2014-04-25Introduce an Emscripten C++ ABI.Dan Gohman
Emscripten uses the Itanium C++ ABI for most things, except that it uses ARM C++ ABI pointers to member functions, to avoid the overhead of aligning functions.
2013-05-06Grab-bag of bit-field fixes:John McCall
- References to ObjC bit-field ivars are bit-field lvalues; fixes rdar://13794269, which got me started down this. - Introduce Expr::refersToBitField, switch a couple users to it where semantically important, and comment the difference between this and the existing API. - Discourage Expr::getBitField by making it a bit longer and less general-sounding. - Lock down on const_casts of bit-field gl-values until we hear back from the committee as to whether they're allowed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181252 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-06Add SystemZ supportUlrich Weigand
This patch then adds all the usual platform-specific pieces for SystemZ: driver support, basic target info, register names and constraints, ABI info and vararg support. It also adds new tests to verify pre-defined macros and inline asm, and updates a test for the minimum alignment change. This version of the patch incorporates feedback from reviews by Eric Christopher and John McCall. Thanks to all reviewers! Patch by Richard Sandiford. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181211 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-06Allow targets to define minimum alignment for global variablesUlrich Weigand
This patch adds a new common code feature that allows platform code to request minimum alignment of global symbols. The background for this is that on SystemZ, the most efficient way to load addresses of global symbol is the LOAD ADDRESS RELATIVE LONG (LARL) instruction. This instruction provides PC-relative addressing, but only to *even* addresses. For this reason, existing compilers will guarantee that global symbols are always aligned to at least 2. [ Since symbols would otherwise already use a default alignment based on their type, this will usually only affect global objects of character type or character arrays. ] GCC also allows creating symbols without that extra alignment by using explicit "aligned" attributes (which then need to be used on both definition and each use of the symbol). To enable support for this with Clang, this patch adds a TargetInfo::MinGlobalAlign variable that provides a global minimum for the alignment of every global object (unless overridden via explicit alignment attribute), and adds code to respect this setting. Within this patch, no platform actually sets the value to anything but the default 1, resulting in no change in behaviour on any existing target. This version of the patch incorporates feedback from reviews by Eric Christopher and John McCall. Thanks to all reviewers!

2013-05-03Support __wchar_t in -fms-extensions and -fms-compatibility modes.Hans Wennborg
MSVC provides __wchar_t, either as an alias for the built-in wchar_t type, or as a separate type depending on language (C vs C++) and flags (-fno-wchar). In -fms-extensions, Clang will simply accept __wchar_t as an alias for whatever type is used for wide character literals. In -fms-compatibility, we try to mimic MSVC's behavior by always making __wchar_t a builtin type. This fixes PR15815. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181004 91177308-0d34-0410-b5e6-96231b3b80d8

Summary: This also relaxes the requirement on Windows that the member pointer class type be a complete type (http://llvm.org/PR12070). We still ask for a complete type to instantiate any templates (MSVC does this), but if that fails we continue as normal, relying on any inheritance attributes on the declaration.

2013-01-16Rework the traversal of Objective-C categories and extensions toDouglas Gregor
consider (sub)module visibility. The bulk of this change replaces myriad hand-rolled loops over the linked list of Objective-C categories/extensions attached to an interface declaration with loops using one of the four new category iterator kinds: visible_categories_iterator: Iterates over all visible categories and extensions, hiding any that have their "hidden" bit set. This is by far the most commonly used iterator. known_categories_iterator: Iterates over all categories and extensions, ignoring the "hidden" bit. This tends to be used for redeclaration-like traversals. visible_extensions_iterator: Iterates over all visible extensions, hiding any that have their "hidden" bit set. known_extensions_iterator: Iterates over all extensions, whether they are visible to normal name lookup or not. The effect of this change is that any uses of the visible_ iterators will respect module-import visibility. See the new tests for examples. Note that the old accessors for categories and extensions are gone; there are *Raw() forms for some of them, for those (few) areas of the compiler that have to manipulate the linked list of categories directly. This is generally discouraged. Part two of <rdar://problem/10634711>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172665 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-12Disable caching of visibility.Rafael Espindola
The testcase in pr14929 shows that this is extremely hard to do. If we choose to apply the attribute, that causes the visibility of some decls to change and that can happen really late (during codegen). Current gcc warns and ignores the attribute in this testcase with a warning. This suggest that the correct solution is to find a point in the compilation where we can compute the visibility and * assert it was never computed before * reject any attempts to compute it again in the future (with warnings). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172305 91177308-0d34-0410-b5e6-96231b3b80d8
