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!

This does not yet implement the LimitNode approach discussed.

2012-11-14Provide the correct mangling and linkage for certain unnamed nested classes.David Blaikie
This corrects the mangling and linkage of classes (& their member functions) in cases like this: struct foo { struct { void func() { ... } } x; }; we were accidentally giving this nested unnamed struct 'no' linkage where it should've had the linkage of the outer class. The mangling was incorrecty too, mangling as TU-wide unnamed type mangling of $_X rather than class-scoped mangling of UtX_. This also fixes -Wunused-member-function which would incorrectly diagnose 'func' as unused due to it having no linkage & thus appearing to be TU-local when in fact it might be correctly used in another TU. Similar mangling should be applied to function local classes in similar cases but I've deferred that for a subsequent patch.

2012-09-10Comment AST: TableGen'ize all command lists in CommentCommandTraits.cpp.Dmitri Gribenko
Now we have a list of all commands. This is a good thing in itself, but it also enables us to easily implement typo correction for command names. With this change we have objects that contain information about each command, so it makes sense to resolve command name just once during lexing (currently we store command names as strings and do a linear search every time some property value is needed). Thus comment token and AST nodes were changed to contain a command ID -- index into a tables of builtin and registered commands. Unknown commands are registered during parsing and thus are also uniformly assigned an ID. Using an ID instead of a StringRef is also a nice memory optimization since ID is a small integer that fits into a common bitfield in Comment class. This change implies that to get any information about a command (even a command name) we need a CommandTraits object to resolve the command ID to CommandInfo*. Currently a fresh temporary CommandTraits object is created whenever it is needed since it does not have any state. But with this change it has state -- new commands can be registered, so a CommandTraits object was added to ASTContext. Also, in libclang CXComment has to be expanded to include a CXTranslationUnit so that all functions working on comment AST nodes can get a CommandTraits object. This breaks binary compatibility of CXComment APIs. Now clang_FullComment_getAsXML(CXTranslationUnit TU, CXComment CXC) doesn't need TU parameter anymore, so it was removed. This is a source-incompatible change for this C API. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163540 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-14Attaching comments to redeclarations: fix wrong assumptionsDmitri Gribenko
The reason for the recent fallout for "attaching comments to any redeclaration" change are two false assumptions: (1) a RawComment is attached to a single decl (not true for 'typedef struct X *Y' where we want the comment to be attached to both X and Y); (2) the whole redeclaration chain has only a single comment (obviously false, the user can put a separate comment for each redeclaration). To fix (1) I revert the part of the recent change where a 'Decl*' member was introduced to RawComment. Now ASTContext has a separate DenseMap for mapping 'Decl*' to 'FullComment*'. To fix (2) I just removed the test with this assumption. We might not parse every comment in redecl chain if we already parsed at least one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161878 91177308-0d34-0410-b5e6-96231b3b80d8
