Matthias Krüger 8fb194c86f Rollup merge of #89920 - hudson-ayers:location-detail-control, r=davidtwco ... Implement -Z location-detail flag This PR implements the `-Z location-detail` flag as described in https://github.com/rust-lang/rfcs/pull/2091 . `-Z location-detail=val` controls what location details are tracked when using `caller_location`. This allows users to control what location details are printed as part of panic messages, by allowing them to exclude any combination of filenames, line numbers, and column numbers. This option is intended to provide users with a way to mitigate the size impact of `#[track_caller]`. Some measurements of the savings of this approach on an embedded binary can be found here: https://github.com/rust-lang/rust/issues/70579#issuecomment-942556822 . Closes #70580 (unless people want to leave that open as a place for discussion of further improvements). This is my first real PR to rust, so any help correcting mistakes / understanding side effects / improving my tests is appreciated :) I have one question: RFC 2091 specified this as a debugging option (I think that is what -Z implies?). Does that mean this can never be stabilized without a separate MCP? If so, do I need to submit an MCP now, or is the initial RFC specifying this option sufficient for this to be merged as is, and then an MCP would be needed for eventual stabilization?		2021-10-23 05:28:23 +02:00
