From 215b377cc327dbd1140fbc0168b69fa8ae345c6d Mon Sep 17 00:00:00 2001 From: Rémy Rakic Date: Fri, 1 Apr 2022 20:59:23 +0200 Subject: extend `EventArgRecorder` into span-aware `SpannedEventArgRecorder` The self-profiler's `EventArgRecorder` is general-purpose in its ability to record Strings (and `rustc_span` depends on the crate its defined in, `rustc_data_structure`). Some generic activities could use recording locations where they happen in the user's code: to allow e.g. to track macro expansions and diagnose performance issues there. This adds a `SpannedEventArgRecorder` that can record an argument given as a span, rather than a String, since turning spans into Strings can be tricky if you're not happy with its default Debug output. This way the recorder can have a `record_arg_spanned` method which will do that. --- compiler/rustc_span/src/lib.rs | 2 ++ 1 file changed, 2 insertions(+) (limited to 'compiler/rustc_span/src/lib.rs') diff --git a/compiler/rustc_span/src/lib.rs b/compiler/rustc_span/src/lib.rs index b0307cc20d1..f22faef2580 100644 --- a/compiler/rustc_span/src/lib.rs +++ b/compiler/rustc_span/src/lib.rs @@ -59,6 +59,8 @@ pub use symbol::{sym, Symbol}; mod analyze_source_file; pub mod fatal_error; +pub mod profiling; + use rustc_data_structures::stable_hasher::{HashStable, StableHasher}; use rustc_data_structures::sync::{Lock, Lrc}; -- cgit 1.4.1-3-g733a5
