* Add a LLVM_DUMP_METHOD macro.Nico Weber2014-01-03
| | | | | | | | | | | | | | | | The motivation is to mark dump methods as used in debug builds so that they can be called from lldb, but to not do so in release builds so that they can be dead-stripped. There's lots of potential follow-up work suggested in the thread "Should dump methods be LLVM_ATTRIBUTE_USED only in debug builds?" on cfe-dev, but everyone seems to agreen on this subset. Macro name chosen by fair coin toss. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198456 91177308-0d34-0410-b5e6-96231b3b80d8

* Compiler.h: Disable initializer list usage with clang-clReid Kleckner2013-12-05
| | | | | | | | | Most people are using MSVC 2012, which lacks the <initializer_list> header. MSVC 2013 shipped with that header, but it has not yet been tested. If clang works with the 2013 header, then we can enable this by checking the value of _MSC_VER. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196448 91177308-0d34-0410-b5e6-96231b3b80d8

* Explicitly request unsigned enum types when desiredReid Kleckner2013-09-23
| | | | | | | | | | | | | | | | | | | | | The underlying type of all plain enums in MSVC is 'int', even if the enumerator contains large 32-bit unsigned values or values greater than UINT_MAX. The only way to get a large or unsigned enum type is to request it explicitly with the C++11 strong enum types feature. However, since LLVM isn't C++11 yet, I had to add a conditional LLVM_ENUM_INT_TYPE to Compiler.h to control its usage. The motivating true positive for this change is compiling PointerIntPair with MSVC for win64. The PointerIntMask value is supposed to be pointer sized value of all ones with some low zeros. Instead, it's truncated to 32-bits! We are only saved later because it is sign extended back in the AND with int64_t, and we happen to want all ones. This silences lots of -Wmicrosoft warnings during a clang self-host targeting Windows. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191241 91177308-0d34-0410-b5e6-96231b3b80d8

* Reland "Use Clang's __has_* macros in Compiler.h ..." with fixesReid Kleckner2013-07-08
| | | | | | | | | | | | | | | This reverts r185841 and relands r185831 without using __has_attribute(const). Clang prior to r161767 (between 3.1 and 3.2) does not accept __has_attribute(const) due to rdar://10253857. __const and __const__ are both keyword aliases of const, so they don't work either. I was able to repro the buildbot failure using clang 3.1 and this patch fixes it. Various important versions of XCode use clang 2.9-ish, so this workaround is necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185850 91177308-0d34-0410-b5e6-96231b3b80d8

* Attempt to fix Compiler.h for some self-hosting botsReid Kleckner2013-07-08
| | | | | | | I tested r185831 by self-hosting clang with a recent clang, and got no warnings. I haven't been able to reproduce the problem locally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185833 91177308-0d34-0410-b5e6-96231b3b80d8
* Use Clang's __has_* macros in Compiler.h to test for featuresReid Kleckner2013-07-08
| | | | | | | | | | | | | | | | | | When targetting Windows, clang does not define __GNUC__, and as a result we don't use our attributes with it. This leads to warnings about unused functions that are already annotated with LLVM_ATTRIBUTE_UNUSED. Rather than testing for __clang__, we can use its __has_attribute and __has_builtin macros directlty. While I'm here, conditionally define and use __GNUC_PREREQ for gcc version checks. Spelling the check out with three comparisons is verbose and error prone.
