This patch introduces the -fwhole-program-vtables flag, which enables the
whole-program vtable optimization feature (D16795) in Clang.

The add_dependencies call on compiler-rt-configure adds llvm-config and clang to the phony target, but not to the actual configure custom command. We need the dependency bound to the custom command so that it can't be re-ordered by Ninja.

When passing around CMake arguments as lists of arguments any arguments containing lists need to have their semi-colons escaped otherwise CMake will split the arguments in the middle.

This allows COMPILER_RT_* variables to be passed from the top-level CMake into the external project when LLVM_BUILD_EXTERNAL_COMPILER_RT=On.
llvm-svn: 252809
The required compiler-rt changes aren't present yet so attempting to
build with compiler-rt breaks. And since we're trying to deprecate
autotools we actually want to fix this in CMake primarily anyway.
This reverts r251712.
llvm-svn: 251953
This change makes LLVM_BUILD_EXTERNAL_COMPILER_RT work correctly when overriding CMAKE_INSTALL_PREFIX on the install action (which is how LLVM_CREATE_XCODE_TOOLCHAIN works).
This fix is two parts:
(1) Pass CMAKE_INSTALL_PREFIX in as a variable from the parent install to the child install
(2) When passing COMPILER_RT_INSTALL_PATH into the external project make sure it is passed as a string not a path.
Not specifying the full path for COMPILER_RT_INSTALL_PATH isn't enough to fix the issue because relative paths specified on the CMake command line are expanded relative to the working directory before the cache is populated. Forcing this to a string allows it to remain a relative path through to the install() calls. Relative paths specified in install() calls are expanded relative to CMAKE_INSTALL_PREFIX at install time.
llvm-svn: 250834
Summary:
Many small improvements to LLVM_BUILD_EXTERNAL_COMPILER_RT.
* Works correctly with Ninja by working around CMake Bug 14771 (https://cmake.org/Bug/view.php?id=14771)
* Has install-compiler-rt target, and installs as part of the default install target
* Sets the install paths properly so that it matches the non-standalone build
* Only generate the test targets if(LLVM_INCLUDE_TESTS)

Summary: When LLVM/Clang is built without ARM support, the ios_kext runtime
library is not built, but without this patch, the Makefile still tries to
copy it. This is a recent regression, because the ios_kext library used
to also be built on x86_64.

Summary:
This corresponds to a patch to compiler-rt (D13112).
Xcode 7 doesn't support targeting iOS5 and earlier. Instead of just dropping cc_kext_ios5, I've repurposed it to cc_kext_ios, and I'm pulling the iOS architectures out of cc_kext. Putting OS X and iOS slices inside the same archive was just odd.

Summary:
UBSan is now used in the same way as ASan, and is supported on
OSX and on iOS simulator. At the moment ASan and UBSan can't be used
together due to PR21112, but I hope to resolve it soon by
embedding UBSan into ASan.
Test Plan: regression test suite.

They autotools build has a number of missing features, supports less
OS, architectures, build configurations, doesn't have any tests and
is hard to support in sync with CMake build.

This reverts the runtime library portion of r194168. As of r221621,
the libclang_rt libraries for Darwin build with explicit SDK options
so there is no need to set SDKROOT here.
llvm-svn: 221625
This was already set up for the iOS simulator ASan dylib simulator,
and this change extends that to the other iOS runtime libraries.
This is in preparation for building all those iOS libraries against
the real SDKs instead of the fake SDKs in compiler-rt.

Call it "libclang_rt.builtins-<arch>.a" to be consistent

asan_cxx containts replacements for new/delete operators, and should
only be linked in C++ mode. We plan to start building this part
with exception support to make new more standard-compliant.

from (external) compiler-rt build tree into LLVM/Clang build tree in
LLVM_BUILD_EXTERNAL_COMPILER_RT mode.
For instance, running
make asan -j12
in LLVM/Clang build tree will now build Clang, use it to configure
compiler-rt build tree, and invoke "make asan -j12" there. ASan runtime will
be built in the proper location, where Clang driver expects to find it.
Running
make check-asan
will build Clang, use it to configure compiler-rt build tree, build everything
there, and then run "make check-asan" in compiler-rt build tree using just-built
Clang and ASan runtime.
llvm-svn: 204463
With this change, one may set LLVM_BUILD_EXTERNAL_COMPILER_RT option
to build compiler-rt libraries with just-built Clang.
make compiler-rt
in the build tree will build all compiler-rt libraries with just-built Clang
and copy them to the proper location in the Clang resource directory.
make check-compiler-rt
will run the compiler-rt test suite using just-built Clang and runtime
libraries.
The goal is to make LLVM_BUILD_EXTERNAL_COMPILER_RT the default, so that
we can always build compiler-rt libraries with Clang, not the host compiler,
and for all the platforms Clang can target.

The soft-float variants of (embedded) libclang_rt only make sense for ARM, so
there's no point in trying to build them if the compiler is only capable of
targeting x86.

This builds extra versions of compiler-rt targeting various unhosted targets.
Only built on Darwin since even though they're not iOS or OSX, they share some

When using the configure build system, the libc++ headers were being
installed in lib/, whereas cmake installs them in include/. Since
include/ makes more sense for headers, we'll make both systems install
headers there.

DataFlowSanitizer is a generalised dynamic data flow analysis.
Unlike other Sanitizer tools, this tool is not designed to detect a
specific class of bugs on its own. Instead, it provides a generic
dynamic data flow analysis framework to be used by clients to help
detect application-specific issues within their own code.

to build and one had grown out of sync. Put this list in a variable so
this doesn't happen again.
The whole thing here is somewhat suspicious as we don't support 32-bit
environments with a 64-bit bi-arch capable compiler, but none have
complained yet about this so I'm just leaving it alone.

* libclang_rt-san-* is sanitizer_common, and is linked in only if no other
sanitizer runtime is present.
* libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on
a C++ ABI library, and is always linked in.
* libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a
C++ ABI library, and is only linked in when linking a C++ binary.
This change also switches us to using -whole-archive for the ubsan runtime
(which is made possible by the above split), and switches us to only linking
the sanitizer runtime into the main binary and not into DSOs (which is made
possible by using -whole-archive).
The motivation for this is to only link a single copy of sanitizer_common
into any binary. This is becoming important now because we want to share
more state between multiple sanitizers in the same process (for instance,
we want a single shared output mutex).
The Darwin ubsan runtime is unchanged; because we use a DSO there, we don't
need this complexity.
