does not evaluate whether CGU partitioning is *good*. That is the job of the compiler benchmark suite. + +All tests in this suite use the flag `-Zprint-mono-items=lazy`, which makes the compiler print a machine-readable summary of all MonoItems that were collected, which CGUs they were assigned to, and the linkage in each CGU. The output looks like: +``` +MONO_ITEM <item> @@ <cgu name>[<linkage>] <other cgu name>[<linkage in other cgu>] +``` +DO NOT add tests to this suite that use `-Zprint-mono-items=eager`. That flag changes the way that MonoItem collection works in rather fundamental ways that are otherwise only used by `-Clink-dead-code`, and thus the MonoItems collected and their linkage under `-Zprint-mono-items=eager` does not correlate very well with normal compilation behavior. + +The current CGU partitioning algorithm essentially groups MonoItems by which module they are defined in, then merges small CGUs. There are a lot of inline modules in this test suite because that's the only way to observe the partitioning. + +Currently, the test suite is very heavily biased towards incremental builds with -Copt-level=0. This is mostly an accident of history; the entire test suite was added as part of supporting incremental compilation in #32779. But also CGU partitioning is *mostly* valuable because the CGU is the unit of incrementality to the codegen backend (cached queries are the unit of incrementality for the rest of the compiler). diff --git a/tests/codegen-units/partitioning/auxiliary/shared_generics_aux.rs b/tests/codegen-units/partitioning/auxiliary/shared_generics_aux.rs index b6c568ed387..d3517df0376 100644 --- a/tests/codegen-units/partitioning/auxiliary/shared_generics_aux.rs +++ b/tests/codegen-units/partitioning/auxiliary/shared_generics_aux.rs @@ -1,7 +1,6 @@ // NOTE: We always compile this test with -Copt-level=0 because higher opt-levels // prevent drop-glue from participating in share-generics. -//@ compile-flags:-Zshare-generics=yes -Copt-level=0 -//@ no-prefer-dynamic +//@ compile-flags: -Zshare-generics=yes -Copt-level=0 #![crate_type = "rlib"] diff --git a/tests/codegen-units/partitioning/extern-drop-glue.rs b/tests/codegen-units/partitioning/extern-drop-glue.rs index d3bce7b4223..ca78c175dbf 100644 --- a/tests/codegen-units/partitioning/extern-drop-glue.rs +++ b/tests/codegen-units/partitioning/extern-drop-glue.rs @@ -1,15 +1,14 @@ -// We specify incremental here because we want to test the partitioning for incremental compilation -// We specify opt-level=0 because `drop_in_place` is `Internal` when optimizing //@ incremental -//@ compile-flags:-Zprint-mono-items=lazy -//@ compile-flags:-Zinline-in-all-cgus -Copt-level=0 +//@ compile-flags: -Zprint-mono-items=lazy -Copt-level=0 -#![allow(dead_code)] #![crate_type = "rlib"] //@ aux-build:cgu_extern_drop_glue.rs extern crate cgu_extern_drop_glue;
