David Blaikie	218b783192	Update Clang tests to handle explicitly typed gep changes in LLVM. ... llvm-svn: 230783	2015-02-27 19:18:17 +00:00
Hal Finkel	a2347baaec	Mark C++ reference parameters as dereferenceable ... Because references must be initialized using some evaluated expression, they must point to something, and a callee can assume the reference parameter is dereferenceable. Taking advantage of a new attribute just added to LLVM, mark them as such. Because dereferenceability in addrspace(0) implies nonnull in the backend, we don't need both attributes. However, we need to know the size of the object to use the dereferenceable attribute, so for incomplete types we still emit only nonnull. llvm-svn: 213386	2014-07-18 15:52:10 +00:00
Nick Lewycky	9b46eb8112	Add 'nonnull' parameter or return attribute when producing an llvm pointer type in a function type where the C++ type is a reference. Update the tests. ... llvm-svn: 209723	2014-05-28 09:56:42 +00:00
Stephen Lin	4362261b00	CHECK-LABEL-ify some code gen tests to improve diagnostic experience when tests fail. ... llvm-svn: 188447	2013-08-15 06:47:53 +00:00
Richard Smith	2bcde3a74c	PR12848: When emitting a local variable declared 'constexpr', always initialize it with a store or a memcpy, not by emitting the initializer expression. This is not required for correctness, but more closely aligns with people's expectations, and is cheap (since we've already evaluated the initializer). ... llvm-svn: 183082	2013-06-02 00:09:52 +00:00
John McCall	a37c2fa409	Fix the emission of the copy-initialization of a block capture ... from a lambda capture when the capture is not trivially-copyable. rdar://13295759 llvm-svn: 176431	2013-03-04 06:32:36 +00:00
John McCall	7133505936	Unify the BlockDeclRefExpr and DeclRefExpr paths so that ... we correctly emit loads of BlockDeclRefExprs even when they don't qualify as ODR-uses. I think I'm adequately convinced that BlockDeclRefExpr can die. llvm-svn: 152479	2012-03-10 03:05:10 +00:00
