* Undef'ing _WIN32_IE to silence an MSVC warning about redefining a macro value.Aaron Ballman2014-02-03
| | | | | | No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200704 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. This in turn allows a lot of simplification of APIs by not coding them against a specific small size which is rarely needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200687 91177308-0d34-0410-b5e6-96231b3b80d8

* 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.

* Roll back the ConstStringRef change for nowAlp Toker2014-01-27
| | | | | | | | | | | There are a couple of interesting things here that we want to check over (particularly the expecting asserts in StringRef) and get right for general use in ADT so hold back on this one. For clang we have a workable templated solution to use in the meanwhile. This reverts commit r200187. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200194 91177308-0d34-0410-b5e6-96231b3b80d8
* 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

| | | | | | | | | | | | This moves the ARM build attributes definitions and support routines into the Support library.

The movement is prompted in order to permit access to the constants and string representations from readobj in order to facilitate decoding of the attributes section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199575 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

* Make sys::ThreadLocal<> zero-initialized on non-thread builds (PR18205)Hans Wennborg2013-12-19
| | | | | | | | | | | | | According to the docs, ThreadLocal<>::get() should return NULL if no object has been set. This patch makes that the case also for non-thread builds and adds a very basic unit test to check it. (This was causing PR18205 because PrettyStackTraceHead didn't get zero- initialized and we'd crash trying to read past the end of that list. We didn't notice this so much on Linux since we'd crash after printing all the entries, but on Mac we print into a SmallString, and would crash before printing that.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197718 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
