* CodeGen: Improve warnings about uninstrumented files when profilingJustin Bogner2014-06-26
| | | | | | | | | Improve the warning when building with -fprofile-instr-use and a file appears not to have been profiled at all. This keys on whether a function is defined in the main file or not to avoid false negatives when one includes a header with functions that have been profiled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211760 91177308-0d34-0410-b5e6-96231b3b80d8

* CodeGen: Correct linkage of thread_local for OS XDavid Majnemer2014-06-11
| | | | | | | | | | | | | The backing store of thread local variables is internal for OS X and all accesses must go through the thread wrapper. However, individual TUs may have inlined through the thread wrapper. To fix this, give the thread wrapper functions WeakAnyLinkage. This prevents them from getting inlined into call-sites. This fixes PR19989. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@210632 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement -Wframe-larger-than backend diagnosticAlp Toker2014-06-05
| | | | | | | | | | | | | | | | | | Add driver and frontend support for the GCC -Wframe-larger-than=bytes warning. This is the first GCC-compatible backend diagnostic built around LLVM's reporting feature. This commit adds infrastructure to perform reverse lookup from mangled names emitted after LLVM IR generation. We use that to resolve precise locations and originating AST functions, lambdas or block declarations to produce seamless codegen-guided diagnostics. An associated change, StringMap now maintains unique mangled name strings instead of allocating copies. This is a net memory saving in C++ and a small hit for C where we no longer reuse IdentifierInfo storage, pending further optimisation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@210293 91177308-0d34-0410-b5e6-96231b3b80d8

* Refactor and generalize GetAddrOfConstantString and ↵Alexey Samsonov2014-06-04
| | | | | | | | | | | | | | GetAddrOfConstantStringFromLiteral. Share mode code between these functions and re-structure them in a way which shows how similar they actually are. The latter function works well with literals of multi-byte chars and does a GlobalVariable name mangling (if global strings are non-writable).

* [ASan] Hoist blacklisting globals from init-order checking to Clang.Alexey Samsonov2014-05-29
| | | | | | | | | | Clang knows about the sanitizer blacklist and it makes no sense to add global to the list of llvm.asan.dynamically_initialized_globals if it will be blacklisted in the instrumentation pass anyway. Instead, we should do as much blacklisting as possible (if not all) in the frontend. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@209789 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't dllimport/export destructor variants implemented by thunks.Hans Wennborg2014-05-28
| | | | | | | | | | | | MSVC doesn't export these functions, so trying to import them doesnt' work. Also, don't let any dll attributes on the CXXDestructorDecl influence the thunk's linkage -- they should always be linkonce_odr. This takes care of the FIXME's for this in Nico's tests.

* Use comdats to avoid double initialization of weak dataReid Kleckner2014-05-23
| | | | | | | | | | | | | | | | | Initializers of global data that can appear multiple TUs (static data members of class templates or __declspec(selectany) data) are now in a comdat group keyed on the global variable being initialized. On non-Windows platforms, this is a code size and startup time optimization. On Windows, this is necessary for ABI compatibility with MSVC. Fixes PR16959.

* Don't set unnamed_addr in CreateRuntimeVariable.Rafael Espindola2014-05-22
| | | | | | | | | | | | | This was fairly broken. For example, @__dso_handle would or would not get an unnamed_addr depending on how many global destructors were used in a translation unit. The consensus was that not every runtime variable is unnamed_addr and that __dso_handle handle should not be, so just don't add unnamed_addr in CreateRuntimeVariable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@209484 91177308-0d34-0410-b5e6-96231b3b80d8

* Update for llvm api change.Rafael Espindola2014-05-16
| | | | | | | | | | Now that llvm cannot represent alias cycles, we have to diagnose erros just before trying to close the cycle. This degrades the errors a bit. The real solution is what it was before: if we want to provide good errors for these cases, we have to be able to find a clang level decl given a mangled name and produce the error from Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@209008 91177308-0d34-0410-b5e6-96231b3b80d8

* Disable this-return optimizations when targeting iOS 5 and earlier.Bob Wilson2014-04-01
| | | | | | | | | | | | | | | | Clang implements the part of the ARM ABI saying that certain functions (e.g., constructors and destructors) return "this", but Apple's version of gcc and llvm-gcc did not. The libstdc++ dylib on iOS 5 was built with llvm-gcc, which means that clang cannot safely assume that code from the C++ runtime will correctly follow the ABI. It is also possible to run into this problem when linking with other libraries built with gcc or llvm-gcc. Even though there is no way to reliably detect that situation, it is most likely to come up when targeting older versions of iOS. Disabling the optimization for any code targeting iOS 5 solves the libstdc++ problem and has a reasonably good chance of fixing the issue for other older libraries as well. <rdar://problem/16377159> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@205272 91177308-0d34-0410-b5e6-96231b3b80d8
