From 22f6aeecb2122630e4b27e7018c9fb47d17edda5 Mon Sep 17 00:00:00 2001 From: Dean Michael Berris Date: Tue, 28 Nov 2017 11:49:22 +0000 Subject: [XRay][compiler-rt][Darwin] Minimal XRay build support in Darwin This change is the first in a series of changes to get the XRay runtime building on macOS. This first allows us to build the minimal parts of XRay to get us started on supporting macOS development. These include: - CMake changes to allow targeting x86_64 initially. - Allowing for building the initialisation routines without `.preinit_array` support. - Use __sanitizer::SleepForMillis() to work around the lack of clock_nanosleep on macOS. - Deprecate the xray_fdr_log_grace_period_us flag, and introduce the xray_fdr_log_grace_period_ms flag instead, to use milliseconds across platforms.
