* [compiler-rt][XRay] re-submitting r276117, with fixes for build breakage due ↵Dean Michael Berris2016-07-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | to extraneous and missing dependencies and attempts to build on unsupported OSes Summary: This is a fixed-up version of D21612, to address failure identified post-commit. Original commit description: This patch implements the initialisation and patching routines for the XRay runtime, along with the necessary trampolines for function entry/exit handling. For now we only define the basic hooks for allowing an implementation to define a handler that gets run on function entry/exit. We expose a minimal API for controlling the behaviour of the runtime (patching, cleanup, and setting the handler to invoke when instrumenting).

* [CMake] Support platform building builtins without a full toolchainChris Bieneman2016-05-091-66/+8
| | | | | | | | | | | | | | | | | | | | | | | Summary: This patch adds support for building lib/builtins without a fully functioning toolchain. It allows you to bootstrap a cross-compiler, which previously couldn't be done with CMake. This patch contains the following specific changes: * Split builtin-specific code out of config-ix.cmake into builtin-config-ix.cmake * Split some common CMake functionality needed by both builtins and sanitizers into base-config-ix.cmake * Made lib/builtins/CMakeLists.txt able to be a top-level CMake configuration I have tested this on Darwin targeting embedded Darwin, and on FreeBSD x86_64 targeting FreeBSD AArch64. This patch depends on http://reviews.llvm.org/D19692, and is the last part of http://reviews.llvm.org/D16653.

This will also come in handy if one would want to configure several compiler-rt build trees on the same host, using just-built Clang that can target many architectures.

* Let cmake infer source file language by the file extension.Douglas Katzman2015-07-281-1/+1
| | | | | | | | | | | | | | | | | | This applies default compiler flags to .S files, in particular removing the "-pedantic" option, which is desirable because there is nothing to reasonably warn about; and the only thing that gcc warns about is that you allegedly can't correctly invoke GLUE2 in lib/builtins/assembly.h on platforms for which USER_LABEL_PREFIX is the empty string. In the gcc bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=33305 that added the warning, a commenter notes that giving a macro of zero characters to another macro is not precisely the same as failing to supply an argument, and "there is a widespread belief in C++ community that such usage is valid". Unfortunately the only way to silence the warning is to avoid -pedantic.

* [CMake] Workaround for PR24222: don't fail if we can't target ↵Alexey Samsonov2015-07-241-0/+7
| | | | | | | | | | | | | | | | | | | COMPILER_RT_TEST_TARGET_TRIPLE unless it was explicitly set. Summary: Although we assume that we can always target host triple, relax this check to avoid failing at configure-time for cases when we are not able to correctly infer/verify host triple for some reasons. See http://llvm.org/bugs/show_bug.cgi?id=24222 for more details.
