| | | | | | | | | | | | | | | | | struct may cause it to shrink more than one byte. Before my recent changes we compiled the new test into: %0 = type { [6 x i8] } @x = global %0 { [6 x i8] undef }, align 2 ; <%0*> [#uses=0] which is obviously bogus. Now we compile it into: %0 = type <{ i32, i8, i8 }> @x = global %0 zeroinitializer, align 2 ; <%0*> [#uses=0] Where the last byte only is tail padding. llvm-svn: 101536

| | | | | | | | | | | | | | | | | | | | | | | | elements with explicit zero values instead of with tail padding. On an example like this: struct foo { int a; int b; }; struct foo fooarray[] = { {1, 2}, {4}, }; We now lay this out as: @fooarray = global [2 x %struct.foo] [%struct.foo { i32 1, i32 2 }, %struct.foo { i32 4, i32 0 }] instead of as: @fooarray = global %0 <{ %struct.foo { i32 1, i32 2 }, %1 { i32 4, [4 x i8] zeroinitializer } }> Preserving both the struct type of the second element, but also the array type of the entire thing. llvm-svn: 101155

* Numerous changes to selector handling:David Chisnall2010-02-031-0/+8
| | | | | | | | | | | | | | | | | | | | | | | - Don't use GlobalAliases with non-0 GEPs (GNU runtime) - this was unsupported and LLVM will be generating errors if you do it soon. This also simplifies the code generated by the GNU runtime a bit. - Make GetSelector() return a constant (GNU runtime), not a load of a store of a constant. - Recognise @selector() expressions as valid static initialisers (as GCC does). - Add methods to GCObjCRuntime to emit selectors as constants (needed for using @selector() expressions as constants. These need implementing for the Mac runtimes - I couldn't figure out how to do this, they seem to require a load. - Store an ObjCMethodDecl in an ObjCSelectorExpr so that we can get at the type information for the selector. This is needed for generating typed selectors from @selector() expressions (as GCC does). Ideally, this information should be stored in the Selector, but that would be an invasive change. We should eventually add checks for common uses of @selector() expressions. Possibly adding an attribute that can be applied to method args providing the types of a selector so, for example, you'd do something like this: - (id)performSelector: __attribute__((selector_types(id, SEL, id)))(SEL) withObject: (id)object; Then, any @selector() expressions passed to the method will be check to ensure that it conforms to this signature. We do this at run time on the GNU runtime already, but it would be nice to do it at compile time on all runtimes. - Made @selector() expressions emit type info if available and the runtime supports it. Someone more familiar with the Mac runtime needs to implement the GetConstantSelector() function in CGObjCMac. This currently just assert()s. llvm-svn: 95189

* Eliminate QualifiedDeclRefExpr, which captured the notion of aDouglas Gregor2009-10-231-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | qualified reference to a declaration that is not a non-static data member or non-static member function, e.g., namespace N { int i; } int j = N::i; Instead, extend DeclRefExpr to optionally store the qualifier. Most clients won't see or care about the difference (since QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the number of top-level expression types that clients need to cope with, brings the implementation of DeclRefExpr into line with MemberExpr, and simplifies and unifies our handling of declaration references. Extended DeclRefExpr to (optionally) store explicitly-specified template arguments. This occurs when naming a declaration via a template-id (which will be stored in a TemplateIdRefExpr) that, following template argument deduction and (possibly) overload resolution, is replaced with a DeclRefExpr that refers to a template specialization but maintains the template arguments as written. llvm-svn: 84962

| | | | | | | | | | which is a common idiom to improve PIC'ness of code using the addr of label extension. This implementation is a gross hack, but the only other alternative would be to teach evalutate about this horrid combination. While GCC allows things like "&&foo - &&bar + 1", people don't use this in practice. This implements PR5131. llvm-svn: 83957
