only check cg defaults wf once instantiated
the previous fixmes here didn't make too much sense as I didn't yet fully understand the code further below.
That code only runs if the predicates using our generic param default are fully concrete after substituting our default, which never happens if our default is generic.

Remove `missing_docs` lint on private 2.0 macros
798baebde1/compiler/rustc_lint/src/builtin.rs (L573-L584)
This code is the source of #57569. The problem is subtle, so let me point it out. This code makes the mistake of assuming that all of the macros in `krate.exported_macros` are exported.
...Yeah. For some historical reason, all `macro` macros are marked as exported, regardless of whether they actually are, which is dreadfully confusing. It would be more accurate to say that `exported_macros` currently contains only macros that have paths.
This PR renames `exported_macros` to `importable_macros`, since these macros can be imported with `use` while others cannot. It also fixes the code above to no longer lint on private `macro` macros, since the `missing_docs` lint should only appear on exported items.
Fixes#57569.
Add support for raw-dylib with stdcall, fastcall functions
Next stage of work for #58713: allow `extern "stdcall"` and `extern "fastcall"` with `#[link(kind = "raw-dylib")]`.
I've deliberately omitted support for vectorcall, as that doesn't currently work, and I wanted to get this out for review. (I haven't really investigated the vectorcall failure much yet, but at first (very cursory) glance it appears that the problem is elsewhere.)
Unescaped command-line arguments for Windows
Some Windows commands, expecially `cmd.exe /c`, have unusual quoting requirements which are incompatible with default rules assumed for `.arg()`.
This adds `.unquoted_arg()` to `Command` via Windows `CommandExt` trait.
Fixes#29494
Use #[track_caller] in const panic diagnostics.
This change stops const panic diagnostics from reporting inside #[track_caller] functions by skipping over them.
Change linked tracking issue for more_qualified_paths
This updates the linked tracking issue for the `more_qualified_paths` feature from the implementation PR #80080 to an actual tracking issue #86935.
Fix double warning about illegal floating-point literal pattern
This PR fixes#86600. The problem is that the `ConstToPat` struct contains a field `include_lint_checks`, which determines whether lints should be emitted or not, but this field is currently not obeyed at one point, leading to a warning being emitted more than once. I have fixed this behavior here.
Account for capture kind in auto traits migration

2229: Reduce the size of closures with `capture_disjoint_fields`
One key observation while going over the closure size profile of rustc
was that we are disjointly capturing one or more fields starting at an
immutable reference.
Disjoint capture over immutable reference doesn't add too much value
because the fields can either be borrowed immutably or copied.
One possible edge case of the optimization is when a fields of a struct
have a longer lifetime than the structure, therefore we can't completely
get rid of all the accesses on top of sharef refs, only the rightmost
one. Here is a possible example:
```rust
struct MyStruct<'a> {
a: &'static A,
b: B,
c: C<'a>,
}
fn foo<'a, 'b>(m: &'a MyStruct<'b>) -> impl FnMut() + 'static {
let c = || drop(&*m.a.field_of_a);
// Here we really do want to capture `*m.a` because that outlives `'static`
// If we capture `m`, then the closure no longer outlives `'static'
// it is constrained to `'a`
}
```
r? `@nikomatsakis`
- Add `:Sized` assertion in interpreter impl
- Use `Scalar::from_bool` instead of `ScalarInt: From<bool>`
- Remove unneeded comparison in intrinsic typeck
- Make this UB to call with undef, not just return undef in that case
special case for integer log10
Now that #80918 has been merged, this PR provides a faster version of `log10`.
The PR also adds some tests for values close to all powers of 10.
