ty: remove obsolete printer

2020-08-30T17:59:07+00:00

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.

instance: only polymorphize upvar substs

2020-08-09T13:53:33+00:00

This commit restricts the substitution polymorphization added in #75255 to only apply to the tupled upvar substitution, rather than all substitutions, fixing a bunch of regressions when polymorphization is enabled. Signed-off-by: David Wood

instance: polymorphize `FnDef` substs

2020-08-07T17:41:45+00:00

This commit extends previous polymorphization of substs to polymorphize `FnDef`. Signed-off-by: David Wood

instance: always polymorphize substs

2020-08-07T17:41:41+00:00

By always polymorphizing substitutions, functions which take closures as arguments (e.g. `impl Fn()`) can have fewer mono items when some of the argument closures can be polymorphized. Signed-off-by: David Wood

sess: disable polymorphisation

2020-07-22T14:36:24+00:00

This commit disables polymorphisation to resolve regressions related to closures which inherit unused generic parameters and are then used in casts or reflection. Signed-off-by: David Wood

mir: `unused_generic_params` query

2020-07-20T18:35:30+00:00

This commit implements the `unused_generic_params` query, an initial version of polymorphization which detects when an item does not use generic parameters and is being needlessly monomorphized as a result. Signed-off-by: David Wood
