NAKAMURA Takumi b5bb1e2fc6 [CMake] Enable loadable modules, aka plugins, with BUILD_SHARED_LIBS on cygming.
Loadable modules could be enabled without BUILD_SHARED_LIBS with tweaks in future.

David Majnemer b2615aa44d MS ABI: Stick internal vftables in a comdat if they have RTTI data
Previously, we would have a private backing variable and an internal
alias pointing at it.

However, -fdata-sections only fires if a global variable has non-private
linkage.  This means that an unreferenced vftable wouldn't get
discarded, bloating the object file.

Instead, stick the backing variable in a comdat even if the alias has
internal linkage.  This will allow the linker to drop the vftable if it
is unused.

David Majnemer ebc741168b IR: Allow comdats to be applied to globals with internal linkage
Our verifier check for checking if a global has local linkage was too
strict.  Forbid private linkage but permit local linkage.

Object file formats permit this and forbidding it prevents elimination
of unused, internal, vftables under the MSVC ABI.

David Majnemer 299674e94f MC: Let non-temporary COFF aliases be in symtab
MC was aping a binutils bug where aliases would default their linkage to
private instead of internal.

I've sent a patch to the binutils maintainers and they've recently
applied it to the GNU assembler sources.

This fixes PR20152.

Saleem Abdulrasool f74d48a011 AArch64: add support for llvm.aarch64.hint intrinsic
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.

Saleem Abdulrasool db514056de MC: remove use of unnecessary variable
Due to the fact that the windows unwinding has the concept of chained frames, we

Owen Anderson a8d1c3e74e Fix an issue with the MergeBasicBlockIntoOnlyPred() helper function where it did
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.

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.

Alexey Samsonov 15c9669615 [ASan] Collect unmangled names of global variables in Clang to print them in 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.

Reid Kleckner 681ae92083 clang-cl: Make all x86 CPU feature flags available, such as -msse3
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.

Duncan P. N. Exon Smith 345c287da9 BFI: Clean up BlockMass
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.
