| | | | | | | | | | | | | | Summary: This patch introduces ACLE header file, implementing extensions that can be directly mapped to existing Clang intrinsics. It implements for both AArch32 and AArch64.

* 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.

* Fix a bug in my previous patch by restoring the behavior that the fatalChandler Carruth2014-06-27
| | | | | | | | | | | | | | error handler is only registered once. To avoid the use of std::call_once (the obvious way to do this) I've wrapped everything up into a managed static and done the work in a constructor. Silly, but it should be effective. Some out-of-tree libclang users reported this to me, and I've asked them to put together a test case which exhibits this behavior, but I wanted to fix things ASAP since the nature of the fix is straight forward. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211905 91177308-0d34-0410-b5e6-96231b3b80d8

* [ARM] Fix AAPCS non-compliance caused by very large structsOliver Stannard2014-06-27
| | | | | | | | | | | | | | | | This is a fix to the code in clang which inserts padding arguments to ensure that the ARM backend can emit AAPCS-VFP compliant code. This code needs to track the number of registers which have been allocated in order to do this. When passing a very large struct (>64 bytes) by value, clang emits IR which takes a pointer to the struct, but the backend converts this back to passing the struct in registers and on the stack. The bug was that this was being considered by clang to only use one register, meaning that there were situations in which padding arguments were incorrectly emitted by clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211898 91177308-0d34-0410-b5e6-96231b3b80d8

* [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

* Driver: use GNU::Link for the Generic_GCC toolchainSaleem Abdulrasool2014-06-27
| | | | | | | | | | | | | | | | | This changes the behaviour of the driver for linking to match that of the Generic_GCC::Assemble. The default link should use "ld" rather than "gcc" for the linker as gcc does. This avoids the unnecessary round-tripping through gcc. It also is much more reasonable behaviour from the user's perspective. This should have been updated with SVN r195554 which changed the behaviour of Generic_GCC::Assemble. The gcc_forward test needs to be updated to mark the fact that -march is a flag for GCC not ld. This was updated as a typo fix, but added a check for a flag that is not a link flag. The bindings test covers the change for testing, and thus no new test was added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211866 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
