est31	a0fc455d30	Replace absolute paths with relative ones ... Modern compilers allow reaching external crates like std or core via relative paths in modules outside of lib.rs and main.rs.	2020-10-13 14:16:45 +02:00
Yuki Okushi	687d7646de	Rollup merge of #77550 - lcnr:ty-dep-path-ct-cleanup, r=ecstatic-morse ... add shims for WithOptConstParam query calls r? @ecstatic-morse @eddyb	2020-10-13 04:07:50 +09:00

Dylan MacKenzie	e72e43c730	Replace (Body, DefId) with Body where possible ... A `Body` now contains its `MirSource`, which in turn contains the `DefId` of the item associated with the `Body`.	2020-10-04 16:07:03 -07:00

Simon Vandel Sillesen	290dca1781	MIR pass to remove unneeded drops on types not needing drop ... This is heavily dependent on MIR inlining running to actually see the drop statement	2020-09-22 23:09:07 +02:00

bors	88197214b8	Auto merge of #75573 - Aaron1011:feature/const-mutation-lint, r=oli-obk ... Add CONST_ITEM_MUTATION lint Fixes #74053 Fixes #55721 This PR adds a new lint `CONST_ITEM_MUTATION`. Given an item `const FOO: SomeType = ..`, this lint fires on: * Attempting to write directly to a field (`FOO.field = some_val`) or array entry (`FOO.array_field[0] = val`) * Taking a mutable reference to the `const` item (`&mut FOO`), including through an autoderef `FOO.some_mut_self_method()` The lint message explains that since each use of a constant creates a new temporary, the original `const` item will not be modified.	2020-09-10 05:54:26 +00:00
