The previous method ran into problems because ICH would treat Spans
as (file,line,col) but the cache contained byte offsets and its
possible for the latter to change while the former stayed stable.
incr.comp.: Remove ability to produce incr. comp. hashes during metadata export.
This functionality has been superseded by on-import hashing, which can be less conservative and does not require extra infrastructure.

After renaming the structs and enums the htmldocck strings still
contained the old names. This lead to test failure.
These htmldocck tests have been updated to use the proper names of the
rust structs and traits.
Trait's implementations with private type parameters were displayed in
the implementing struct's documentation until now.
With this change any trait implementation that uses a private type
parameter is now hidden in the docs.
When using `#[doc(hidden)]` elements are hidden from docs even when the
rustdoc flag `--document-private-items` is set.
This behavior has been changed to display all hidden items when the flag
is active.
Use the CTL_KERN.KERN_PROC_ARGS.-1.KERN_PROC_PATHNAME sysctl in
preference over the /proc/curproc/exe symlink.
Additionally, perform more validation of aformentioned symlink.
Particularly on pre-8.x NetBSD this symlink will point to '/' when
accurate information is unavailable.
Rustdoc has for some time now used the "everybody loops" pass in the compiler to
avoid typechecking and otherwise avoid looking at implementation details.
In #46115 the placement of this pass was pushed back in the compiler to after
macro expansion to ensure that it works with macro-expanded code as well. This
in turn caused the regression in #46271.
The bug here was that the resolver was producing `def_id` instances for
"possibly unused extern crates" which would then later get processed during
typeck to actually issue lint warnings. The problem was that *after* resolution
these `def_id` nodes were actually removed from the AST by the "everybody loops"
pass. This later, when we tried to take a look at `def_id`, caused the compiler
to panic.
The fix applied here is a bit of a heavy hammer which is to just, in this one
case, ignore the `extern crate` lints if the `def_id` looks "bogus" in any way
(basically if it looks like the node was removed after resolution). The real
underlying bug here is probably that the "everybody loops" AST pass is being
stressed to much beyond what it was originally intended to do, but this should
at least fix the ICE for now...
Closes#46271
This commit prepares to enable ThinLTO and multiple codegen units in release
mode by default. We've still got a debuginfo bug or two to sort out before
actually turning it on by default.
Previously we were too eagerly exporting almost all symbols used in ThinLTO
which can cause a whole host of problems downstream! This commit instead fixes
this error by aligning more closely with `lib/LTO/LTO.cpp` in LLVM's codebase
which is to only change the linkage of summaries which are computed as dead.
Closes#46374
This commit updates LLVM with some tweaks to the integer <-> floating point
conversion instructions to ensure that `as` in Rust doesn't trap.
Closes#46298
This was added to cover up a lazy extra semicolon in #35849, but does
not actually make sense. This is removed as a part of the stabilization
of `never_type`.
