* [TLS on Darwin] use CXX_FAST_TLS calling convention for tls_init.Manman Ren2016-03-181-2/+4
| | | | | | | | | | | This makes sure we don't generate a lot of code to spill/reload CSRs when calling tls_init from the access functions. This helps performance when tls_init is not inlined into the access functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@263854 91177308-0d34-0410-b5e6-96231b3b80d8
* [CodeGen] Attach attributes to thread local wrapper function.Akira Hatanaka2016-01-151-3/+4
| | | | | | | | | | | This commit is a follow-up to r251734, r251476, and r249735, which fixes a bug where function attributes were not attached to thread local wrapper functions. rdar://problem/20828324 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@257865 91177308-0d34-0410-b5e6-96231b3b80d8

* [TLS on Darwin] change how we handle globals with linkonce or weak linkage.Manman Ren2015-11-111-4/+8
| | | | | | | | | | | | | This is about how we handle static member of a template. Before this commit, we use internal linkage for the IR thread-local variable, which is inefficient. With this commit, we will start to follow Itanium C++ ABI. rdar://problem/23415206 Reviewed by John McCall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@252814 91177308-0d34-0410-b5e6-96231b3b80d8

* Mark C++ reference parameters as dereferenceableHal Finkel2014-07-181-2/+2
| | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@213386 91177308-0d34-0410-b5e6-96231b3b80d8
