2016-07-21[compiler-rt][XRay] re-submitting r276117, with fixes for build breakage due ↵Dean Michael Berris
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). Fixes include: - Gating XRay build to only Linux x86_64 and with the right dependencies in case it is the only library being built - Including <cstddef> to fix std::size_t issue Reviewers: kcc, rnk, echristo Subscribers: mehdi_amini, llvm-commits Differential Revision: https://reviews.llvm.org/D22611 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@276251 91177308-0d34-0410-b5e6-96231b3b80d8

2016-05-09[CMake] Support platform building builtins without a full toolchainChris Bieneman
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.

2015-09-08[CMake] Remove all uses of LLVM_NATIVE_ARCH.Alexey Samsonov
Instead, assume we're going to target triple specified by COMPILER_RT_DEFAULT_TARGET_TRIPLE and build runtimes for this triple (and hope that the host compiler can target them). This will help users that use cross-compiler on their host to build Clang that would work on a different architecture. 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. This doesn't change the behavior in the default build configuration. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@247099 91177308-0d34-0410-b5e6-96231b3b80d8

2015-07-28Let cmake infer source file language by the file extension.Douglas Katzman
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.
