Reid Kleckner ed8bca4f42 Make it easier to build against a pre-built Clang package with CMake
Installing <prefix>/share/clang/cmake/ClangConfig.cmake makes CMake's
builtin find_package() utility work with Clang. This also allows
downstream consumers of Clang to statically link against libraries like
clangAST and have that pull in dependencies like clangBasic and
LLVMSupport.

See the CMake docs on packages:

Alexey Samsonov 70f3897b0a [Sanitizer] Introduce generic stack frame rendering machinery
Summary:
This commit introduces function __sanitizer::RenderFrame()
that allows to render the contents of AddressInfo (essentially, symbolized stack frame)
using the custom format string. This function can be used to
implement stack frame formatting for both ThreadSanitizer and
generic StackTrace::Print(), used in another places. This paves the
way towards allowing user to control the format of stack frames,
obtaining them in any format he desires, and/or enforcing the consistent
output from all sanitizers.

Added missing memory folding for the (V)CVTDQ2PS instructions - we can safely fold these (but not the (V)CVTDQ2PD versions which have a register/memory size discrepancy in the source operand). I've added a test case demonstrating that stack folding now works.

Fariborz Jahanian 1839abdabe This patch fixes a crash after rebuilding call AST of
an __unknown_anytype(...). In this case, we rebuild the
vararg function type specially to convert the call expression
to  something that IRGen can handle. However, FunctionDecl
as rebuilt in RebuildUnknownAnyExpr::resolveDecl is bogus and
results in crash when accessing its params later on. This
patch fixes the crash by rebuilding the FunctionDecl to match
its new resolved type. rdar://15297105.

Tobias Grosser 16371acdc4 BlockGenerator: Recompute values from SCEV before handing back the original values
This patch moves the SCEV based (re)generation of values before the checking for
scop-constant terms. It enables us to provide SCEV based replacements, which
are necessary to correctly generate OpenMP subfunctions when using the SCEV
based code generation.

When recomputing a new value for a value used in the code of the original scop,
we previously directly returned the same original value for all scop-constant
expressions without even trying to regenerate these values using our SCEV
expression. This is correct when the newly generated code remains fully in the
same function, however in case we want to outline parts of the newly generated
scop into subfunctions, this approach means we do not have any opportunity to
update these values in the SCEV based code generation. (In the non-SCEV based
code generation, we can provide such updates through the GlobalMap). To ensure
we have this opportunity, we first try to regenerate scalar terms with our SCEV
builder and will only return scop-constant expressions if SCEV based code
generation was not possible.

This change should not affect the results of the existing code generation
passes. It only impacts the upcoming OpenMP based code generation.

This commit also adds a test case. This test case passes before and after this
commit. It was added to ensure test coverage for the changed code.

Frederic Riss b1ab28c949 [DebugInfo] Do not record artificial global initializer functions in the DeclCache.
When we are generating the global initializer functions, we call
CGDebugInfo::EmitFunctionStart() with a valid decl which is describing
the initialized global variable. Do not update the DeclCache with this
key as it will overwrite the the cached variable DIGlobalVariable with
the newly created artificial DISubprogram.

One could wonder if we should put artificial subprograms in the DIE tree
at all (there are vaild uses for them carrying line information though).

Kuba Brecka fe4e7c1716 Fix failing allow_user_segv.cc test on OS X 10.10
The current ASan testcase Posix/allow_user_segv.cc expects SIGBUS to be triggered on 32-bit Darwin. This has apparently changed on 10.10 to trigger SIGSEGV instead, just as on 64-bit. Let's just install handlers for both SIGSEGV and SIGBUS instead of #ifdef'ing.

Justin Holewinski 3d140fcfd1 [NVPTX] Add NVPTXLowerStructArgs pass
This works around the limitation that PTX does not allow .param space
loads/stores with arbitrary pointers.

If a function has a by-val struct ptr arg, say foo(%struct.x *byval %d), then
add the following instructions to the first basic block :

%temp = alloca %struct.x, align 8
%tt1 = bitcast %struct.x * %d to i8 *
%tt2 = llvm.nvvm.cvt.gen.to.param %tt2
%tempd = bitcast i8 addrspace(101) * to %struct.x addrspace(101) *
%tv = load %struct.x addrspace(101) * %tempd
store %struct.x %tv, %struct.x * %temp, align 8

The above code allocates some space in the stack and copies the incoming
struct from param space to local space. Then replace all occurences of %d
by %temp.

Fixes PR21465.

Peter Collingbourne a1099840ff [dfsan] Abort at runtime on indirect calls to uninstrumented vararg functions.
We currently have no infrastructure to support these correctly.

This is accomplished by generating a call to a runtime library function that
aborts at runtime in place of the regular wrapper for such functions. Direct
calls are rewritten in the usual way during traversal of the caller's IR.

We also remove the "split-stack" attribute from such wrappers, as the code
generator cannot currently handle split-stack vararg functions.
