Move coroutine_by_move_body_def_id into the big check_crate body owner loop
This avoids starting a parallel loop in sequence and instead runs all the queries for a specific DefId together.

also adjust the wording a little so that we don't say "the error occurred here" for two different spans
|
|
In some contexts, const expressions are OK. Add a `here` to the error
message to clarify this.

This silences an ICE.

workingjubilee:apple-likes-frame-pointers-but-not-that-much, r=madsmtm
compiler: set Apple frame pointers by architecture
All Apple targets stop overriding this configuration and instead use the default base of FramePointer::NonLeaf, which means some Apples will have less frame pointers in leaf functions.

Limit the size of cgu names when using the `-Zhuman-readable-cgu-name…
…s` option
Prior to this change, cgu names could be generated which would result in filenames longer than the limit imposed by the OS.

This hint allows the compiler to optimize its operation based on this
assumption, in order to compile faster. This is a hint, and does not
guarantee any particular behavior.
This option can substantially speed up compilation if applied to a large
dependency where the majority of the dependency does not get used. This flag
may slow down compilation in other cases.
Currently, this option makes the compiler defer as much code generation as
possible from functions in the crate, until later crates invoke those
functions. Functions that never get invoked will never have code generated for
them. For instance, if a crate provides thousands of functions, but only a few
of them will get called, this flag will result in the compiler only doing code
generation for the called functions. (This uses the same mechanisms as
cross-crate inlining of functions.) This does not affect `extern` functions, or
functions marked as `#[inline(never)]`.
Some performance numbers, based on a crate with many dependencies having
just *one* large dependency set to `-Z hint-mostly-unused` (using
Cargo's `profile-rustflags` option):
A release build went from 4m07s to 2m04s.
A non-release build went from 2m26s to 1m28s.

Apple targets can now overriding this configuration and instead use the

Fast path for stalled obligations on self ty
If we see that the `self` type of a goal is an infer var, then don't try to compute the goal at all, since we know that it'll be forced ambiguous.
This is currently only implemented when there are no opaques in the environment. We could extend it to check that the self type is not related to any already defined opaques via subtyping, but I'll leave that as a follow-up.
---
Also stall coerce and subtype predicates if both of their vars are not resolved to concrete types.
---
~~Also, we don't care if the goal is higher-ranked for the sized and copy/clone fast path.~~ pulling this out into another PR.

canon_abi: make to_erased_extern_abi just a detail in formatting
I think ideally we'd avoid ever printing `CanonAbi` to users, but that needs further changes. Personally I think it's fine for Miri to use the debug printing of `CanonAbi` until we figure that out, but I think others disagree. ;)
