* Remove 'const' from MemoryBuffers used through the SourceManagerDavid Blaikie2014-06-27
| | | | | | | | | | | | | | This removes a const_cast added in r211884 that occurred due to an inconsistency in how MemoryBuffers are handled between some parts of clang and LLVM. MemoryBuffers are immutable and the general convention in the LLVM project is to omit const from immutable types as it's simply redundant/verbose (see llvm::Type, for example). While this change doesn't remove "const" from /every/ MemoryBuffer, it at least makes this chain of ownership/usage consistent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211915 91177308-0d34-0410-b5e6-96231b3b80d8
* clang-cl: Map /EHs- to -fno-exceptionsReid Kleckner2014-06-27
| | | | | | | | | | | | | | | This isn't 100% compatible with MSVC, but it's close enough. MSVC's /EH flag doesn't really control exceptions so much as how to clean up after an exception is thrown. The upshot is that cl.exe /EHs- will compile try, throw, and catch statements with a warning, but clang-cl will reject such constructs with a hard error. We can't compile such EH constructs anyway, but this may matter to consumers of the AST.

* [ARM-BE] Generate correct NEON intrinsics for big endian systems.James Molloy2014-06-27
| | | | | | | | | | | | | The NEON intrinsics in arm_neon.h are designed to work on vectors "as-if" loaded by (V)LDR. We load vectors "as-if" (V)LD1, so the intrinsics are currently incorrect. This patch adds big-endian versions of the intrinsics that does the "obvious but dumb" thing of reversing all vector inputs and all vector outputs. This will produce extra REVs, but we trust the optimizer to remove them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211893 91177308-0d34-0410-b5e6-96231b3b80d8

* Do not inline methods of C++ containers (coming from headers).Anna Zaks2014-06-27
| | | | | | | | | | | | | | | | | | | This silences false positives (leaks, use of uninitialized value) in simple code that uses containers such as std::vector and std::list. The analyzer cannot reason about the internal invariances of those data structures which leads to false positives. Until we come up with a better solution to that problem, let's just not inline the methods of the containers and allow objects to escape whenever such methods are called. This just extends an already existing flag "c++-container-inlining" and applies the heuristic not only to constructors and destructors of the containers, but to all of their methods. We have a bunch of distinct user reports all related to this issue (radar://16058651, radar://16580751, radar://16384286, radar://16795491 [PR19637]). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211832 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement the -fuse-ld= option.Logan Chien2014-06-26
| | | | | | | | | | | | | | | This commit implements the -fuse-ld= option, so that the user can specify -fuse-ld=bfd to use ld.bfd. This commit re-applies r194328 with some test case changes. It seems that r194328 was breaking macosx or mingw build because clang can't find ld.bfd or ld.gold in the given sysroot. We should use -B to specify the executable search path instead.

* MS ABI: Propagate class-level DLL attributes to class template ↵Hans Wennborg2014-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | specialization bases (PR11170) Consider the following code: template <typename T> class Base {}; class __declspec(dllexport) class Derived : public Base<int> {} When the base of an exported or imported class is a class template specialization, MSVC will propagate the dll attribute to the base. In the example code, Base<int> becomes a dllexported class. This commit makes Clang do the proopagation when the base hasn't been instantiated yet, and warns about it being unsupported otherwise. This is different from MSVC, which allows changing a specialization back and forth between dllimport and dllexport and seems to let the last one win. Changing the dll attribute after instantiation would be hard for us, and doesn't seem to come up in practice, so I think this is a reasonable limitation to have. MinGW doesn't do this kind of propagation. Differential Revision: http://reviews.llvm.org/D4264 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211725 91177308-0d34-0410-b5e6-96231b3b80d8

There are cases though that some APIs don't care about user methods and such warnings are perceived as noise. This patch allows users to add paren delimiters around selector name to turn off such warnings. So, @selector((save:)) will turn off the warning.

* Add new debug kind LocTrackingOnly.Diego Novillo2014-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This new debug emission kind supports emitting line location information in all instructions, but stops code generation from emitting debug info to the final output. This mode is useful when the backend wants to track source locations during code generation, but it does not want to produce debug info. This is currently used by optimization remarks (-Rpass, -Rpass-missed and -Rpass-analysis). When one of the -Rpass flags is used, the front end will enable location tracking, only if no other debug option is enabled. To prevent debug information from being generated, a new debug info kind LocTrackingOnly causes DIBuilder::createCompileUnit() to not emit the llvm.dbg.cu annotation. This blocks final code generation from generating debug info in the back end. Depends on D4234.
