Remove mono item collection strategy override from -Zprint-mono-items Previously `-Zprint-mono-items` would override the mono item collection strategy. When debugging one doesn't want to change the behaviour, so this was counter productive. Additionally, the produced behaviour was artificial and might never arise without using the option in the first place (`-Zprint-mono-items=eager` without `-Clink-dead-code`). Finally, the option was incorrectly marked as `UNTRACKED`. Resolve those issues, by turning `-Zprint-mono-items` into a boolean flag that prints results of mono item collection without changing the behaviour of mono item collection. For codegen-units test incorporate `-Zprint-mono-items` flag directly into compiletest tool. Test changes are mechanical. `-Zprint-mono-items=lazy` was removed without additional changes, and `-Zprint-mono-items=eager` was turned into `-Clink-dead-code`. Linking dead code disables internalization, so tests have been updated accordingly. 2025-05-09 10:36:07 +02:00			`//@ compile-flags:-Clink-dead-code`

Convert codegen-unit tests to use `start` instead of `main` The new Termination traits brings in the unwinding machinery and that blows up the required `TRANS_ITEM`s. 2017-12-22 15:31:51 +01:00

ty: remove obsolete printer This commit removes the obsolete printer and replaces all uses of it with `FmtPrinter`. Of the replaced uses, all but one use was in `debug!` logging, two cases were notable: - `MonoItem::to_string` is used in `-Z print-mono-items` and therefore affects the output of all codegen-units tests. - `DefPathBasedNames` was used in `librustc_codegen_llvm/type_of.rs` with `LLVMStructCreateNamed` and that'll now get different values, but this should result in no functional change.
