bors c0bb3b98bb Auto merge of #143290 - azhogin:azhogin/link-pub-async-impls, r=oli-obk pub async fn impl is monomorphized when func itself is monomorphized Implentation coroutine (`func::{closure#0}`) is monomorphized, when func itself is monomorphized. Currently, when `pub async fn foo(..)` is exported from lib and used in several dependent crates, only 'header' function is monomorphized in the defining crate. 'header' function, returning coroutine object, is monomorphized, but the coroutine's poll function (which actually implements all the logic for the function) is not. In such situation, `func::{closure#0}` will be monomorphized in every dependency. This PR adds monomorphization for `func::{closure#0}` (coroutine poll function), when func itself is monomorphized. Simple test with one lib async function and ten dependent crates (executable) that use the function, shows 5-7% compilation time improvement (single-threaded).		2025-09-01 10:54:40 +00:00

README.md

The tests in this directory are shared by two different test modes, and can be run in multiple different ways:

./x.py test coverage-map (compiles to LLVM IR and checks coverage mappings)
./x.py test coverage-run (runs a test binary and checks its coverage report)
./x.py test coverage (runs both coverage-map and coverage-run)

Maintenance note

These tests can be sensitive to small changes in MIR spans or MIR control flow, especially in HIR-to-MIR lowering or MIR optimizations.

If you haven't touched the coverage code directly, and the tests still pass in coverage-run mode, then it should usually be OK to just re-bless the mappings as necessary with ./x.py test coverage-map --bless, without worrying too much about the exact changes.
