bors 227abacaef Auto merge of #120003 - Mark-Simulacrum:opt-promoted, r=davidtwco ... perf: Don't track specific live points for promoteds We don't query this information out of the promoted (it's basically a single "unit" regardless of the complexity within it) and this saves on re-initializing the SparseIntervalMatrix's backing IndexVec with mostly empty rows for all of the leading regions in the function. Typical promoteds will only contain a few regions that need up be uplifted, while the parent function can have thousands. For a simple function repeating println!("Hello world"); 50,000 times this reduces compile times from 90 to 15 seconds in debug mode. The previous implementations re-initialization led to an overall roughly n^2 runtime as each promoted initialized slots for ~n regions, now we scale closer to linearly (5000 hello worlds takes 1.1 seconds). cc https://github.com/rust-lang/rust/issues/50994, https://github.com/rust-lang/rust/issues/86244		2024-01-20 11:21:28 +00:00
