Bug ID: 36926
Summary: Add a flag to disable emitting the custom event
instrumentation points
Product: XRay
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Clang
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
This allows us to control whether or not we want to emit the custom event
instrumentation points. We want this for the following reasons:
- The instrumentation points are not supported in all platforms yet. We can set
the default for these flags differently for different targets/front-ends.
- The instrumentation points are currently expensive in terms of impact in code
size as well as runtime overheads.
- Provide more controls of the XRay instrumentation features we're providing at
compile-time to allow users to make trade-offs on which kinds of sleds should
be emitted (as we add more instrumentation point types in the future).
