* Implement a new 'availability' attribute, that allows one to specifyDouglas Gregor2011-03-231-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 128127
* Add support for language-specific address spaces. On top of that,Peter Collingbourne2011-03-181-0/+6
| | | | | | | | | add support for the OpenCL __private, __local, __constant and __global address spaces, as well as the __read_only, _read_write and __write_only image access specifiers. Patch originally by ARM; language-specific address space support by myself. llvm-svn: 127915

* PowerPC fixes.Roman Divacky2011-01-061-0/+1
| | | | | | | | | | | | | Fix the width and align of bool type on Darwin to be 32bits while keeping it 8 everywhere else. Change the definition of va_list to default to SV4 ABI one and let darwin subtarget override this. Both changes submitted by Nathan Whitehorn and reviewed by Rafael Espindola. llvm-svn: 122956

* Add TargetInfo::useBitfieldTypeAlignment().Daniel Dunbar2010-04-151-3/+3
| | | | | | | | | | | | | | | - Used to determine whether the alignment of the type in a bit-field is respected when laying out structures. The default is true, targets can override this as needed. - This is designed to correspond to the PCC_BITFIELD_TYPE_MATTERS macro in gcc. The AST/Sema implementation only affects one line, unless I have forgotten something. I'd appreciate further review. - IRgen still needs to be updated to fully support this (which is effectively PR5591). llvm-svn: 101356
