2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-13Add a per target max vector alignment field (e.g., 32-byte alignment for x86 ↵Chad Rosier
due to AVX). Currently, if no aligned attribute is specified the alignment of a vector is inferred from its size. Thus, very large vectors will be over-aligned with no benefit.

2011-08-04Add partial support for using anonymous bitfields (e.g., int : 0) to enforce Chad Rosier

2011-03-23Implement a new 'availability' attribute, that allows one to specifyDouglas Gregor
which versions of an OS provide a certain facility. For example, void foo() __attribute__((availability(macosx,introduced=10.2,deprecated=10.4,obsoleted=10.6))); says that the function "foo" was introduced in 10.2, deprecated in 10.4, and completely obsoleted in 10.6. This attribute ties in with the deployment targets (e.g., -mmacosx-version-min=10.1 specifies that we want to deploy back to Mac OS X 10.1). There are several concrete behaviors that this attribute enables, as illustrated with the function foo() above: - If we choose a deployment target >= Mac OS X 10.4, uses of "foo" will result in a deprecation warning, as if we had placed attribute((deprecated)) on it (but with a better diagnostic) - If we choose a deployment target >= Mac OS X 10.6, uses of "foo" will result in an "unavailable" warning (in C)/error (in C++), as if we had placed attribute((unavailable)) on it - If we choose a deployment target prior to 10.2, foo() is weak-imported (if it is a kind of entity that can be weak imported), as if we had placed the weak_import attribute on it. Naturally, there can be multiple availability attributes on a declaration, for different platforms; only the current platform matters when checking availability attributes. The only platforms this attribute currently works for are "ios" and "macosx", since we already have -mxxxx-version-min flags for them and we have experience there with macro tricks translating down to the deprecated/unavailable/weak_import attributes. The end goal is to open this up to other platforms, and even extension to other "platforms" that are really libraries (say, through a #pragma clang define_system), but that hasn't yet been designed and we may want to shake out more issues with this narrower problem first. Addresses <rdar://problem/6690412>. As a drive-by bug-fix, if an entity is both deprecated and unavailable, we only emit the "unavailable" diagnostic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128127 91177308-0d34-0410-b5e6-96231b3b80d8
