* Fix lookup of fields from lazy bindings to check if the region isTed Kremenek2010-02-091-9/+5

* Migrate the mish-mash of declaration checks inDouglas Gregor2010-02-093-177/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Sema::ActOnUninitializedDecl over to InitializationSequence (with default initialization), eliminating redundancy. More importantly, we now check that a const definition in C++ has an initilizer, which was an #if 0'd code for many, many months. A few other tweaks were needed to get everything working again: - Fix all of the places in the testsuite where we defined const objects without initializers (now that we diagnose this issue) - Teach instantiation of static data members to find the previous declaration, so that we build proper redeclaration chains. Previously, we had the redeclaration chain but built it too late to be useful, because... - Teach instantiation of static data member definitions not to try to check an initializer if a previous declaration already had an initializer. This makes sure that we don't complain about static const data members with in-class initializers and out-of-line definitions. - Move all of the incomplete-type checking logic out of Sema::FinalizeDeclaratorGroup; it makes more sense in ActOnUnitializedDecl. There may still be a few places where we can improve these diagnostics. I'll address that as a separate commit. llvm-svn: 95657
* IRgen: Add CreateMemTemp, for creating an temporary memory object for a ↵Daniel Dunbar2010-02-098-49/+51
| | | | | | | | | | particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing. - This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome! PR6240. llvm-svn: 95648

* Pass inline keyword to optimizer as the new InlineHint function attribute.Jakob Stoklund Olesen2010-02-091-0/+10
| | | | | | | | | | At the moment the inlinehint attribute is ignored by the Inliner unless you pass a -respect-inlinehint option. This will soon be the default. The inlinehint attribute is set if the inline keyword is explicitly specified on any declaration. llvm-svn: 95623
