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 llvm-svn: 276251
