* Create llvm.global_ctors in the new format.Rafael Espindola2015-12-061-2/+2

* [asan] Rename the ABI versioning symbol to '__asan_version_mismatch_check' ↵Kuba Brecka2015-07-231-1/+9
| | | | | | | | | | instead of abusing '__asan_init' We currently version `__asan_init` and when the ABI version doesn't match, the linker gives a `undefined reference to '__asan_init_v5'` message. From this, it might not be obvious that it's actually a version mismatch error. This patch makes the error message much clearer by changing the name of the undefined symbol to be `__asan_version_mismatch_check_xxx` (followed by the version string). We obviously don't want the initializer to be named like that, so it's a separate symbol that is used only for the purpose of version checking.

* Implement `createSanitizerCtor`, common helper function for all sanitizersIsmail Pazarbasi2015-05-061-0/+21
| | | | | | | | | | | | | | | | | Summary: This helper function creates a ctor function, which calls sanitizer's init function with given arguments. This constructor is then expected to be added to module's ctors. The patch helps unifying how sanitizer constructor functions are created, and how init functions are called across all sanitizers.

* Add comdat key field to llvm.global_ctors and llvm.global_dtorsReid Kleckner2014-05-161-8/+21
| | | | | | | | | | | | | | This allows us to put dynamic initializers for weak data into the same comdat group as the data being initialized. This is necessary for MSVC ABI compatibility. Once we have comdats for guard variables, we can use the combination to help GlobalOpt fire more often for weak data with guarded initialization on other platforms.

* Respect llvm.used in Internalize.Rafael Espindola2013-07-251-0/+18
| | | | | | | | | | | | | | | The language reference says that: "If a symbol appears in the @llvm.used list, then the compiler, assembler, and linker are required to treat the symbol as if there is a reference to the symbol that it cannot see" Since even the linker cannot see the reference, we must assume that the reference can be using the symbol table. For example, a user can add __attribute__((used)) to a debug helper function like dump and use it from a debugger. llvm-svn: 187103
* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-4/+4
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. llvm-svn: 171366
* Move llvm/Support/IRBuilder.h -> llvm/IRBuilder.hChandler Carruth2012-06-291-1/+1
| | | | | | | | | | | | | | | | | This was always part of the VMCore library out of necessity -- it deals entirely in the IR. The .cpp file in fact was already part of the VMCore library. This is just a mechanical move. I've tried to go through and re-apply the coding standard's preferred header sort, but at 40-ish files, I may have gotten some wrong. Please let me know if so. I'll be committing the corresponding updates to Clang and Polly, and Duncan has DragonEgg. Thanks to Bill and Eric for giving the green light for this bit of cleanup. llvm-svn: 159421
