in the LLVMContext that should be set by the front-end to be able to map these diagnostics in its own system. http://llvm-reviews.chandlerc.com/D2376 <rdar://problem/15515174> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197438 91177308-0d34-0410-b5e6-96231b3b80d8
