From f437e35671089ab3bdbf11b65a53fe22b9f24172 Mon Sep 17 00:00:00 2001 From: Keith Wyss Date: Tue, 17 Apr 2018 21:32:43 +0000 Subject: [XRay] Add clang builtin for xray typed events. Summary: A clang builtin for xray typed events. Differs from __xray_customevent(...) by the presence of a type tag that is vended by compiler-rt in typical usage. This allows xray handlers to expand logged events with their type description and plugins to process traced events based on type. This change depends on D45633 for the intrinsic definition.
