* AArch64: add support for llvm.aarch64.hint intrinsicSaleem Abdulrasool2014-07-123-11/+89
| | | | | | | | | | | This adds a llvm.aarch64.hint intrinsic to mirror the llvm.arm.hint in order to support the various hint intrinsic functions in the ACLE. Add an optional pattern field that permits the subclass to specify the pattern that matches the selection. The intrinsic pattern is set as mayLoad, mayStore, so overload the value for the definition of the hint instruction. llvm-svn: 212883
* MC: remove use of unnecessary variableSaleem Abdulrasool2014-07-121-41/+27
| | | | | | | | | Due to the fact that the windows unwinding has the concept of chained frames, we maintain a current frame info pointer that is adjusted on any push and pop of a unwinding context. This just removes an unnecessary variable that was used to mirror the DWARF unwinding code. llvm-svn: 212882
* MC: rename MCW64UnwindInfo to MCWinFrameInfoSaleem Abdulrasool2014-07-125-31/+31
| | | | | | | | This structure contains information related to the call frame used to generate unwinding information. Rename this to reflect the future use to represent the shared state between various architectures for WinCFI information. llvm-svn: 212881

* llgs: modify to accept --native-regs flag.Todd Fiala2014-07-121-10/+13
| | | | | | | | | | | | | | | | This is the last flag sent by lldb-platform that was not accepted by llgs and is accepted by debugserver. Conditionalized out a bit more code in prep for Windows support one day based on _WIN32 define. Updated the lldb-gdbserver usage string to represent recent updates to command line arguments (and some older ones like --attach pid). Implements https://github.com/tfiala/lldb/issues/37 llvm-svn: 212879
* Add FreeBSD failure decorator for TestCallStopAndContinueEd Maste2014-07-121-0/+1
| | | | | | | | | | The testrun now completes successfully on my FreeBSD 11.0-CURRENT laptop. There are some intermittent failures on the FreeBSD buildbot still, which should be addressed in later commits. llvm.org/pr20274 llvm-svn: 212878

* Fix an issue with the MergeBasicBlockIntoOnlyPred() helper function where it didOwen Anderson2014-07-122-5/+5
| | | | | | | | | | not properly handle the case where the predecessor block was the entry block to the function. The only in-tree client of this is JumpThreading, which worked around the issue in its own code. This patch moves the solution into the helper so that JumpThreading (and other clients) do not have to replicate the same fix everywhere. llvm-svn: 212875
* Add nonnull in CodeGen for __attribute__((returns_nonnull))Hal Finkel2014-07-122-0/+8
| | | | | | | As a follow-up to r212835, also add the LLVM nonnull function attribute when __attribute__((returns_nonnull)) is provided. llvm-svn: 212874
* llgs: implement --setsid.Todd Fiala2014-07-123-4/+115
| | | | | | | | | | | | | The --setsid (-S) option changes the session id for the lldb-gdbserver process. This is used by tools such as lldb-platform and allows the user to prevent llgs from being in the same session as a calling terminal session. This will prevents terminal group control signals from affecting lldb-gdbserver. See also: https://github.com/tfiala/lldb/issues/38 llvm-svn: 212873
* [ASan] Collect unmangled names of global variables in Clang to print them in ↵Alexey Samsonov2014-07-129-47/+86
| | | | | | | | | | | | | | | | | error reports. Currently ASan instrumentation pass creates a string with global name for each instrumented global (to include global names in the error report). Global name is already mangled at this point, and we may not be able to demangle it at runtime (e.g. there is no __cxa_demangle on Android). Instead, create a string with fully qualified global name in Clang, and pass it to ASan instrumentation pass in llvm.asan.globals metadata. If there is no metadata for some global, ASan will use the original algorithm. This fixes https://code.google.com/p/address-sanitizer/issues/detail?id=264. llvm-svn: 212872

* clang-cl: Make all x86 CPU feature flags available, such as -msse3Reid Kleckner2014-07-122-3/+5
| | | | | | | | | | | | | Ideally, we would use the /arch cl.exe flag for this stuff. Unfortunately, MSVC supports only 5 /arch flag values, which isn't nearly enough to cover all the CPU features that LLVM cares about. At the very least, we need to know about SSE3 and SSE4.1 in addition to SSE, SSE2, AVX, and AVX2. In the future we should add the relevant /arch mappings in addition to these gcc-style -m flags. llvm-svn: 212869

* BFI: Clean up BlockMassDuncan P. N. Exon Smith2014-07-122-45/+22
| | | | | | | | | | | | | | Implementation is small now -- the interesting logic was moved to `BranchProbability` a while ago. Move it into `bfi_detail` and get rid of the related TODOs. I was originally planning to define it within `BlockFrequencyInfoImpl` (or `BFIIBase`), but it seems cleaner in a namespace. Besides, `isPodLike` needs to be specialized before `BlockMass` can be used in some of the other data structures, and there isn't a clear way to do that. llvm-svn: 212866

For example structure return demotion and non-simple types are not supported (yet). Currently every backend has its own implementation and duplicated code for call lowering. There is also no specified interface that could be called from target-independent code. The target-hook is opt-in and doesn't affect current implementations. llvm-svn: 212848

* Add the "-s" flag to llvm-nm for Mach-O files that prints symbols only inKevin Enderby2014-07-112-0/+78

This option takes exactly two strings and should be allowed anywhere on the command line. Such that "llvm-nm -s __TEXT __text foo.o" would work. But that does not as the CommandLine Library does not have a way to make this work as far as I can tell. For now the "-s __TEXT __text" has to be last on the command line. llvm-svn: 212842
* CodeGen: Don't emit a thread-wrapper if we can't touch the backing variableDavid Majnemer2014-07-112-9/+48
| | | | | | | | | | | | | | | | OS X TLS has all accesses going through the thread-wrapper function and gives the backing thread-local variable internal linkage. This means that thread-wrappers must have WeakAnyLinkage so that references to the internal thread-local variables do not get propagated to other code. It also means that translation units which do not provide a definition for the thread-local variable cannot attempt to emit a thread-wrapper because the thread wrapper will attempt to reference the backing variable.
